i have a problem with one of the ports on my atmega8.
i made a board for programming it as described on linuxfocus.org (basic 5 wire parallel port programmer cable connected to a Veroboard containing few resistors and capacitors and a test led connected to pin5 of the portc like this
the problem is that when i upload .hex file in it (using avrdude, i get the ok code verification)
the pin 5 on PORTC wont strobe, although resistor connected to LED is a bit high for this circuit, light of the led when it glows connected to other pins is a bit dim, but still visible, so the problem is not in the value of the resistor)
testcode is standard led blinker:
DDRC = 0xFF;
so, all pins are strobing (measured voltage changes with multimeter) except for pin 5, i looked at the spreadsheet for this uC, but it didnt mention any oddities on this pin.
i managed to blink the led when i shortcircuited pin with pin 4 (or any other) of the same port, but thats not it.
im banging my head over this for few hours, but don't see what could be the problem.
btw i checked solder connections, there are no short circuits, and connections are fine.
