Function Documentation

void uart_put

(

uint8_t

Execution is blocked until the UART peripheral reports that a character has been sent.

Parameters

[in]

cr

Character to send.

uint8_t uart_get

(

void

)

Reads a character from UART.

Execution is blocked until the UART peripheral detects that a character has been received.

Returns

cr Received character.

void uart_config	(	uint8_t	txd_pin_number,
