Quick question; Is it safe to use the parallel port's supply to power an AVR?
I was just wondering whether you'd need a voltage regulator or not, and if it would harm the port.
Thanks

Re: DAPA cable
It seems I've made a silly mistake.
It's just that in AVRDude's config file - (/etc/avrdude.conf) - under the DAPA cable config it labels pin 3 as VCC.
Any ideas why?

Re: DAPA cable
I don't know anything about DAPA so I will sign off of this thread... You might post this in the Arduino forum if you are using it with Arduino.

Re: DAPA cable
One or more of the parallel port lines can be used to supply power to the chip being programmed.

oPossum: Would that voltage be safe to use with an AVR? (is it <5V?)
And also; thanks a lot for the schematic.
I think i'll end up testing it out either way.

Re: DAPA cable
parallel ports are exactly 5V

Ah, cool.
That makes things easier.
