CH58X(CH582M) BLE Support

[andelf]

I need some time to look into it. I'll check it this weekend.

There are a few things that belong in the pac that were absent or buggy

Yes, their SVD files are very buggy. So they are patched with svdtools.
The CH58x.svd is not revised yet.

I'm not sure how licenses should work here. The rt steals some things from the wch repo, I don't think this is proper.

Since https://github.com/openwch/ch583/tree/main/EVT/EXAM/BLE/LIB is under Apache-2.0 license, make sure the libs/files you refer to are located in the openwch repo. Then it's OK to include them with a proper LICENSE.

ble doesn't work in the default riscv runtime

This should be fixed by pre_init hook. If not feasible, we can invent a -rt crate for CH58x.

As with pac v0.2.0 release, most issues are fixed.

Check out https://github.com/ch32-rs/ch58x-hal, I've referred a lot from your hal crate. This is an embassy-style hal crate with embassy time driver support.

Critical section works in the default riscv runtime, but not in my ble runtime.

Fixed in the ch58x-hal crate.

https://github.com/ch32-rs/ch58x-hal/blob/f3a25a2b6b66a26ec739197e00b81eaf7dd11aad/src/critical_section.rs#L6-L21

This seems to be related to the handling of "highcode",

Added highcode support in the crate, using link script and #[highcode] macro.

Currently, I'm trying to port the BLE rt to it. At lease the RF_PHY example works.

Update: BLE broadcaster and scanner now works.

Close as finished.
