Pull Request Details 📖

Split out of #4604.

This changes tx and rx methods to require PulseCode instead of supporting impl Into<PulseCode> and impl From<PulseCode>, respectively.

Supporting these traits has probably had limited value, was only added (by me) very recently, and removing them prepares for supporting more general data types (#4604 or whatever alternative turns out to be a better design).

This was also suggested by @bugadani in #4126 (review).

Testing

HIL tests.

Pull request overview

This PR simplifies the RMT (Remote Control) peripheral API by removing generic type support from transmission and reception methods. The change requires buffers to contain PulseCode directly rather than supporting arbitrary types through Into<PulseCode> and From<PulseCode> trait bounds.

Key Changes:

• Removed generic type parameters from TxTransaction and RxTransaction structs
• Updated all TX methods to accept &[PulseCode] directly instead of generic impl Into<PulseCode>
• Updated all RX methods to accept &mut [PulseCode] directly instead of generic impl From<PulseCode>
