Topic: How to burn a Arduino Bootloader (Read 3296 times) previous topic - next topic


I used the method described in the link Osgeld mentions. Minimal parts required (1 Duemilanove, breadboard, wires and a ?0.40 resonator). Took me only like 15 minutes to bootload 10 Atmega328's.

Cheapest and easiest method, you probably only need to order the resonator or the crystal&caps.

Way better then buying a $30 programmer that I would probably barely use.


I used the parallel port method a month ago to burn 6 IC's.  Simply found an old printer cable, cut the end off, spliced in a connector and burned one after another.  Hardest part was finding the right setting for the parallel port in the Dell BIOS.

I have tried many homebrew methods..

parallel cable = no go
serial using another MAX chip (I believe) and some caps.. = no go

using an Arduino.. and a few wires was simple..and worked every time.

I actually ordered the BOM on instructables for a breaboard Arduino..

cost total about $7 bucks.. put all on bread board..

used Arduino to flash bootloader..

and since its on my breadboard.. I used a $3.00 data cable and the arduino IDE to upload sketches directly to the breadboard Arduino..

cheap and portable. =)
