m5stickc's Issues

I2c pins override

Hello, quick question, I have a library, specifically the CCS811 from adafruit, it is using the default pins, I would like to override the pins or know what i2c pins are really defined for the stick-c

Flappy Bird Example EEPROM not working

The FlappyBird has an example of EEPROM (which I need for my project) this EEPROM value is lost. ie the High Score resets to 0

Is it possible to read the IR transmitter (or LED) to detect ambient light?

I've seen various hacks on Hackaday.com to use LED's as sensors.

Does anyone think this could be leveraged within the M5StickC?

How to put LCD to sleep

I want to save power during DeepSleep, so I want to make the LCD sleep. I found “Sleep-In Mode” on page 30 of https://github.com/m5stack/M5-Schematic/blob/master/Core/ST7735S_v1.1.pdf. Can I migrate from software to this?
Or is there a way to save power as well?
I tried M5.Axp.ScreenBreath (7), but it seems that the battery runs out within one day even with DeepSleep.

RTC constructor should not call Wire1.begin()

In

M5StickC/src/RTC.cpp

Lines 5 to 7 in 3f8f30d

	RTC::RTC(){
	Wire1.begin(21,22);
	}

, Wire1.begin() is called in a constructor. This is bad form, and none of the other modules do it. Wire1 setup should be moved into an rtc.begin() function.

While it seems to work fine in Arduino, I'm using PlatformIO to build the ENV example. When Wire1.begin() is present in the RTC initializer, the program crashes before setup() with an "uninitialized data" diagnostic on serial. Because it crashes before setup(), this implies something bad is going on before then — probably in constructors.

In_espi min() conflict with sstream

compile simple code like this:

#include <M5StickC.h>
#include <iostream>
#include <sstream>

void setup() {
  // put your setup code here, to run once:
}
void loop() {
  // put your main code here, to run repeatedly:
}

and get error:

Default AXP192 charging current

According the datasheet of AXP192, it's currently configured to charge the battery at 190mA (in AXP192.cpp), which is a bit too much for an 80mAh cell. Would you consider lowering the default to 100mA instead? It'll probably make the bettery last more cycles in the future.

UNIT_LIGHT - Wrong INPUT PIN

Should be pinMode(32, INPUT);

RTC interrupt pin connected to ESP32 or not?

Hi there,

I would like to know that have you connected the BM8563 RTC chip's INT pin to ESP32 or not? It may be helpful for waking up or notifying the microcontroller.

Please add M5StickC display support to esphome

Hello. I am using a couple of M5StickC devices as esphome nodes, with sensors attached, deep_sleep, buttons, IR transmitter, etc.. Here’s one of my configs
https://github.com/apolselli/home-assistant-config/blob/master/esphome/m5stickc.yaml

It’s a pity that I still can’t use the internal display to show some sensors’ or system info.

Please add support for that display in esphome (a wonderful lib to integrate esp32 devices in home assistant). It should be very easy since the arduino code is already there... And of course, other components are welcome too.

Thank You

M5StickC CardKB First Time usage

Hi

I run the CardBK example with the CardBK connected but get no repsonse on screen or when press keys.

Do I need to flash the CardBK first with the keyboard firmware or should it be already loaded?

For Cardkb hat \ does not exist

Instead of \ my Cardkb hats output / if the second from the right button on the 4th row labelled \ / = is pressed.
If your atmega firmware is the culprit, I need a fixed firmware and instructions how to flash it, because \ and / are definitely different symbols...

Rotate text in screen

Hello I was wondering hot to rotate the text, I tried this code but didn't work:

// text print
  M5.Lcd.fillScreen(BLACK);
  M5.Lcd.setTextDatum(MR_DATUM);
  M5.Lcd.setCursor(0, 10);
  M5.Lcd.setTextColor(WHITE);
  M5.Lcd.setTextSize(4);
  M5.Lcd.printf("hello world");

IR Pin Clarification

On the Label on the Back of the M5StickC the IR PIN is shown as GPIO10 ... but in the examples and in the matrix on this Page it is shown as GPIO9..

Which is it?

How is the "M5Display::drawBitmap" supposed to work

Hey,

I can not get the "M5Display::drawBitmap" to work properly...

I can not even display a simple color gradient. I just get some wierd 5x6,5 small gradient boxes on the screen.

What is the correct format for the data array?

WiFi and BLE range very short

I'm using the M5Stick but I find that the WiFi and BLE range is really short. Does anyone else is experiencing the same ?

Using M5.6886 api, yaw will always drift

Hi there,
I have been trying to debug getAhrsData(&pitch,&roll,&yaw) without success.
With the M5StickC on the table without movement the values I get for yaw keeps growing in circles.

I did take a look into MahonyARSupdateIMU and other versions available on the internet but still cant get it to work properly.

