Module stm32l0x1_hal::serial

USART(s) and LPUART

This is an implementation of RS232 USART(s) and LPUART. The interface for the LPUART and USARTs is largely the same, though their interaction with various power modes is different (see the Reference Manual).

let mut flash = d.FLASH.constrain();

let clk_ctx = rcc.cfgr.context().unwrap();

let mut gpiob = gpio::B::new(d.GPIOB, &mut rcc.iop);

// VCP USART
let vcp_rx = gpioa.PA15.into_output::<PushPull, Floating>().into_alt_fun::<AF4>();

let vcp_tx = gpioa.PA2.into_output::<PushPull, Floating>().into_alt_fun::<AF4>();
vcp_tx.set_pin_speed(PinSpeed::VeryHigh);
