Yes, Avrdude is a great program (faster than anything else I've used) but you do need to tell it which partcular board or programmer you are using. You also need to tell it which AVR you are using, which port on your PC etc. As it is a command line app I suggest you use a makefil
2004-12-17 by Larry Barello
You have to make sure AvrDude knows about your PARTICULAR cable wiring. If you look in "avrdude.conf" the required information should be really obvious. Avrdude is very nice in that way. There are lots of parallel cable programmers out there and for some reason they all seem to u

Since I am using a parallel programmer, and I already used it with AEC ISP software to program AT89S8252, I am sure it works fine (it just a cable that connects MISO, MOSI, SCK, RST and GND to the parallel port). I checked continuity from the DB25 connector to the ATmega16 progra

The internal BOD work great. The only reason to use external one is to be able to route reset signals to other chips, or, to get an interrupt of impending doom so you can do something intelligent before the power crashes (I wish Atmel had THAT feature...) -----Original Message---

Bernd; IIRC, the RC servos take a 0.5ms to 1.5ms pulse input at about TTL levels. If you're really strapped for power, you could always power it down until the reading needs to change. The pointer could be something simple made from pastic, like a disk with the 'needle' drawn on
