This example outputs a saw tooth wave form on the DAC output. The DAC output is on pin A5 of J8.
DAC0 for the MBED-SDK and the Bambino line of microcontrollers is mapped to the following locations:
| Signal | PIN NAME | BAM210E | BAM210 | BAM200E | BAM200 |
| DAC0 | P4_4 | J8-6 | J8-6 | S3-5 | S3-5 |

*/
#include "mbed.h"
AnalogOut Aout(DAC0);
float i;
int main()
{
while(1) {
for (i=0; i<1; i=i+0.1) { // i is incremented in steps of 0.1
Aout=i;
wait(0.001); // wait 1 millisecond
}
}
}
The following image shows the circuit in action.
