Detailed Description

Simple UART driver.

Function Documentation

void simple_uart_config	(	uint8_t	rts_pin_number,
		uint8_t	txd_pin_number,
		uint8_t	cts_pin_number,
		uint8_t	rxd_pin_number,
		bool	hwfc
	)

Function for configuring UART to use 38400 baud rate.

Parameters

rts_pin_number	Chip pin number to be used for UART RTS
txd_pin_number	Chip pin number to be used for UART TXD
cts_pin_number	Chip pin number to be used for UART CTS
rxd_pin_number	Chip pin number to be used for UART RXD
hwfc	Enable hardware flow control

uint8_t simple_uart_get

(

void

)

Function for reading a character from UART. Execution is blocked until UART peripheral detects character has been received.

Returns

cr Received character.

bool simple_uart_get_with_timeout	(	int32_t	timeout_ms,
		uint8_t *	rx_data
	)

Function for reading a character from UART with timeout on how long to wait for the byte to be received. Execution is blocked until UART peripheral detects character has been received or until the timeout expires, which even occurs first.

Returns

bool True, if byte is received before timeout, else returns False.

Parameters

timeout_ms	maximum time to wait for the data.
rx_data	pointer to the memory where the received data is stored.

void simple_uart_put

(

uint8_t

cr

)

Function for sending a character to UART. Execution is blocked until UART peripheral reports character to have been send.

Parameters

cr	Character to send.

void simple_uart_putstring

(

const uint8_t *

str

)

Function for sending a string to UART. Execution is blocked until UART peripheral reports all characters to have been send. Maximum string length is 254 characters including null character in the end.

Parameters

str	Null terminated string to send.
