Simple ESP32-HUB75-MatrixPanel-I2S-DMA Test with PlatformIO

This is a quick test sketch for ESP32-HUB75-MatrixPanel-I2S-DMA.

Open using PlatformIO. Look it up and use it, it's a huge improvement over the basic Arduino IDE.

I bought this 64x32 panel and this ESP32 (ESP32-CH9102X) closely researching specifications. As of now everything seems to work fine. Manual wiring is a nightmare though, get a wiring PCB asap.

It currently draws a maximum of 1.4A at 5V, dropping lower to 0.5A with fewer LEDs and 0.06A with no LEDs shown.
