Hi downloaded via Library Manager but get error when compiling the ESP8266 avr/io.h

Example trying to compile Parola_Scrolling_ESP8266

Whats the best way to work round the issue ?

Any advice appreciated

Hi,

when I included Parola and this library into my project where I need ofcourse WiFi connectivity the compile fails. With error: redeclaration of 'CLOSING'.
Without Wifi it works ok (while most of the out effects don't work, but ok for me).

Is that something that can be fixed? Or do you have a suggestion for a workaround?

I'm trying to get MD_Parola to work with PlatformIO. http://platformio.org/lib/show/1389/MD_Parola
The library is available via the library manager. But the required MD_MAX72xx library is not available as far as I can see. And because of that the MD_Parola library is not working.

Any idea why it's not available as a package? Or even included in the Parola package.

Hope anyone can point me in the right direction on how to solve this. Thanks.

I'm using the latest version of the MD_Parola (3.1.1) and MD_MAX3.1.0 using an ESP32 (multiple boards) and Arduino Studio 1.8.10.
I'm using a 4 devices MAX7219 LED Matrix (tried different pieces).
I'm using the default SPI port for the MAX7219 (as there is no option to pass another SPI port).
The LED matrix works fine.
Now I wanted to read a text from an NFC Tag using the popular PN532 RFID Reader which is also connected to the SPI port with another CS Pin.

And now I have the following problem:
Both work seperately but not together. The PN532 Reader is detected but as soon as the text scrolling is used in the loop (using exactly the simple scoll example from MD_Parola), the reader does no longer read/find NFC Tags, if I comment out the loop part below the reader works.
if (P.displayAnimate())
{
if (newMessageAvailable)
{
strcpy(curMessage, newMessage);
newMessageAvailable = false;
}
P.displayReset();
}

I don't get an error, it does just does not find NFC tags.

I also tried the following:
I used another SPI port (VSPI) with the GPIO Pins 12,13,14,15 which is actually isolated from the default port (HSPI) on 18,19,23,5 it does not work either only if I comment out the P.DisplayAnimate(). So I just assuming that there is a SPI conflict on certain devices.
If I use another RFID Reader (RC522) it seem to work but then I have other problems.

Maybe somebody has an idea what collison might be event if different SPI ports are used.

Hi,
I want to make the instance defined by dynamic settings, so I try to use a pointer. But nothing will be shown on the screen.
I make two simple examples to demonstrate the problem.

Example 1 Normal Way - Working

#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>

#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define MAX_DEVICES 4

#define CLK_PIN   27
#define DATA_PIN  25
#define CS_PIN    32

MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);

void setup(void)
{
  SPI.begin(CLK_PIN, 0, DATA_PIN, 0);
  P.begin();
  P.displayText("Hello", PA_CENTER, 100, 500, PA_SCROLL_LEFT, PA_SCROLL_LEFT);
}

void loop(void)
{
  P.displayAnimate();
}

Example 2 Pointer Way - Display Nothing

#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>

#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define MAX_DEVICES 4

#define CLK_PIN   27
#define DATA_PIN  25
#define CS_PIN    32

MD_Parola* P;

void setup(void)
{
  P = new MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);

  SPI.begin(CLK_PIN, 0, DATA_PIN, 0);
  P->begin();
  P->displayText("Hello", PA_CENTER, 100, 500, PA_SCROLL_LEFT, PA_SCROLL_LEFT);
}

void loop(void)
{
  P->displayAnimate();
}

I'm not a good coder.
Hope someone could tell me why Pointer won't work and How to modify it to make pointer work?

hi
esp 8622, md_parola 3.0.2
i have 12 display line and 3 columns, 36 matrix display.
can i use 2 for big font (from exampe) and one normal?
i try to display some text in 2'th zone, but something wrong..

