Hi,
I have started on a rust HAL for the Ambiq + board support crate for Sparkfun Reboard Artemis. So far I’ve implemented a couple of pins and transitions, as well as UART (for USB-serial) and I2C.
It optionally uses the ambiq-sdk so you can fallback to the C hal for the parts that are not implemented yet.
