Some time display going stuck

[maxmurugan]

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]

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

[maxmurugan]

this is p6 module using PICO board

[maxmurugan]

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]

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.

[maxmurugan]

please check

[board707]

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.

[maxmurugan]

thanks sir i will change this code and check

[maxmurugan]

this is copy past issue

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

Showing junk display at this time PICO Serial data received

[board707]

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.

[maxmurugan]

i am trying to find this bug ,every 2 to 3 hour create this issue

[maxmurugan]

please need help

every 1 hour, how to restart your library or Software restart for raspberry pi pico

how to restart your library or Software restart for raspberry pi pico

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

I completely remove DHT library code ,Now no error on the led display thanks for your support

I have another one question

i have custom led board 74 hc595 and uln2803 driver ic

1/2 scan method it is possible drive your library

16x48 pixel

[board707]

have custom led board 74 hc595 and uln2803 driver ic

Uln2803 driver? Are you sure? It is not common for LED panels using this driver. Is the panel has a HUB75 connector ? Please show the pictures

[maxmurugan]

it is old board design using railway application

[maxmurugan]

1 and 9 column connected 16x48 total 6 74hc595 ic 8 and 16 connected

tomorrow will send picture

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.
