Need help for wiring a specific Esp32-s3 controller #697

Open romain-granai opened 1 day ago

romain-granai commented 1 day ago

Hi, I'm not really sure it's the right place to ask but I'm kind of desperate. I have a Esp32-s3 Pico and a 64x64 led matrix, respectively: https://www.waveshare.com/esp32-s3-pico.htm https://www.waveshare.com/rgb-matrix-p2-64x64.htm those exact models.

I'm unable to find the correct wiring, strictly unable to find the correct wiring for my controller. Is that even possible? there is this:

https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA/blob/master/src/platforms/esp32s3/ReservedPinsForPSRAM.PNG

But that doesn't really help. Can someone just show me THE correct way (and I guess only way) of wiring the 16 pins to the correct GPIO?

Any help would be greatly appreciated.

Default pin mapping for this library for an ESP32S3 device is contained within:

https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA/blob/master/src/platforms/esp32s3/esp32s3-default-pins.hpp

Has the pin mapping so you just connect the HUB75 Pin (i.e. G1) to the relevant pin on the wave share board (it's GPIO 5 on the waveshare board for the RGB Panel's G1).

However, I see from looking at the waveshare board photo there's no GPIO 3 which the library uses for the 'C' HUB75 pin, so you will need to adjust the gpio mapping for gpio c using the mxconfig variable. Perhaps use GPIO 17 ('GP17') on the waveshare board.

Check the examples for how to do this.
