Issue of using the library on a Arduino UNO Wifi Rev 2... about md_parola

[MajicDesigns]

Snippets don't work too well because I cannot see what else your program is doing, which is often where the issues are.

As I understand your requirements: you have 4 matrices; each matrix is a zone; each matrix will display a single numeric digit; the only animation used is PA_PRINT.

From what you have given, I think the structure of your loop() may be causing a problem because you are continuously sending the data (hundreds of times a second) and erasing the data immediately with the displayReset(). This may be just in the snippet, but that is what I can see.

PA_PRINT will take one animation cycle to display, so I imagine this is a lot faster than your baseball score will change. I would make sure the loop only updates the display when the data changes, more like

matrix.displayAnimate()
if (any of the data has changed)
{
  sprintf(szInnings, ";%d", innings);
  sprintf(szHome, "%d", homeScore);
  sprintf(szAway, "%d", awayScore);
  sprintf(szBrightness, "%d", brightness);
  matrix.displayReset(0);
  matrix.displayReset(1);
  matrix.displayReset(2);
  matrix.displayReset(3);
}

You keep track of when the data changes either by setting an 'old' value for each and then comparing to the current or more easily (with such a small amount of data) by just setting a global boolean flag when you change any of the displayed values. This is then used to trigger the update and reset to false in the 'if' statement.

An alternative is to get rid of the zones altogether. You are using a fixed font, so the spacing will be constant and you can work out where things will land on the display easily. Then use

sprintf("%d %d %d %d", innings, homeScore, awayScore, brightness);

to format one string for the display. Using one zone you can just use the .print() method or the native displayAnimate() method (however, the same comments as above apply for updates in loop()).

Thanks for your reply.

I'm not to used to writing codce for the Arduino and I see your point about updating the matrixes to often. There is a bit of code where I today are updating the values to show in the matrixes so I will move the displayReset command to inside the if statements for the update. I will report the progress.

I would just lift one question, the code is working correctly on a normal Arduino UNO but it's only on a Uno Wifi I'm getting this issue. I can reconnect to a UNO and use the same hardware for the matrixes and buttons and I get it to work with the same test program. I understand that I got a collision on the UNO Wifi since the network also using the SPI interface so that I have fixed. But the last of the displays will not work on the UNO Wifi.

Are there some differences in the architecute between the two more than that it's a built in WiFi shield on the UNO Wifi?

Main code of the program

`/*****************************************************************

• Program to han dle the score controling os a basevall game. The score and information will
• be sent to the ScoreBoard over IP.
• It's only possible to have one ScoreControl but it should be possible to have multiple ScoreBoards
• Format of input information are:
• Message format
• 1111111111222
• 1234567890123456789012
• #I=XXH=XXA=XXO=XB=XXX&
• I=XX - Inning with first X to include : for TOP and ; for BOTTOM, Second X tgo include the inning number
• H=XX - Home score with zero filled, one of two digits
• A=XX - Away score with zero filled, one of two digits
• O=X - Outs, will be 0, 1, 2 or 3
• B=XX - Brightness with zero filled, one of thress digits (0-255)
• & - end line sign
• Program controlls the following buttons and matrixes:

• BUTTONS

• Inning count up and down. (Low value is TOP 1 and high value is 0 BOTTOM which is the extra inning)

• Home score up and down

• Away score up and down

• Outs (Cycles from 0 to 3 and then resets to 0)

• Brightness (To control the brightness of the lep strips in the ScoreBoard)

• Reset (NEEDS TO BE DOUBLE CLICK TO RESET)

• MATRIXES

• Innings (Showing both arrow for TOP and BOTTOM and innings number)

• Home Score (Max score is 29)

• Away Score (Max score is 29)

• Brightness for led strips (1 - 16) (When communicated to ScoreBoard it will be timed by 17 to move value to 0 - 255)

• Sample data
• #I=:1H= 0A= 0O=0B=032¤ (TOP first inning, Home 0, Away 0, Outs 0, Brightness 68)
• #I=;3H= 7A= 3O=2B=032¤ (BOTTOM third inning, Home 7, Away 3, Outs 2, Brightness 68)
• #I=:5H= 9A= 4O=1B=032¤ (TOP fifth inning, Home 9, Away 4, Outs 1, Brightness 68)
• #I=;9H=16A=10O=3B=032¤ (BOTTOM ninth inning, Home 16, Away 10, Outs 3, Brightness 68) (Mapped from 4 in ScoreControl)

I have continued testing and on a Arduino UNO it works with my orignial program, the rewritten one and with a one where I tried to remove the zones and just use the displayText instead and not having zones.

But on the Arduino UNO WiFi Rev 2 card it will never display the right information in the last matrix of the chain...

But on the Arduino UNO WiFi Rev 2 card it will never display the right information in the last matrix of the chain

Just to be clear , do you mean matrix number 0 (first one nearest the arduino connection) or number 3 (further from the Arduino connection).

[Wettemark]

The matrix number 3.

Here is the pictures of how it looks like for me. One with the UNO and one with the UNO WiFi..

My question is why o why are you using this kind of displays if you need 4 digits ?

I really can't see what could be causing this. BTW, I see no 'Wifi' code in the code you posted, just straight out code to handle switches and the display.?

Have you tried one of the examples from the Parola library on the Uno Wifi board? Does it manage to display on the last module?
