however, the output compare match will generate the waveform on OC0A pin, which is in this case, PB4
so in order to let the signal visible on the pin (output), i put this line in

DDRB = 0x10;

but i kinda have a situation here, cos im attaching the butterfly on my school's development board and it does not give any access to portB
so my question is, how do i write the code to let, say Port D Pin 0 (PD0) to output whats on PB4?
many thanks in advance

while in fastPWM avr count up and down and both time when compare occurs state of Output compare pin changes. If you enable the compare interrupt then you can change the state of PortD0 pin in that service routine. try it..]]> Ajay<contact@nospam.com> Thu, 24 Apr 2008 08:39:24 -0700 http://www.8051projects.net/forum-t8953.html http://www.8051projects.net/forum-t8953.html but this one is more clear i guess
i'll try to do it first and see what happens
thanks!