0 zone and 1 zone is fordouble height, 2 for normal.
#define MAX_DEVICES 36
#define MAX_ZONES 3
#define MAX_DEVICES (MAX_ZONES * ZONE_SIZE)
#define ZONE_SIZE 12
#define ZONE_UPPER 0
#define ZONE_LOWER 1
#define ZONE_FREE 2

P.setZone(ZONE_UPPER,0, ZONE_SIZE - 1 );
P.setZone(ZONE_LOWER,ZONE_SIZE,(ZONE_SIZE2)-1 );
P.setZone(ZONE_FREE, (ZONE_SIZE2), MAX_DEVICES);

in loop ::
P.displayClear();
P.displayZoneText(ZONE_UPPER, msgH, PA_CENTER, SCROLL_SPEED, PAUSE_TIME, scrollUpper, scrollLower);
P.displayZoneText(ZONE_LOWER, msgL[cycle], PA_CENTER, SCROLL_SPEED, PAUSE_TIME, scrollUpper, scrollLower);
P.displayZoneText(ZONE_FREE,"test", PA_CENTER, SCROLL_SPEED, PAUSE_TIME, PA_SCROLL_LEFT, PA_SCROLL_LEFT);
cycle = (cycle + 1) % ARRAY_SIZE(msgL);
P.synchZoneStart();

}

and "test" take big font..can i use normal font for this?
I do not see any example for use gig font and small at the same time.

add new fonts?
P.displayClear();
P.setFont(BigFont);
P.displayZoneText(ZONE_UPPER, msgH, PA_CENTER, SCROLL_SPEED, PAUSE_TIME, scrollUpper, scrollLower);
P.displayZoneText(ZONE_LOWER, msgL[cycle], PA_CENTER, SCROLL_SPEED, PAUSE_TIME, scrollUpper, scrollLower);
P.setFont(font);
P.displayZoneText(ZONE_FREE,"test", PA_CENTER, SCROLL_SPEED, PAUSE_TIME, PA_SCROLL_LEFT, PA_SCROLL_LEFT);
cycle = (cycle + 1) % ARRAY_SIZE(msgL);
P.synchZoneStart();

When using characters of zero length, a 1 pixel gap is inserted after the character with zero length. I do this to use the Russian font without transcoding, for this I created a font where the most significant bit is zero length (208 and 209), works well, but it turns out that there is a gap of 2 pixels between the characters. It does not have any logic. Is it possible to fix this?
Sketch and font here: https://github.com/immortalserg/MD_Parola_fonts

При использовании символов нулевой длинны после символа с нулевой длинной вставляется разрыв в 1 пиксель. Я это делаю для использования русского шрифта без перекодировки, для этого создал шрифт где старший бит нулевой длинны (208 и 209), работает хорошо но получается, что между символами разрыв в 2 пикселя. Это не имеет ни какой логики. Возможно ли это исправить?

Hello,

I am using Parola on a simple configuration: 8 devices and two Parola zones.

What I want to do is have static text in one zone without any animation. The other zone will have scrolling text.

I can't seem to figure out how to do this. With a single zone (no zone) setup I could simply to Parola.print("XXX"), but this doesn't work reliably if you have more than on zone.

Using "displayZoneText()" forces me to provide an animation and a duration.

Is there any way to simply plonk text into the middle, left or right of a zone without a duration and exist effect. Therefore having text show indefinitely?

Thank you again for such a great library.

Subject of the issue

When specifying PA_NO_EFFECT as the incoming text effect for setTextEffect(), with an effect as the outgoing effect, the outgoing effect animation is ignored.

Your Environment

Library Version: all versions
Hardware model/type: all versions

Issue description

Using the code
P.setTextEffect(zone, PA_NO_EFFECT, PA_SCROLL_UP);
does not scroll up text that is already being displayed.

Workaround is to specify
P.setTextEffect(zone, PA_PRINT, PA_SCROLL_UP);
which visually looks the same but behaves as expected with the text scrolling off the display.

hello,
i made a display with 16x2 (2rows and 16columns).Total 32 8x8 matrices.
i wrote a code for double height display demo...Total 32 devices taken as two zones(bottom zone and Top Zone),,,in that P.synchZoneStart(); is not working properly...When data is scrolling the two zones are not in synchonization....the bottom zone is slight faster than top zone....

please give me suggestions,
thanq,
Sankar.

Hi,
I am trying to get my text scrolling by using displayZoneText() and/or displayText(), but whenever I try to set an effect different from static printing I won't see any text at all. Indeed, I have tried some other effects in addition to scrolling, but they won't show either.
Here a piece of code for the displayZoneText() try. The commented static text will show just nicely.
I tried displayText() without setting any zone as well...but did not work..

