2 Clock signals

Other Hardware General Electronics

I've been using this code:

const double freq = 0.8 * 1.0e6; //in hertz
void setup() {
  
  TCCR2A = ((1 << WGM21) | (1 << COM2A0));
  TCCR2B = (1<<CS20);
  TIMSK2 = 0;
  OCR2A =  0.5 * (F_CPU / freq) - 1;
  
}

void loop() {
 
}

in order to get a 0.8 MHz signal out of pin 11 on my arduino UNO and its working great. However I need another clock signal so that its frequency will be 0.2 MHz. Is there a way to create two different clock signal from two different pins on an arduino UNO?

Thanks for the helpers

There are three timers. If you choose the right pins linked to the right timers then it should work.

In other words you need two different timers. Note that the three timers are all different,
timer1 is 16 bit, timer0 and timer2 are 8 bit. They are very similar, but different enough you'll
need to double check all the register details for each...

The Arduino Mega uses the ATmega2560 which has the same three timers plus three more 16
bit timers (all identical in function to timer1).
