I need four Fast PWM signals for four different transistors.

I want to use timers 1+2 (pins 3, 11, 9, 10) so it wouldn't interfere with delay(...).

I tried setting the timers to Fast PWM mode, and applied different OCRnA/OCRnB values, but nothing really worked - at most, I managed to get two good PWM signals, one from each timer.

How should I deal with TCCRnA/TCCRnB, OCRnA/OCRnB to acheive 4 parallel PWM signals?

My latest attempt:

    // Timer 1 Fast PWM setup: TOP=0x00FF, Update of OCRx at BOTTOM (0), TOV Flag Set on TOP
    pinMode(9, OUTPUT); pinMode(10, OUTPUT);
    TCCR1A = _BV(COM1A1) | _BV(COM1B1) | _BV(WGM10);
    TCCR1B = _BV(WGM12) | _BV(CS11) | _BV(CS10); // Divisor 64
    
    // Timer 2 Fast PWM setup: TOP=0xFF, Update of OCRx at BOTTOM (0), TOV Flag Set on MAX (0xFF)
    pinMode(3, OUTPUT); pinMode(11, OUTPUT);
    TCCR2A = _BV(COM2A1) | _BV(COM2B1) | _BV(WGM21) | _BV(WGM20);
    TCCR2B = _BV(CS22); // Divisor 64
 
    // ...
 
    int val = 200; // Desired PWM output
    OCR1A = val;
    OCR1B = val;
    OCR2A = val;
    OCR2B = val;