I would really appreciate some tips!
Thanks in advance

  //P.displayZoneText(1, "Press Start!", PA_CENTER, 0, 0, PA_PRINT, PA_NO_EFFECT);
  P.displayAnimate();
}

It would be great to add this library to the Arduino IDE library manager.
That would allow users to quickly and easily install it directly from the Arduino IDE GUI in just seconds.
It keeps the less technical users from doing things like installing it incorrectly and allows them to easily updated it when updates come out.

It isn't difficult to do, (you have to get the Arduino team to add it - but that is a one time thing)
Then after that, when you have a new release all you have to do is create a tag and the library manager will discover the new release in about an hour.
https://github.com/arduino/Arduino/wiki/Library-Manager-FAQ

BTW, it would also be helpful to add some installation instructions to the readme.

What should be changed or added in the "Parola_Zone_TimeMsg.ino" sketch to use with esp8266 (only as a board - not WiFi)? Thank you

Respected Sir/Madam,
I've uploaded this code to Arduino Mega, no problem in uploading the code and also changed the pin number, bluetooth module number correctly. While it starts up, the Dot Matrix MAX7219 displays only 'Setup' I cannot find a way to setup the bluetooth. I've read the code and it said to write 'AT+' and something like 'NAME\0\0' or '\r\n' I cannot understand how to setup this bluetooth. Please help me do this setup thing. And I am using HC-06 module.
Thank you.

Subject of the issue

~Building an internet "always right" clock project.
~Experienced weird board issues with resets, not uploading etc.
~Troubleshoot for a couple of days and have found that board resets continually if I attempt to begin an instance of MD_Parola using P.begin() after MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
~If I comment out just that line, the sketch works as expected

Your Environment

Steps to Reproduce

Uncomment line 36 in the code below being //P.begin();

Expected Behaviour

The sketch should run. The sketch runs with line 36 commented out.

Actual Behaviour

Continual resetting of board every ~8 seconds

It appears that this library is dependant on 'MD_UISwitch'
It can be fixed by installing MD_UISwitch using the library manager.

Hi,

If you load the Parola_Print_Test example from the Arduino IDE the following line seems to be missing:

const uint16_t WAIT_TIME = 1000;

If you paste it in under the defines it then compiles without errors

Thanks
Stuart

Dear congratulations for your library, as the title says I need to show temperature and humidity in double zone but I can't find something that can help me, you could be so kind as to guide me please.

This is the code I use to test my sensor and it works correctly

#include <MD_MAX72xx.h>
#include <SPI.h>

#define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW

#define DATA_PIN  11
#define CS_PIN    10

// Hardware SPI connection
MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);

#include <DHT.h>
#include <DHT_U.h>
#define DHTPIN 2     // Digital pin connected to the DHT sensor
#define DHTTYPE DHT22   // DHT 22  (AM2302), AM2321

DHT dht(DHTPIN, DHTTYPE);

void setup() {
  pinMode(3, OUTPUT);    // sets the digital pin 13 as output
  digitalWrite(3, HIGH); // sets the digital pin 13 on
  P.begin();
  dht.begin();
}

void loop() {

  delay(2000);

  float h = dht.readTemperature();

   P.setTextAlignment(PA_CENTER);
   P.print(h,0);


}

and this is the code that I tried and that I would like to use to show the sensor temperature

Subject of the issue

Describe your issue here.

Your Environment

Library Version: MD_Parola-3.1.1
Arduino IDE version: 1.8.9
Hardware model/type: ICSTATION_HW
OS and Version:Windows10

.

I have used example code of MD_Parola Library : Parola_Double_Height_v2

Expected Behaviour

In double Height font examples:
Message is Scrolling from Right to left, when scrolling is about to reach an end , the upper portion of double font stuck in 8 LED's modules while lower portion keep moving and finished flawlessly.

Thanks

Hi MajicDesigns, thanks for the consideration. The error message I got was something like "Can't find MD_Parola_H library", but as I said I'm completely new to this stuff and there's something I might be doing completely wrong. Didn't even knew there was a Daft Punk example in your libraries! Any chance you can give a step by step note on how to correctly compile that program on my Arduino?

