Jtag read voltage out of range
I could try replacing the input protection myself. May I ask what you did with your device? That one you can easily get the chip. As a last resort you can just de-solder the...

A character LCD does not display - AtMega32
Had I seen that I would not care at all either.

A character LCD does not display - AtMega32
So what does it show on page 6??

Show us the datasheet for you LCD, it will tell you there, it is usually connected to a pot (10K?) so that you can adjust the contrast.

Jtag read voltage out of range
If you can try with another debugger and it all works you may have blown the input protection chip just behind the socket for the JTAG cable, it happened to me once.

Is VEE really connected to V+?? It's normally very close to ground but yours may be different.

Xmega and Zener Diode advice
i think a voltage divider circuit could work. A 3K to ground and a 2K from the input will give you the exact 5V to 3V translation if that's all you need.

Chip suggestions with large number of I/O
The biggest AVR or Xmega is a 100 pin device. ie ATmega2560 or Xmega128A1U or maybe others.

Xmega and Zener Diode advice
Low voltage zener diode are a very bad choice as they need some minimum current to work well or they will clamp your voltage below their rated voltage.   A series resistor...

No really but you have a split post here   So I will lock this thread to avoid people responding to more than 1 thread and getting annoyed.

George you are asking help from threads that are many years old and the people are not around anymore. This thread is 12 years old.
