I’d like to use the arduino, but I think it a bit over priced. I’d like to use the software with a regular AVR dongle by using AVRdude to burn the bootloader and then the arduino-software made .HEX file?
This has been done before, yes, but all the stuff i’ve seen didn’t have any documentation as to how. I’m going to be using a AVR parallel dongle and if someone could point me to the right direction of if someone could tell me how, I be appreciative.
(Note: Sorry if this already has been posted, or if this post is in the wrong place. Thanks alot in advance.)
thebluecommander: A cost effective solution would be to purchase the AVR ISP and plan on programming the chips directly without utilizing the arduino environment at all. It’s a steeper learning curve, but once you buy the AVR ISP, all you have after that is the cost of individual components. In it simplest form, all you need is the AVR chip itself and a programming header. No crystal is required if you aren’t doing anything timing critical.
thatoneguy: I would look at the schematic and copy the parts that you think you’ll need. Crystal, max232+, and decoupling caps for the processor will be needed at a minimum if you are programming via the serial port. Where are you getting power from? Will you need to regulate that power source? Answer those questions and add on any peripherals you’ll be using and I think you’ll be all set.
Only other option would be to build your own. Just power a atmega168 up and wire the serial directly to your pc. Burn the bootloader and set the fuse bits on the avr, but at that point you’re probably going to spend the same amount of money. Info on that here:
