Two questions regarding analog comparator The alternate port function for PE2 is Analog Comparator Positive Input (surprise??!!).
Someone with a bigger brain than me maybe can explain why 1.85V is the "normal" value to be...

Two questions regarding analog comparator Quote:Does that mean that the PORTF and the "JTAG Pins target device" is basicly the same port? Could I connect the "stk600 JTAG programmer signal" to the PORTF instead? No, only...
Really weird counter glitch
in Temp, TCNT0
out TCNT0, Temp
out PortB, Temp
maybe should be
in Temp, TCNT0
out PortB, Temp
Which would load the value of TCNT0 on PortB.

Really weird counter glitch Btw, writing comments is an essential part of writing code.
As it look now, no one else but you have a clue what you really want to happen in that code line.

Really weird counter glitch You're actually loading the SRAM address for TCNT0 into Temp doing this
problem:
ldi Temp, TCNT0
Don't know what number you intend to load into Temp, but probably not SRAM...

If you're familiar with the program inside mega32 you can change the code to simulate card data and send that to MAX232.

Never used 128RFA1, does it possibly have JTAG pins on PORTE? If so disable JTAG fuse.
This sound as a suspicious JTAG issue, those pins are used i.e. for mega164. Disable JTAG fuse and see if that helps.
I'm pretty sure MBedder want you to use either a 1K pot or a 2K pot and sweep it from end to end.

I thank you both for your assuring answers.
