Alright. I built the addon power circuit. When power (About 4 volts) is applied to Pin 6 of the LPT port, I get a Nice 12.55 volts at Pin 1 of the AVR socket. (This was done with a battery pack, connected from Ground, and touching pin 6 of the LPT port, and having a meter on Pin 1 of the AVR socket, and ground.)
I have not tested that I am getting power OUT from the Computer on Pin 6 though,,,,, But I will, I tried just connecting everything and No Joy, Still get that error. And connecting the Atmel to my VP-280 it still says lock bits are set. It will not read the Chip.
I will need to probe a bit deeper on my PC That I have this home built Programmer connected to see if things are triggering like they should.
Not sure How long or "when" the reset should go to 12 Volts.
OK, I just checked the power.
These are checked at the AVR socket
I get 5.13V between pin 20 and Pin 10 (this is the power for the Chip)
I am getting 12.55 between Pin 10 and Pin 1 (I can change with the (M) on Keyboard) so the "toggle" is working. And it is powering it properly. I am going to assume that it IS working "in program" as when I click Program I see my meter change voltage several times during the cycle but it is quick, so no "good" read.
What am I missing?
