• Available releases of ESP-IDF: 5.1.1, 5.0.3, 4.4.5, 4.3.5, 4.2.5
• Upcomming release of ESP-IDF: 5.0.4

Future Events

  • talk: Rust in the Industry – Secure and Sustainable Development

Past events

• Espressif DevCon 2023 - 12th-13th September - https://devcon.espressif.com/
  • Rust Bare-metal and Async - September 12, 17:00
• Rust embedded at Espressif @ Copenhagen Rust Community - recording from Scott's talk

Tooling

• Wokwi
  • Rust included on main page
  • Latest projects listed - Rust reached 1500+ projects
• JetBrains launched new IDE RustRover
  • works with espflash, just check option Emulate terminal in output console
• USB integration
  • we have option to use Beagle USB 480 to diagnose USB integrations for Rust, feel free to contact us with request to analyze USB communication in context of implmenting drivers for Rust on ESP32
  • example: ESP-IDF has working implementation with USB Modems

Experiments

• esp-workbench - (former esp-helm) PoC desktop app with Tauri - goal: easier navigation and boostrapping of development build environment
• esp32-spooky-maze-game - 0.6.0 updated to latest hal
  • removed unnecessary watchdog configuration
  • experimental implementation for ESP32-C3-LcdKit with gc9a01.rs - not working, only backlight turns on, no obious difference found when compared to C implementation. According IDF team following C implementation is fully functional.
• axp2101 - partially working PMU - power up the display on M5Stack-CoreS3

[ogoffart]

I'll join the meeting.
I'd like to propose the topic of Slint ESP-IDF integration

[georgik]

Thank you @ogoffart . That's interesting topic. BTW: we marked the component as featured, so it's displayed on the main page of https://components.espressif.com/
