Struct UART

pub struct UART { /* private fields */ }

This struct represents a configured UART peripheral.

Implementations

impl UART

pub fn new( core: u8, tx_pin: (char, u8), rx_pin: (char, u8), baud: u32, ) -> Result<Self, ProgError>

Configure a serial connection with one of the internal UART peripherals.

This Method expects the used UART core, two pin identifiers for the tx and rx-pins and a baudrate as parameters and returns the UART Struct. Panics if the core or pins are already used or invalid.

pub fn end(self)

Deacitivates the UART connection and destroys the struct, freeing the core and pins.

pub fn print_char(&self, data: char) -> Result<(), SerialError>

Sends an ASCII char over the serial connection. Returns an error-enum if problems with the connection are detected.

pub fn print_str(&self, data: &str) -> Result<(), SerialError>

Sends an ASCII string over the serial connection. Returns an error-enum if problems with the connection are detected.

pub fn println_char(&self, data: char) -> Result<(), SerialError>

Acts like print_char except it prints a newline at the end of the string.

pub fn println_str(&self, data: &str) -> Result<(), SerialError>

Acts like print_str except it prints a newline at the end of the string.

pub fn write(&self, data: u8) -> Result<(), SerialError>

Sends a raw byte over the serial connection. Returns an error-enum if problems with the connection are detected.

pub fn read_char(&self) -> Option<char>

Waits until it recieves an ASCII char. Returns an error-enum if problems with the connection are detected.

pub fn read_byte(&self) -> Option<u8>

Waits until it recieves a byte. Returns an error-enum if problems with the connection are detected.