Thanks again!

Hello,
I am using MAX7219 dot led matrix panel (16x64 combination).

everything working fine, but it has some buzzing noise.
is there any solution?

Subject of the issue

In the Double Height Fonts Only:- All the the ( effectIn ) animations which grows horizontally including Sprites; progresses at very slow speed (almost half ) of the speed of EffectOut animations. This phenomenon is directly proportional to length of textBuffer. I am using atmega1284 controller. More than 75% SRAM is free. Just tried Example code Parola_Double_Height_V2 and changed the PA_SCROLL_LEFT effect with PA_WIPE_CURSOR.
The text array which is having 3 characters wiped out at fast speed, as the length of text increases , huge difference in effectin speed and effectout speed has been observed.

This issue has become more prominent on arduino Uno. (at that time I was thinking the issue was because of free SRAM availability) thats why I shifted to atmega1284. I have observed Some what improvement in speed of effectin speed but still it takes 4 seconds to wipe cross the length of 20(20 are in upper + 20 are in lower zone) modules if I SetSpeed to 0.

I am not an expert neither of hardware nor of software.

I am just trying this Library to make Little more wide screen. Before approaching to this length of screen I have tested all the Library on 5 modules. Everything was working seamlessly.

Hope you would bear my silly mistake if I had made. Please correct me.

Looking forward valuable help from respectable MD_Parola community .
Thanks

cBuf [15] seems a bit risky. Would not it be better to ask the font which is its maximum width ???

In my case I use 22 pixels wide fonts ... and strange things happened before identifying this array of uint8_t .....

uint8_t MD_MAX72XX::getMaxFontWidth(void)
{
	uint8_t max = 0, charWidth;
	uint16_t	offset = 1;

		PRINT("\nASCII '", i);
		PRINT("' offset ", offset);
		PRINT("' max width ", max);

		if (charWidth > max)
			charWidth = max;
		offset += charWidth;
		offset++;
	}
	return max;
}

Is it possible/easy to use an alternative board to the MAX72xx or is it too tied-in? I'd like to link this library up to my OctoWS2811 based system.

Hello! Firstly, fantastic work with your library. How can I donate?

I have a small problem. I tried your Parola_Zone_Dynamic demo, which I got to work without issue. However, I wanted to set the intensity of the LED matrix to 0 (minimum), and I have discovered that it will only set the intensity of the FIRST module to 0. Not the entire display as expected.

My code is as follows (essentially a small adjustment to the Parola_Zone_Dynamic example to work with ESP8266)

// Program to demonstrate using dynamic (changing) zones with the MD_Parola library

// is displayed in the zone.

I'm trying to combine MD_Parola with aREST but it's throwing a compiler error at me. This error is only generated when I enable a custom font. It has to do with the PROGMEM identifier but my arduino knowledge it too limited to understand/fix the issue here. It could very well be that the issue is not caused MD_Parola but by the aREST lib in that case I apologise for posting it here.

This is the full error I'm getting.

Greetings Marco!
I'm using your 'Parola_Zone_TimeMsg' sketch;
I loaded a sketch 'DS3231_Serial_Easy' on the DS3231 RTC to set the time, and when I record the sketch, shows the correct time and date on the display, but Day of the Week is wrong, for example, today (I recorded the sketch) "Sunday, April 21, 2019" is showing "Saturday, April 21, 2019". Would you have any tips for me?
NOTE: On Serial Monitor shows correct: Sunday, April 21, 2019
Thank you very much

Hi,
I need to shutdown the display when i put the ESP8266 in deepsleep.
But there is no way to retrieve the _D object.
Would it be the good way to add in MD_Parola.h:
MD_MAX72XX* getMAX() { return &_D;}

and to put in my code:
P.getMAX()->control(MD_MAX72XX::SHUTDOWN, true)

Regards

i got this error message whilst upgrading the library filename has a + in it 'Parola_Test_T+G'

Enclosed screenshot of error

Hi Marco,

Testing your great library I found out that wipe (PA_WIPE) effect does not work for one segment display nor for one segment zone area.
Environment: ESP32 + MAX7219 + USE_ICSTATION_HW

How to reproduce:
Change the example Parola_Animation_Catalog example like this
#define MAX_DEVICES 1
in the sCatalog table shorten the psz from "WIPE" to "W" e.g. { PA_WIPE, "W", 5, 1 },

The program hangs and does not leave the animation, stays there for ever.
I haven't yet troubleshoot this, juts wanted to let you know :)

...anyway great job!
P.

