Areas

Items marked with exclamation marks❗❗are priorities for Q4.2023
Items marked with ⏳ are Open.

Architecture / Refactoring

1. Unifying esp-hal into one package (instead of having esp32-hal, esp32-c3-hal,…)
   • RFC: Unify the HAL esp-hal#446 ⏳

Bare metal

1. ❗Async support esp-hal❗
   • Implement async support for all applicable peripheral drivers esp-hal#361 ⏳
2. IEEE 802.15.4
   • Needs to be tested and we add support for OpenThread
3. BLE
   • Bluetooth support for all chips esp-wifi#93 ⏳
   • ESP32-C6 is supported , only missing support for ESP32-H2

CI

1. Running tests on real HW
   • Check status with Jesse
   • Jesse wants to implement test framework

Documentation

1. esp-wifi documentation
2. Expand no_std training book
3. Documentation - general discussion of plan. #742

espflash

1. Using parts of espflash library in esptool.js
   • https://github.com/rustwasm/wasm-pack
   • https://github.com/rustwasm/wasm-bindgen

Logging

• Nothing

Low-power

1. ❗RISC-V ULP❗
   • Add support for the RISC-V ULP esp-hal#377 ⏳
2. ❗Light/Deep sleep modes❗
   • Implement support for light-/deep-sleep esp-hal#375 ⏳
   • Modem sleep

New Chip Support

1. ESP32-P4
   • Preview-support in ESP-IDF v5.2
2. ESP32-C5
   • Supported in ESP-IDF v5.3

Real Time Operating Systems (RTOS)

1. RTIC is adding support for ESP32-C3

Research

1. R&D: Investigate using heterogenious lists for ideal resource management workflow#789

STD

1. Support for the Thread protocol
   • Not clear what needs to be done here... ESP IDF already supports the OpenThread C API; seems baremetal is converging towards OpenThread as well; need to research whether there are good, safe bindings for OpenThread in Rust

Xtensa

1. Upstreaming Rust patches once LLVM patches are in experimental target
   • Tracking Issue for merging to upstream (LLVM-57) espressif/llvm-project#4 ⏳
2. Tooling: lld
3. probe-rs support - dependency of Running tests on real HW (CI area)
