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.
