Organization Overview - esp-rs

January, 2023

This a collection of repositories from within the esp-rs organization that I feel are the main points of interest. I've included any ongoing projects as much as possible.

A repository be omitted from this list does not mean that it is not important or useful, only that it requires much less development effort than other projects.

HARDWARE SUPPORT

• https://github.com/esp-rs/embedded-svc

std

• https://github.com/esp-rs/esp-idf-hal
• https://github.com/esp-rs/esp-idf-sys
• https://github.com/esp-rs/esp-idf-svc

Current Projects:

• Add support for new devices
• Slim-down: only pay for what you use: i.e. if I only use e.g. the ESP IDF HAL drivers and don't use STD (posix, LwIP networking, event loop), I should get a much smaller firmware size. Not sure that's the case right now? ESP IDF is kind of going in that direction recently, I think
• Mix and match esp-* (the no_std ecosystem) with esp-idf-* (the std ecosystem); possible? hurdles? what is the gap?
• Async story:
  • Upstream the ESP IDF async support for the smol-rs crate ecosystem and for socket2 (networking)
  • Async story for the ESP IDF HAL drivers (spi, i2c, uart, etc.)
  • Make sure embassy works on top of the std stack
• ESP-IDF
  • More support for ESP IDF components that live out-of-tree (outside the ESP IDF repo)
  • Unclear: any outstanding build issues? Stuff that we want to improve in esp-idf-sys

no_std

• https://github.com/esp-rs/esp-pacs
• https://github.com/esp-rs/esp-hal
• https://github.com/esp-rs/esp-wifi

Current Projects:

• Add async support to esp-hal (no_std)
  • GitHub Project: https://github.com/orgs/esp-rs/projects/3
• Low-power/deep-sleep and ULP support in esp-hal
• Continue adding chip support to esp-wifi, improve quality and usability of library
• Implement IEEE802.15.4 suppport

TOOLING

• https://github.com/esp-rs/espflash
• https://github.com/esp-rs/espup

Current Projects:

• Release new major versions, cargo-espflash@2.0.0 and espflash@2.0.0
  • Milestone: https://github.com/esp-rs/espflash/milestone/1
  • This is currently in the release candidate stage, with 2.0.0-rc.3 being the most recent version
  • Other than fixing a few small bugs I think this is quite close to being complete
• Stabilize and generally improve espup
  • Add a feature to allow installing standalone components like ESP-IDF Windows drivers
  • Add support for new devices
• ???

DOCUMENTATION

• https://github.com/esp-rs/book

Current Projects:

• Overhaul the book; better organization, add additional and more clear information
  • Tracking issue: esp-rs/book#59

I think we also want to look into ULP and LP support in esp-hal

For espup we currently are trying to stabilize/improve it and I'll be trying to add some features to make it able to install other standalone components like esp-idf and Windows drivers. And, of course, I'll be adding new chip support.

@MabezDev thanks, added.

@bjoernQ yup you're right, you would think I'd remember that one given that I'm working on it 😁

@SergioGasquez thanks, updated!

Another bigger topic will be 802.15.4
