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

Bare-Metal RUWM

Can we use RUWM as an ongoing litmus test for our bare-metal portfolio readiness?

Stuff that RUWM core would need to run on bare-metal:

• An executor - can be either embassy-executor or edge-executor (as ESP bare-metal has a generic allocator now) and we can make it configurable
• Blocking or async drivers for SPI, I2C, one-shot calibrated ADC and pin peripherals (pin peripherals need interrupt support)
  • Blocking drivers
    • ADC

• Need to implement calibration
