Thanks for the suggestions about the atmega8515 - unfortunately it has to be a straight plug-in replacement. I am not allowed to touch the code (even assuming the correct source version could be located...). As an aside, there are actually two completely different pieces of hardw

Hi again, oops, it miss it again: it is exactly the opposite. CKSEL[1:3] programmed (= 0) => internal oscillar 1 MHz CKSEL[1:3] unprogrammed (= 1) => external crystal 8 MHz sorry, this inverse logic is quite error prone. beware your programmer, if it's a GUI, the box check could

I'm having some problems with my Mega8's serial port or crystal. It's programmed to use 9600 baud, but seems to transmit at 1200 baud. Either I'm not doing something correctly (likely) or the Mega8 is running at 1/8 speed. It's an 8Mhz crystal and the fuses that are set are: CKSE

For transmitting data from an AVR, the data needs to amplified. The current coming out a single port pin is not enough to drive an infraRed LED. To boost the signal, I've had success with a ULN2003a chip. Do a Google search for a chip's datasheet in PDF for more info. The infra r
