Hi everybody,
Forgive me if this was discussed earlier, I couldn't find anything about it. I am planning to use DUE to drive 4 pololu dc motors via VNH5019 motor driver. Pololu has a library to drive the motors however it needs to be edited because maximum 2 motors can be driven with the library since a timer cannot be used with more than 2 pwms.
The below code section assigns the 1st timer to pins 11,12 or 13. For Arduino Due, how should the below code be in order to assign a timer to a specific pwm pin?
if(_PWM1 == 11 || _PWM1 == 12 || _PWM1 == 13 ||
_PWM2 == 11 || _PWM2 == 12 || _PWM2 == 13)
{
//timer1
TCCR1A = 0;
if(_PWM1 == 11) { TCCR1A |= _BV(COM1A1); _PWM1_REG = &OCR1A; }
else if(_PWM1 == 12) { TCCR1A |= _BV(COM1B1); _PWM1_REG = &OCR1B; }
else if(_PWM1 == 13) { TCCR1A |= _BV(COM1C1); _PWM1_REG = &OCR1C; }
Thank you,
Mr. Kaan Yilmaz
