SparkFun Wiring ATmega1281 board running under Arduino

Many people (including myself until recently) do not realize that the Wiring project pre-dates Arduino. Apperently the Arduino took off while Wiring did not was because of the price point. The Wiring board was around $80.00.

Recently Sparkfun came out with a new Wiring board. The Wiring ATmega1281 DEV-09663 This board has

• ATmega1281 cpu with 128K bytes of flash
• 2 Hardware serial ports
• 8K Ram
• 4K EPPROM
• 54 I/O lines
• 8 Analog lines
• 6 PWM (Pulse Width Modulation) outputs

What's different

• It is NOT sheild comptaible
• It uses STK500v2 instead of STK500v1 for uploading
  (This is OK because Arduino supports V2 as well as V1)
• It can be used on a bread board
• The normal Arduino environment does not support it.

I have made a version of the Arduino support code that fully supports the Wiring 1281. It has been tested under Arduino V0018. The only part that is not fully tested is the analog and timers.

Updates:

• July 5, 2010 I have updated the PWM code and test PWM on all the ports that support PWM.
• June 22, 2010. I have uploaded a new version that now supports the original Wiring Atmega128. THIS IS NOT TESTED AT ALL If you have one of these older boards and try it, PLEASE let me know if it works as I do not have one of them.

Click here to download the code to support the Wiring 1281 under Arduino

Download the file, unzip it and place it in your "hardware" folder.

On the mac this is Applications -> Arduino.app -> Contents -> Resources -> Java -> hardware

If you use this file, please drop me a not and let me know. Also if you have any problems or questins about it.

This first release (June 2010) does not include a bootloader to burn. I am working on it but you DO NOT NEED TO BURN A BOOTLOADER. Arduino works perfectly with the boodloader already installed in the board.
