PWM signals, atmega328p, but then on PD3 --> PIN5

Back to the system:


https://wiki.freepascal.org/AVR_Embedded_Tutorial_-_Analog_Write

Code: Pascal  [Select][+][-]

1.   var
2.    i : integer;  // Loop counter
3.  begin
4.    // Configure PD5 and PD6 as outputs
5.    DDRD := %01100000;
6.  
7.    // Configure PD5 and PD6 in PWM mode
8.    TCCR0A := (%10 shl COM0A) or (%10 shl COM0B) or (1 shl WGM0);
9.  
10.    // Enable timer 0, clock / 1024
11.    TCCR0B := TCCR0B or %101;
12.  
13.     OCR0A := 100;
14.     OCR0B := 100;

Can somebody help me out changing this for the Atmega328p controller, for PD3 --> PIN5

that would be a great help, Wouter van Wegen, PascalByThree

I assume you are referring to IO pin D3? That is controlled by timer 2 channel B.
Untested code adapted from the wiki example:

Code: Pascal  [Select][+][-]

1.    // Configure PD3 as output and preserve state of other pins
2.    DDRD := DDRB or  %00001000;
3.  
4.    // Configure PD3 PWM mode
5.    TCCR2A := (%10 shl COM0B) or (1 shl WGM0);
6.  
7.    // Enable timer 0, clock / 1024
8.    TCCR2B := TCCR2B or %101;
9.     OCR2B := 100;
10.  

In the attached picture you can see that output compare of timer two, channel B (OC2B) is routed to PD3.

i greatly thank, you it got to work !
