Module stm32f1xx_hal::gpio

General Purpose I/Os

Interfacing with v1 traits

embedded-hal has two versions of the digital traits, v2 which is used by this crate and v1 which is deprecated but still used by a lot of drivers. If you want to use such a driver with this crate, you need to convert the digital pins to the v1 type.

This is done using embedded-hal::digital::v1_compat::OldOutputPin. For example:

let nss = gpioa.pa4.into_push_pull_output(&mut gpioa.crl);
let mut mfrc522 = Mfrc522::new(spi, OldOutputPin::from(nss)).unwrap();
