Buffered Serial Port Driver for RTOS

  • ISR driven, ring buffered IO operation
  • IO operations are idle waiting, don't waste time in RTOS :D
  • Can use external buffers
  • Based on mbed RawSerial

Example

SerialDriver Example

#include "SerialDriver.h"

SerialDriver pc(USBTX, USBRX);

int main()
{
    // setup serial port
    pc.baud(9600);
    
    // print some text
    pc.puts("This is just a string.\r\n");
    pc.printf("But this is a %s with integer %i and float %f.\r\n", "formatted text", 123, 0.456f);
    
    // now lets behave like a null modem 
    while(1)
       pc.putc(pc.getc());
}

Look at the API Documentation for more Examples.