Gist of the values:

<script src="https://gist.github.com/jokandre/be502bc3ed397fcd13013df5cd740ddd.js"></script>

Advice on how can I fix it is much needed.
I know that it needs to calibrate. But there is no documentation about it. Also there is nothing on the code inside the library to do it.
If I should not use the M5StickC library at least tell me what should I use instead. Thanks

TFT_Terminal.ino for 160x80

Please correct TFT_Terminal.ino sketch for proper operation with 160x80 display.
Currently in several places still is set 320 as a width value.
Also vertical scroll does not work correctly.

Factory Test incorrectly displays number of APs

These lines contain a printf without any parameter.

M5StickC/examples/Basics/FactoryTest/FactoryTest.ino

Line 54 in 7811286

M5.Lcd.printf("%d AP");

M5StickC/examples/Basics/FactoryTest/FactoryTest.ino

Line 58 in 7811286

M5.Lcd.printf("%d AP");

This should be changed to:
M5.Lcd.printf("%d AP", n);

Better yet, the commons lines inside the if statement should be brought out:

    if (n == 0) {
      M5.Lcd.setTextColor(RED, WHITE);
    } else {   
      M5.Lcd.setTextColor(GREEN, WHITE);
    }

    M5.Lcd.printf("%d AP", n);

M5 StickC WAV playback not working

Hi there,
I am trying to use the M5 StickC SPK / SPEAKER HAT to play back some WAV. Could you please confirm if this is possible? The SPK example https://github.com/m5stack/M5StickC/blob/master/examples/Hat/SPEAKER/SPEAKER.ino seems to imply it's possible, but I don't see it working in the example and I haven't seen an example that I was able to make work.

Thanks for your support!
Jan

Could you tag the code and update the version on the Arduino files?

The latest update was almost two months ago and since then there have been some important fixes (like the IMU changes). Could you add a new tag to the repo and update the version, so the changes are available also on the Arduino IDE?.

Please add components

M5.Lcd.sleep() compile error

Can SH200Q detect tilt to gravity?

I would like to calculate posture of M5StickC.
But it seems that accelerometer in SH200Q does not reflect gravity acceleration.

Yaw value keeps increasing/decresing even without movement

Hi there,
I have been trying to debug getAhrsData(&pitch,&roll,&yaw) without success.
With the M5StickC on the table without movement the values I get for yaw keeps growing in circles.

I did take a look into MahonyAHRSupdateIMU and other versions available on the internet but still cant get it to work properly.

This happens only for yaw. Pitch and roll values are quite stable after few seconds.

Usage of Wire library.

In the files:

• M5StickC/examples/Hat/ENV/DHT12.cpp
• M5StickC/examples/Basics/FactoryTest/DHT12.cpp

These lines are not needed:

delay(50);
if (Wire.available()!=0) return 2;

Does the sensor need that delay before using other functions ? That delay is not needed for the I2C bus. The line "if (Wire.available()!=0) return 2;" is always zero, there is not need to check that.

See also my alternative explanation of the functions of the Wire library.

In the file

• M5StickC/examples/Hat/ENV/bmm150.cpp

all the Wire.beginTransmission() before and Wire.endTransmission() after a Wire.requestFrom() may be removed.
Explanation: Common-mistakes, number 2 and 3.

Unable to receive interrupts from AXP192

I've been trying to receive interrupts from the AXP192 via GPIO35 to (hopefully) detect the power button press as an interrupt. Button A and B have no issues with this as they are directly hooked up to GPIO37 and GPIO39 respectively,
Here are some code snippets:

// Method in AXP192.cpp to enable all IRQ flags by writing to registers 0x40, 0x41, 0x42, 0x43
void AXP192::enableAllIRQ() {
    uint8_t val = 0xFF;
    for (int i = 0; i < 4; i++) {
        Write1Byte(0x40 + i, val);
    }
}

// method to be called when interrupt is triggered
void IRAM_ATTR isr() {
    axpIrq = 1;
}

// The following methods are called during setup
void setup() 
{
// other functions...
// setup GPIO35 as input
pinMode(35, INPUT_PULLUP);
// attach interrupt service routine
attachInterrupt(35, isr, FALLING);
// some method to clear IRQs
}

void loop()
{
    // trigger if axpIrq flag is set
    if (axpIrq) {
        Serial.printf("INTERRUPT DETECTED\n");
        // reset flag
        axpIrq = 0;
    }
}

That's the rough gist of the code I'm working with now. Is there anything else I'm missing?

Deep Sleep and Display

Hi,
it seems that the deep sleep mode does not shut down the display. When using following code the display stays on:

Is there anything we can do about?

AXP192 battery current

A few days ago I ported the Arduino AXP192 code to micropython (see https://github.com/karfas/M5StickC-uPy).
It works, but some questions arised:

1. Has someone a pointer to an English datasheet of the AXP192 ?

2. In AXP192::GetBatCurrent(), the current to the battery is calculated from 13 bits read from the AXP address 0x7a.
   In AXP192::GetBatChargeCurrent(), the battery current is read from 12 bits at address 0x7a.
   Code is pasted below.

