Hi!
I'm trying to use the example panel from the library.I'm having some problems.

Here is the result that I see.
Controller stm32f103c8

[kalyan-m25]

I'm sorry, but when I opened the line

//enableDebugPorts();
I saw a beautiful firebird.

[kalyan-m25]

The problem was my carelessness! The Firebird is amazing!!!!

I have another P4 64x32 panel with fm6363 and tc7262 chips. here's the example I'm uploading

not a single pixel doesn't work.What am I doing wrong?

Hi
For FM6363 driver you have to use a DMD_RGB_FM6363 class instead of DMD_RGB

[kalyan-m25]

DMD_RGB <RGB64x32plainS16,COLOR_4BITS_Packed> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

does this line need to be changed to this?

DMD_RGB_FM6363<RGB64x32plainS16,COLOR_4BITS_Packed> dmd(mux_list, DMD_PIN_nOE, DMD_PIN_SCLK, custom_rgbpins, DISPLAYS_ACROSS, DISPLAYS_DOWN, ENABLE_DUAL_BUFFER);

#include "DMD_RGB_FM6353.h"-Leave it the same? Do I understand correctly?
in this case, the panel is still not working. Not a single pixel glows.

[board707]

in this case, the panel is still not working.

After changing the class to DMD_RGB_FM6363 your code looks correct. I see nothing that can prevents the panel working.

Perhaps it is a memory issue? Could you replace a bitmap code to pixel by pixel writing?

the panel is still not working

[board707]

The only that I can to suggest - the adding a 3.3 -> 5v level shifters. But it is weird that the panel not works without that.

[kalyan-m25]

It's a good idea, I'll definitely try it. I have another P6.67 48x24 panel with exactly the same set of FM6363 and SM16208 chips. It doesn't work exactly the same way. not a single pixel does not glow. maybe these chips need at least 5 volts.

[kalyan-m25]

I used 3.3->5 volt blood converters. Unfortunately, the result is the same. The panel doesn't work. Not a single pixel lights up.

[kalyan-m25]

I decided to use a different board based on the stm32f401rct6. but there was a problem with compilation.

It looks like you use incorrect STM32 Arduino support package

[kalyan-m25]

This is my first time using a stm32f401 board. Which package should I use?