Hi,

I took a lot of time to understand why the various effects of the demonstration do not work and in the end I found out something was wrong here:

memcpy_P(&ci, catalog + (idxCat * sizeof(catalogItem_t)), sizeof(catalogItem_t));

I'm using 3 zones of 8 modules so

typedef struct catalogItem_t
{
bool fPause;
uint8_t zFX[MAX_ZONES];
};

is 1 byte for bool and 3 bytes for zone FX.

and in fact sizeof(catalogItem_t) return 4.

At first loop idxCat is 0 so catalog + ( 0 * 4) so

memcpy_P(&ci, catalog ), 4);

catalog , if I remember correctly, is 0x110A.
At second loop I would expect:

memcpy_P(&ci,catalog + (1 * 4),4) --->>> memcpy_P(&ci,0x110A + (1 * 4),4) that becomes memcpy_P(&ci,0x110E,4) instead it becomes memcpy_P(&ci,0x111A,4) and each loop the flashram pointer increase of 0x10 instead of 0x04.

Obviously for first loops maybe you are lucky to read an effect that should be done 4 times later but in the later ones you read some of the code in flash (maybe the characters).

I have solved in that way:

    Serial.println("");
    Serial.print("memcpy_P() flash address = ");
    Serial.println( (unsigned long)catalog + idxCat * sizeof(catalogItem_t),HEX);
    Serial.print("memcpy_P() flash address = ");
    Serial.println( (unsigned long)(catalog + (idxCat * sizeof(catalogItem_t))),HEX);

    // copy the next catalog item into RAM
    memcpy_P(&ci, (const void *)((unsigned long)catalog + (idxCat * sizeof(catalogItem_t))),   sizeof(catalogItem_t));

Ciao Marco,

I have assembled a display of 3 zones of 8 displays and adapted the demos Parola_Double_Height_Test.ino and Parola_Bluetooth_Control.ino.
Apart from the previous problems that you have already fixed, another one I had noticed but attributed to a power supply problem.
Now I've found that if I turn off the DEBUG option, the display stops at startup by displaying meaningless characters but always equal to each turn on.
Thinking he had missed something I commented on all PRINTX, PRINT, #define PRINT.. , etc. The program compiles correctly and always behaves the same way, meaningless caracters.
I added in setup() Serial.begin(57600);
No change in behavior.
I added an additional Serial.println("");
Miracle, the display works properly.

At this point I do not understand why this happens, I suspected the interrupts not enabled, I added interrupts(); in setup() instead of Serial.begin and Serial.print but it does not work anyway.
It seems that Serial.print initiates something that libraries do not do ....

Hi,

I'm working on a Daft Punk Thomas helmet and I'm trying to run your code on a 8x40 LEds matrix using an Arduino Uno and 5 MAX7221 chips. I'd like to execute your code to display text on my matrix but I'm a complete newbie and it won't stop failing to compile with Arduino Software (1.8.3).
Could you help me or specify this in your documentation.

Thanks for your time.

Hardware enhancement.
Not verified.
1st time effort.
I hope it is correct.

How i can detect the end of a string scrolling ? I.E. to detect when i can change the display string ?

after trying also this library to understand usage i try first with demo codes:
the example Parola_UTF-8_Display is working if i compile "AS IS"
BUT if i set DEBUG on line 33 to 1 to see in serial whats happening
the display see only Ascii standard in the first part of the code:
"abcABC"
" "
"50€/kg"
"Espaol"
"30m/s"
"Franais"
"20s/C"
after that
"128 €"
"129 "
"130 ,"
and so on...
if i reput DEBUG back to 0 the code did not work either! the only way to test the demo is to compile the code without touching it. t is possible?

Hello.
Is it possible to adjust text using big fonts different way as left, center, right?
E.g. some pixels of left or right?

