Tracking the "next" project

[jessebraham]

This work is inspired largely by the same effort already undergone in esp-idf-hal, which in turn was based on the work done in embassy.

https://github.com/esp-rs/esp-idf-hal
https://github.com/embassy-rs/embassy

Development will be done in the next branch. I have added a single commit which adds some types, traits, and macros which will be required for development.

https://github.com/esp-rs/esp-hal/tree/next

This branch will be periodically rebased on main to keep it in sync as much as possible. As we're able we can merge changes into main, repeating this until the process is complete.

A number of peripherals will need their high-level interfaces re-written, though we can likely take this directly from esp-idf-hal with only minor modification. Hopefully most of the low-level code can be kept and/or adapted.

Tasks

The tasks below do not need to be completed in any particular order.

If you plan to implement the necessary updates for a peripheral please leave a comment below indicating such.

• LEDC (PeripheralRef: LEDC #307)
• MCPWM (PeripheralRef: MCPWM #314)
• RMT (PeripheralRef: RMT #310)
• RNG (Peripheral ref/rng #306)
• RTC (PeripheralRef: RTC #319)
• SHA (Peripheral ref/sha #312)
• SPI (PeripheralRef/spi #299)
• SYSTEM (PeripheralRef for SYSTEM/DPORT #305)
• SYSTIMER (Peripheral ref/systimer #302)
• TIMG (PeripheralRef: TIMG #320)
• TWAI (Initial TWAI Driver Implementation #192)
• UART (PeripheralRef init: uart #272)
• USB_OTG (PeripheralRef: USB_OTG #318)
• USB_SERIAL_JTAG (Peripheral ref/usb #304)

I have previously done some work on both the UART and GPIO modules, and will get both projects cleaned up and pushed to branches soon.

[jessebraham]

With #272 merged we have all the required building blocks to move forward with this, plus a UART implementation for reference.

For reference: #299 is a good example what needs to be done to convert a peripheral driver to the use the PeripheralRef pattern

no idea what to do about TWAI since it's not merged yet 🤷‍♂️

[bjoernQ]

Looking into GPIO

@MabezDev will take over 🙏

I am going to try and get a test project set up for this next week so that we can get that PR merged.

[jessebraham]

Have I missed any peripherals in the first post? I will go through the code base later, but wouldn't mind some more eyes on it just to be sure. Pretty sure I got everything, but who knows 😁

[jessebraham]

TWAI PR has been merged, so I suppose we're done here 😁 Thanks for the help everybody!
