Support for Adafruit Feather M0 board about ada_drivers_library HOT 3 CLOSED

https://github.com/JeremyGrosser/clock3/tree/master/src

Before the RP2040 came out, I was working on drivers for the samd21 as a part of another project. It's in very rough shape and there are a lot of things in this repo not relevant to the samd21, but I figured I'd push what I have if it might be useful to others. Much of this code is incomplete or broken, but it does work well enough to use the UART and some I2C peripherals.

I was going for more of an Arduino-like experience with the Board package, rather than building drivers that implement the HAL interfaces. If you're developing a reusable set of drivers for this chip, a HAL compatible interface is definitely the way to go.

Hi @faelys

Is there any hope for an ADL newbie like me to add Feather M0 support?

There is hope :) It is indeed not an easy task, but you can do it.

I strongly recommend getting a good debugger setup, and for this the Feather M0 is not the best since there is no Cortex-M debug connector on the board.
The METRO M0 Express would be a better option: https://www.adafruit.com/product/3505

For the debugger you can either get a SEGGER J-Link EDU Mini (https://www.adafruit.com/product/3571) or Black Magic Probe (open source, open hardare): https://www.adafruit.com/product/3839 .

If so, would you have any specific advice for this hardware, or should I just proceed with reading the general documentation and > starting from the MicroBit support?

Nowadays I would look at what is done for the samd51 (myself) and the rp2040 (Jeremy Grosser) in the Alire ecosystem.

I started to write some instructions for you but it quickly turned in to a blog post. So stay tuned on AdaCore blog because I will post the instructions there ASAP.

Is there anybody else interested in this board who would spend time to work with me on this?

In theory I am, and I will help you as best as I can for the drivers. But I don't have much time available at the moment.

Hello @faelys,

The blog post is here: https://blog.adacore.com/starting-micro-controller-ada-drivers-in-the-alire-ecosystem

I hope this will help you getting started. I will close the issue for now. but don't hesitate to ask follow-up questions.
