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_numberChip pin number to be used for UART RTS
txd_pin_numberChip pin number to be used for UART TXD
cts_pin_numberChip pin number to be used for UART CTS
rxd_pin_numberChip pin number to be used for UART RXD
hwfcEnable 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_msmaximum time to wait for the data.
rx_datapointer 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
crCharacter 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
strNull terminated string to send.
