The example program uses a PWM output to control a servo motor. The servo motor is a HiTEC HS0422
The PWM signals for the MBED-SDK and the Bambino line of microcontrollers are mapped to the following connector locations:
| PWM Signal | LPC4330 PIN NAME | BAM210E | BAM210 | BAM200E | BAM200 | Used for |
| PWM1 | P1_7 | J9-3 | J9-3 | S2-3 | S2-3 | Servo Control Signal |
The following schematic can be used to build the circuit with a BAM210E or BAM210.
Schematic for example 04-05
/*Program Example 4.5: PWM control to DC motor is repeatedly ramped
*/
#include "mbed.h"
PwmOut motor(PWM1);
float i;
int main()
{
motor.period(0.010); // set PWM period to 10 ms
while(1) {
for (i=0; i<1; i=i+0.01f) {
motor=i; // update PWM duty cycle
wait(0.2);
}
}
}
The following image shows the built circuit on a BAM210E.
