Hello World!

Create a sawtooth wave

#include "mbed.h"

AnalogOut signal(p18);

int main() {
    while(1) {
        for(float i=0.0; i<1.0; i+=0.1) {
            signal = i;
            wait(0.0001);

Details

The AnalogOut Interface can be used to set the voltage on the analog output pin somwhere in the range of 0.0v to 3.3v. The 0.0v to 3.3v range of the !AnalogOut can be represented in software as a normalised floating point number from 0.0 to 1.0, or directly as volts or millivolts.
