Feature request - SPI

[Wratox]

Add support for the SPIx peripherals.

Might try to add this myself, but is there any reason to not go straight for embedded_hal v1.0.0?
If so do you think stm32-rs/stm32h7xx-hal#476 is a good place to start?

[astapleton]

@Wratox I have a SPI implementation already that implements Master + Slave + embedded-hal 1.0.0 that I will start putting up for review soon!

[Wratox]

@astapleton Alright, nice!

I did start on it and I did the pins for SPI for stm32h573, is that something you have a use for or have you already implemented that?

[astapleton]

@Wratox yes, that would be helpful. I don't have pins for anything other than the STM32H503 right now

[Wratox]

@astapleton It's available at spi.rs at my spi branch.
I also did the pins for stm32h523, there's a comment in the code about what datasheets I've mapped.

[tytouf]

@Wratox any progress on your side ?

I'm working on a board with an stm32h533 and would really like to use your code if it is available. Of course if it needs any testing or changes I can also contribute.

Thanks,

[astapleton]

@tytouf I've been working on the SPI when I have time. The latest version I've pushed is on https://github.com/stm32-rs/stm32h5xx-hal/tree/as/spi-master. I've made some changes since I published that, and I need to just find some time to test that it still works, but if you stick to the embedded-hal traits it should be good when it merges. I think once that is merged I can do some cleanup and publish to crates.io too.

[tytouf]

Thanks @astapleton I'll take a look.

PR is up: #53

[astapleton]

Reopened because I still need to put up the slave operation PR!

[astapleton]

@tytouf PR is up (#62) if you want to test it
