Does Matrix Portal M4 support panels with FM6126A chip?

Post by dougiejones »

I have a couple of panels that run fine with the SmartLed shield (https://www.adafruit.com/product/1902), but both refuse to work with MatrixPortal. Any way to make them work? Thanks!

Both boards work with HUB75 panels. If they are HUB75 panels, they should work with the MatrixPortal.

Please explain what you mean by "refuse to work".

Heh. "refuse to work" == "the program is running, but the panel is completely blank". I suspect the FM6126 chip is not supported by rgbmatrix/protomatter.

Perhaps not. What panels do you have?

For what it's worth, SmartMatrix library (which works) has this:

Code: Select all

                    // experimental FM6126A support on ESP32 without external latch: make LAT pulse 3x clocks wide, matching the FM6126A "DATA_LATCH" command (and not the "RESET_OEN" command)
                    if(optionFlags & SMARTMATRIX_OPTIONS_FM6126A_RESET_AT_START) {
                        if((refreshBufferPosition) == PIXELS_PER_LATCH-2) v|=BIT_LAT;
                        if((refreshBufferPosition) == PIXELS_PER_LATCH-3) v|=BIT_LAT;
                    }

OK, so they are essentially an unknown. Have you tried getting the SmartMatrix library working on the MatrixPortal?

Regrettably, no. SmatrtMatrix seems to support only Teensy and ESP32.

yeah we dont own or sell any of those chip panels - if you're able to add FM6126 to protomatter we'd gladly take a pull request!
