USB Support #1

Open nickray opened 5 years ago

nickray commented 5 years ago

The biggest problem moving this effort forward is the lack of an embedded Rust USB stack: https://github.com/rust-embedded/wg/issues/40

There is a port of @mvirkkunen's usb-device (implemented for stm32f103) to atsamd21, and another effort for stm32f0.

The goal is to have a clean, minimal Rust implementation, not a wrapper of an existing C implementation (e.g. the STMicroelectronics implementation or libopencm3). Studying https://github.com/dmitrystu/libusb_stm32 should prove helpful in finding all the details hidden "somewhere" in the datasheet and reference manual.

Toil and pain have resulted in Serial-over-USB working: https://github.com/nickray/stm32l43x-usbd
