# ESP32 64x64 RGB DMD Driver This project drives a 64x64 RGB LED Dot Matrix Display (DMD) connected to an ESP32 using the HUB75 interface via a DMDos board. ## Hardware Setup - **ESP32** connected to the DMD via HUB75 port on DMDos board. - **Pinout** (as per DMDos board): - R1: GPIO 25 - G1: GPIO 26 - B1: GPIO 27 - R2: GPIO 14 - G2: GPIO 12 - B2: GPIO 13 - A: GPIO 33 - B: GPIO 32 - C: GPIO 22 - D: GPIO 17 - E: GND - CLK: GPIO 16 - LAT: GPIO 4 - OE: GPIO 15 ## Software - Uses the [ESP32-HUB75-MatrixPanel-DMA](https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA) library. - Displays vertical RGB bands for testing. ## Building and Uploading 1. Install PlatformIO. 2. Open the project in VS Code with PlatformIO extension. 3. Run `pio run` to build. 4. Connect ESP32 and run `pio run --target upload` to upload. ## Notes - If colors appear incorrect, you may need to swap pin assignments (e.g., R and B) depending on the panel's color order. - Adjust brightness with `setBrightness8()` if needed.# squareDMD
