hi sir,

P6 RGB or P10 Red color module display issue showing at the same time serial port data send receiving working

please check picture.

after poweroff and on going to normal mode ,how to solve this issue

board707 commented 1 year ago

Sorry, I don't understand. Please explain more clearly, what is a problem

maxmurugan commented 1 year ago

this is p6 module using PICO board 17560

maxmurugan commented 1 year ago

working fine after few hour display showing garbage please check video.

https://github.com/board707/DMD_STM32/assets/4962604/797d4938-7323-412a-8c12-5b2e466a39c0

At the garbage time Restart the controller going to normal working

same issue I will face p10 red color module.

board707 commented 1 year ago

Good afternoon Too little information to give advice This behavior can be caused by many reasons - errors in the code, power problems, some kind of electromagnetic interference. For example, one of the options is memory problems in the library code or in the main program. Could you please provide a example code, where the problem is observed.

board707 commented 1 year ago

I am not sure is this a cause of the problem or not, but there are errors in the code. At the end of the loop()

dmd.drawString(17,0,a,sizeof(a),col[1]);

The using of sizeof() is incorrect in this case, it returns the size of array rather than a length of string. Use the strlen() instead:

dmd.drawString(17,0,a,strlen(a),col[1]);

There are a several lines with the same error.

Next, these two methods are wrong:

byte decToBcd(byte val)
{
return ( (val/1016) + (val%10) );
}
byte bcdToDec(byte val)
{
return ( (val/1610) + (val%16) );
}

Since the calculation is carried out in integers, the first expression, (val/1610), is always zero and whole result will be val % 10 in first function and val %16 in second.

thanks sir i will change this code and check

Showing junk display at this time PICO Serial data received

board707 commented 1 year ago

Sorry but your code seems to have a some errors:

What are you try to achieve in this line?

 if((Adjust_Temp/1000)== '+')   {

your Adjust_Temp is integer, comparing it with char not making sense for me

This line is not the one with errors...

If you find a bug in a library, please prepare a short code example where the bug appears. I don't have the ability to run your entire project with modbus, serial and sensors.

Hi To soft restart a Pico board you can use a watchdog feature: https://github.com/raspberrypi/pico-examples/blob/master/watchdog/hello_watchdog/hello_watchdog.c

total 6 74hc595 ic

It seems to me that for 16x48 panel it should be 12 74hc595 ic in total.

What for do you plan to use this panels? Without major code modification, they will not work with this library. I could add support for these panels to the code if I had them available. Without panels for tests, this is hardly possible.

Why would you like to use exact this panels? Do you have dozens or hundreds? Apparently, this is a very old design and it is unlikely that anyone will actively use them. If you have only a few panels, it is hardly worth spending so much effort on them, it is more profitable to buy modern ones.

ok thanks
