Thanks. I guess my circuit looks OK then other than the pull-up. I'll try the 1k5 in place of the 2k2. I also thought the AVR may be bad. I tried two different chips (both ATMEGA 168). I'm using the STK500 as an external programmer. I get no connection to the AVR with the circuit shown above, which ...

Hi. Does anyone understand why I would only get 1.6V from this setup? If pin 7 (ATMEGA VCC) is disconnected I measure 5.2V but with the VCC pin connected, it drops to 1.6 so there is not enough voltage to run the microcontroller.
