I'm having problems with using Arduino YUN PWM outputs.
I need 4 PWM outputs that generally have the same base frequency of around 10 to 20 Hz or so.
I'm using timer 1 (A-pin-9,B-pin-10,C-pin-11) and timer 4 (A-pin-13)
I get pins 9,10,and 13 PWM output working decent, but for some reason pin 11 PWM frequency is much much higher.
Pins 9,10,11 should be working off TIMER 1 which all use the same pre-scaler, so I dont know how 9 and 10 can have one frequency, and 11 have a different frequency.
Here is my code can anybody see anything wrong? thanks!
#define PWM_4A_PIN 13
#define PWM_1C_PIN 11
#define PWM_1B_PIN 10
#define PWM_1A_PIN 9
void setup() {
TCCR1B = TCCR1B & 0b11111000 | 0x05;
TCCR4B = TCCR1B & 0b11110000 | 0x09;
analogWrite(PWM_4A_PIN,128);
analogWrite(PWM_1C_PIN,128);
analogWrite(PWM_1B_PIN,128);
analogWrite(PWM_1A_PIN,128);
}
void loop()
{
}
