esp-hub75

Drive HUB75 displays from ESP32 series SOCs.

All implementations use DMA where supported.

• [ ] - documentation!
• [x] - LCD peripheral (async) for: esp32s3
  • [ ] - sync support for LCD peripheral
• [x] - I2S peripheral in LCD mode: esp32
• [x] - PARL_IO peripheral: esp32c6
  • [ ] - sync support for PARL_IO peripheral

Notes

• To drive HUB75 displays reliably you need a level converter between the GPIOs and the HUB75!

Examples

esp32s3: lcd_cam

Will display a red/green/blue gradient on the top 24 lines and some rendering and refresh stats at the bottom. Expects a 64x64 matrix.

esp32c6: parl_io

Will display a red/green/blue gradient on the top 24 lines and some rendering and refresh stats at the bottom. Expects a 64x64 matrix.

esp32: i2s

Will display a red/green/blue gradient on the top 24 lines and some rendering and refresh stats at the bottom. Expects a 64x64 matrix.
