Code for driving HUB75-style RGB LED matrices, targeted at 32-bit MCUs using brute-force GPIO (that is, not relying on DMA or other specialized peripherals beyond a timer interrupt, goal being ...

C Library The underlying C library is focused on driving the matrix and does not provide any drawing operations of its own. That must be handled by higher-level code, as in the Arduino wrapper which ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and WiFi — are all ...
