Programming AVRs

You might want to know how to run avrdude from eclipse under linux.

Atmel has released a 4K version of the well-known Attiny2313, called the Attiny4313. It is fully (pin) compatible, with the only difference that it has double memory. The Attiny4313 is not yet recognized by Avrdude, so we have modified the Avrdude config file to be able to program it. This link contains the Attiny4313 section that should be added to your config.

Our set up

Nowadays, we prefer to do our stuff in SMT because it avoids the bore of drilling holes. And you can make use of cheap SMT resistor and capacitor assortments so you'll always have the right values available. Working in SMT requires making PCBs. We use the toner transfer method. One tip: the ironing sticks much better if the paper is wet. And one other tip: etching in CupricChloride works very well and you never run out of etchant!

ToDo List

Here are some projects on our to do list:

  • CC2500 Wireless System, on hold while we're working on the
  • Nordic NRF24 wireless system
  • AVR DAC Audio playback
  • Midi Chord generator
  • Solarpower Chicken Lighting System
  • PIC-based MidiFilePlayer
  • Drumcomputer
  • DCC Train control system
  • simple GPS logger based on rs232 receiver
  • sunrise alarm clock

Items that were on this list, but are finished now (without write-up)

  • 100Mhz SX based Frequency Counter (done)
  • AVR Bootloader System (done)
