• New release: 5.1.2

Past events

• 16th November - code::dive - Wrocław - AeroRust talk featuring Rust Board - watch recording

Wokwi

• add GDMA support ESP32 S3 / C3 / C6 / H2

Experiments

• esp32-conways-game-of-life-rs - Rust Bare Metal Conway's Game of Life for ESP32-S3-BOX - added DMA for the display
• esp32-spooky-maze-game - release v0.9.0
  • added improved DMA for the display based on bjoernQ/rust-esp32s3-ili9341
  • confirmed I2C issue for ESP32-C3-DevKit-RUST, similar issue
    • problem: randomly failing read of IMU, probably interference when anything is connected to GPIO 8
    • workaround: decrease I2C frequency to 2 kHz
• esp32-buddy-rs - add snow simulation for ssd1306
