Macro Definition Documentation

#define OPENWSN_UART_DEV ((STDIO_UART_DEV + 1) % UART_NUMOF)

OpenWSN default uart dev.

Note: If only one UART is available that uart might collide with STDIO_UART_DEV, otherwise the next available UART will be used.

Definition at line 56 of file openwsn_uart.h.

#define STDIO_UART_DEV (UART_DEV(0))

UART device to use for STDIO.

Dont want to include the stdio header, so redefine the default value

Definition at line 43 of file openwsn_uart.h.

void uart_init_openwsn ( void )

Initialize OpenWSN uart.

This will initialize a uart device at STDIO_UART_BAUDRATE/8N1. It will also initialize a timer to set sw tx_isr.

uint8_t uart_readByte ( void )

Reads a single byte received through uart.

OpenWSN will call this thrpugh uart_rx_cbt.

void uart_setCTS ( bool state )

Sets software flow control CTS.

This function sends XON or XOFF bytes to "set" or "unset" CTS by sw.

Parameters

[in] state true sets CTS, false clears CTS