Which version is correct ? The ReadXXBit() functions are also not helpful - these shift the first byte read 3/4 bits and ADD the second byte without any mask).

Kind regards,

Thomas

float AXP192::GetBatCurrent()
{
    float ADCLSB = 0.5;
    uint16_t CurrentIn = Read13Bit( 0x7A );
    uint16_t CurrentOut = Read13Bit( 0x7C );
    return ( CurrentIn - CurrentOut ) * ADCLSB;
}

float AXP192::GetBatChargeCurrent()
{
    float ADCLSB = 0.5;
    uint16_t ReData = Read12Bit( 0x7A );
    return ReData * ADCLSB;
}

Dices problem

Dices wouldn't work beyond the Shake Me message so I changed the IMU to MPU6886 and 1 was showing two spots so I adjusted the condition in the for loop in draw_dice() to d < 6. The code now works on my M5StickC and is as follows:

LCD: readPixel(), readRect(), readRectRGB() doesn't work

ReadPixel(), readRect() and readRectRGB() doesn't return real pixel values from LCD.

For example (for black and white pixels on the screen):

for (unsigned y = 0; y < TFT_HEIGHT; ++y) {
 for (unsigned x = 0; x < TFT_WIDTH; ++x) {
   Serial.printf("%s", M5.Lcd.readPixel(x, y) ? "#" : " ");
 }
 Serial.printf("\n");
}

This routine prints blank output though in reality display has a lot of white pixels printed on black background.

I would like to implement auto LCD orientation update so I need to get full dump of display pixels. BTW I suggest you to consider this functionality within M5.update() routine.

There are some problems when flashing Arduino projects (a fatal error occurred: failed to connect to ESP32: invalid packet header (0x4F)) Download speed and board are correct. When I flash in Ui Flow the exact same problem. Drivers set from quick guide. How fix this?

Add a Microphone demo

I would like to use this wristwatch wearable to record my voice and send it to a home server, in order to do some voice recognition and home automation.

But I can not find any example code about the SPM1423.

Any clue would be welcome.

How to use Grove VL53L0X?

Hi.
I am trying to run the Mstack VL53L0X grove module in M5stickc and it is impossible.
Is there any special configuration to make it work?

Thank you

Request for Voice Recognition

Hello all,

I would like to use M5stick to detect voice commands at any time, even without internet. I know there are some frameworks that exist, however, most of them are not meant for Arduino IDE. There seems to be no Arduino library for ESP32 for voice recognition.

I am aware that this example exists for M5StickC:

https://github.com/m5stack/M5StickC/blob/master/examples/Basics/Micophone/Micophone.ino

Some repositories for ESP32 voice recognition I found are:

https://github.com/espressif/esp-skainet
https://github.com/MhageGH/esp32_CloudSpeech

With that said, it means that it is very possible to do voice recognition with only ESP32 and a compatible microphone. Can someone point out how or when there would be an example for Arduino IDE?

Where is the original software?

Where might I find the source of the code that ships with the M5StickC? It has these modes:

• 3D box rendered according to the accelerometer report.
• reads the RTC and writes it to the screen in a big font.
• scrolling FFT display of the microphone input
• Sending IR data
• BLE connecting.

M5Stick C did not display anything after flash

I tried flashing my M5StickC with Arduino (just tested hello-world program) The uploading was fine, but the board did not displayed anything and I did not have any evidence for the cause.
I also attached the log here.

Incorrect vertical height in TFT_Terminal.ino

When running the example, lines don't show until several Carriage Returns have been inputted. I believe this to be due to the vertical height for display being incorrect. YMAX is currently set to 160. It should be 80.

turn off display

the function M5.Lcd.setBrightness(0) returns the following when compiling:

C:\Users\user\Documents\Arduino\M5stickC_rtc/M5stickC_rtc.ino:55: undefined reference to `M5Display::setBrightness(unsigned char)'

collect2.exe: error: ld returned 1 exit status

I'm using M5.Axp.SetSleep() as a workaround for now, but it seems inconsistent when the rest of the functions listed here work fine.

Smooth fonts

Could you add Smooth font support for the internalization of the project?
Need to change In_eSPI.h and .cpp and set definition:
#define SMOOTH_FONT

LCD controller: ST7735R or ST7735S??

Hi there,

Maybe I was wrong but it seems that the screen is ST7735R, same as this one: https://www.adafruit.com/product/3533

...and the datasheet is: https://cdn-shop.adafruit.com/datasheets/ST7735R_V0.2.pdf

Also I suggest you should remove the initialize sequence for other LCD panels: https://github.com/m5stack/M5StickC/blob/master/src/utility/ST7735_Init.h#L12

The VCOM voltages and Gamma LUT are different. If someone wants to port it to other platforms (non-OS or pure ESP-IDF, no Arduino), they may be confused and use the wrong settings. The wrong settings could result in weird color or even killing the panel.

Jackson
