Interrupt-driven Software UART on STM32F3

This library uses Timer3 and GPIO port C pin 6 (tx) and pin 7 (rx).

Example (echo on serial terminal)

#include "SoftwareSerial.h"
int main(void)
{
	ssInit(9600);         // Initialise software UART and specify the baud rate
	while(1) {
		if(isRxAvailable()) {
			ssWriteByte(ssReadByte());
		}
	}

	return 0;
}