Nice, really nice project!
I wonder, how i can use a start animation (e.g. slide to left) but then should the text should stop.

I would like to have an incoming text with a nice animation. But afterwards the Text should be stay focused. And this text did have also updates.
Any chance?

Regards,
Fi

The MQTT connection drops while using PubSub and animation using P.displayText. PubSub and MD_Parola don't play well with each other? Using a ESP8266.

Hi, I tried this library, the characters show fine, but they are inverted, that means the character starts at the first display on the right side an then the character ends in the second display on the right side. (the first display being the left one.)

this is a picture: http://tinypic.com/view.php?pic=vinn88&s=9 or http://i68.tinypic.com/vinn88.jpg

I just used the hello world example, and changed the text to "AB".
thanks

Good morning,
I got errors while compiling the sprite-demo for an ESP8266:

const uint8_t F_ROCKET = 2;
const uint8_t W_ROCKET = 11;
static const uint8_t rocket[F_ROCKET * W_ROCKET] PROGMEM = {
  0x18, 0x24, 0x42, 0x81, 0x99, 0x18, 0x99, 0x18, 0xa5, 0x5a, 0x81,
  0x18, 0x24, 0x42, 0x81, 0x18, 0x99, 0x18, 0x99, 0x24, 0x42, 0x99,
};

...

parola.setSpriteData(rocket, W_ROCKET, F_ROCKET, rocket, W_ROCKET, F_ROCKET);

error: invalid conversion from 'const uint8_t* {aka const unsigned char*}' to 'uint8_t* {aka unsigned char*}' [-fpermissive]
 parola.setSpriteData(rocket, W_ROCKET, F_ROCKET, rocket, W_ROCKET, F_ROCKET);

Does anybody has a solution for that? Everything else is running perfect.

Arduino IDE version: 1.8.8
Hardware model/type: esp8266 nodemcu clone v3
OS and Version: Ubuntu 18.04.2 LTS

Steps to Reproduce

Explain how to reproduce this issue. Please provide working code below to demonstrate the issue.

https://github.com/MajicDesigns/MD_Parola/blob/master/examples/Parola_Double_Height_v2/Parola_Double_Height_v2.ino

Line 50 is unchanged, but I have ...

#define MAX_ZONES 2
#define ZONE_SIZE 3

Is 3 a large enough zone size, or do I need one more board (8x8 pixel, x4 max7219) ?

Seems fast enough software spi is not the issue (however, here's the wiring too)

#define CLK_PIN D3 // or SCK
#define DATA_PIN D2 // or MOSI
#define CS_PIN D1 // or SS

// HARDWARE SPI
// MD_Parola P = MD_Parola(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
// SOFTWARE SPI
MD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);

Expected Behavior

Explain what should happen.

Actual Behavior

Explain what happens instead. Provide log messages if relevant.

Hi,
the following statement within arduino code
uint8_t scrollIntensity = P.getIntensity();
ends up in the error message see title.

Strange, usage of
uint16_t scrollSpeed = P.getSpeed();
causes no problems, the usage of P.getCharSpacing() is working, too.

Checked up MD.Parola.h and found in class definition...
`
/**

• Get the zone brightness.
• Get the intensity (brightness) of the display.
• \return The intensity setting.
  */
  inline uint8_t getIntensity() { return _intensity; }`

right below method getCharSpacing....

Used #include and #define

#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>
.....

#define HARDWARE_TYPE MD_MAX72XX::FC16_HW
#define MAX_DEVICES 4 // Number of 8x8 modules linked together
#define CLK_PIN 13 // or SCK
#define DATA_PIN 14 // or MOSI
#define CS_PIN 12 // or SS

// SOFTWARE SPI
MD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);

I need to reduce the size of either MD_Parola or the MAX_72XX libarary by 1372 bytes. Is there a previous version that is smaller? Is there another way to make it just a little bit smaller ?

thanks.

Crash on ESP8266 (wemos d1 mini) using parola_zone_mesg example

I have a crash on the example for effects
// PA_RANDOM,
// PA_SLICE,

all I changed is

#define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HW
#define CLK_PIN D8 // or SCK
#define DATA_PIN D7 // or MOSI
#define CS_PIN D5 // or SS

MD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);

I am using 8 devices.
