ICMD2153 P2.5 128x64 partially working

[VinzRep]

Hello,

First of all, thank you a lot for amazing job of this lib.

I got a problem with my matrix : First 48px not working correctly, but the last 80px are OK:

• First 32px have fixed white leds, and text scrambled even if it should not be there, on the same line than text displayed on other column.
• Next 16px : when text there, it is a little scrambled.

Any idea what's happen ?

Matrix : ICMD2153 P2.5 128x64
Controler : STM411CE Blackpills
Lib : DMD_STM32 [v1.2.4]
Code : "dmd_spwm_panel" example with "DMD_RGB_FM6353" uncommented line and text "Hello Word!".

Hi
Thanks for the response.
Interestingly, when trying to port the FM6353 driver code from the STM32 to the RP2040 boards, I'm having exactly the same problems as you're seeing in the picture. Unfortunately, I haven't been able to solve them yet.

However, everything works reliably on the STM32F4 for me. Perhaps using 3v3->5v logic level converters will help you. Although, I must say, I don't have high hopes for this.

I'm currently on vacation and will continue working on this code after January 10th.

Happy New Year.

Hi

The sPWM drivers code (including ICND2153) has been partially rewritten in the new version. This may solve your problem.
Please test a new release https://github.com/board707/DMD_STM32/releases/tag/v1.2.5
