stm32f072-hal
stm32f072rb-hal contains a hardware abstraction on top of the peripheral access API for the STMicro stm32f072 series microcontroller.
This crate is mostly a shameless copy of [stm32f042-hal][] crate with appropriate changes. Warning: added serial and spi ports weren't tested yet! Only mechanical changes in code were made
If you want a board to try this there is a nucleo-f072rb board on the market.
