stm32f767-hal
stm32f767-hal contains a hardware abstraction on top of the peripheral access API for the STMicro STM32F767 series microcontroller.
This crate relies on my stm32f7 crate to provide appropriate register definitions and implements a partial set of the embedded-hal traits.
There's a ready-made eval board I can recommend with the nucleo-f767zi on the market which even features built-in Ethernet.
Some of the implementation was shamelessly adapted from the stm32f103xx-hal crate by Jorge Aparicio.
