void rs232_init ( void )

Initialize the RS232 module.

This function is called from the boot up code to initalize the RS232 module.

Definition at line 50 of file rs232.c.

void rs232_print ( char * text )

Print a text string on RS232.

Parameters

str	A pointer to the string that is to be printed This function prints a string to RS232. The string must be terminated by a null byte. The RS232 module must be correctly initalized and configured for this function to work.

Definition at line 65 of file rs232.c.

void rs232_send ( char c )

Print a character on RS232.

Parameters

c	The character to be printed This function prints a character to RS232. The RS232 module must be correctly initalized and configured for this function to work.

void rs232_set_input ( int(*)(unsigned char) f )

Set an input handler for incoming RS232 data.

Parameters

f

A pointer to a byte input handler

        This function sets the input handler for incoming RS232
        data. The input handler function is called for every
        incoming data byte. The function is called from the
        RS232 interrupt handler, so care must be taken when
        implementing the input handler to avoid race
        conditions.

        The return value of the input handler affects the sleep
        mode of the CPU: if the input handler returns non-zero
        (true), the CPU is awakened to let other processing
        take place. If the input handler returns zero, the CPU
        is kept sleeping.

void rs232_set_speed ( unsigned char speed )

Configure the speed of the RS232 hardware.

Parameters

speed

The speed

        This function configures the speed of the RS232
        hardware. The allowed parameters are RS232_19200,
        RS232_38400, RS232_57600, and RS232_115200.
