Mac arduino 022 hardware recognition

From the readme:

Step 2 (Mac only)
Clone the repository at

-https://github.com/jmgiacalone/sanguino1284p

and copy the included Sanguino directory to the hardware directory of your Arduino install. On Mac OS X, that would be ~/Documents/Arduino/hardware.

Step 3 (Mac Only)
Close the Arduino IDE and then copy the file avrdude.conf from the sanguino1284p clone to your ~/Documents/Arduino/hardware/tools/avr/etc.

Start the Arduino IDE and you should now see 'Sanguino W/ ATmega644P' AND 'Sanguino W/ ATmega1284P' options in the Tools->Board menu.

Have you done this?

I think this depends on how you got Arduino 22.  I downloaded the prebuilt binaries which were packaged in a .app folder.  You just copy it to your Applications directory.

When I had to add the Sanguino to hardware, you find the Arduino.app in the applications directory using finder.  Then "right click" or use CRTL-left click if you don't have a right click capable mouse.  When the menu appears, you will see "Show Package Contents"; Click it.

Drill down through "Contents -> Resources -> Java -> Hardware" and place your sanguino directory there.
The avrdude.conf goes into  "Contents -> Resources -> Java -> Hardware -> tools -> avr -> etc".

If you built Arduino 22 yourself, this might not work.  I haven't done that, so I don't know.

That's what worked for me.

Thank you everyone for helping me out. I have just one more question regarding this. Do I select 1284 8mhz or 1284 16mhz in the hardware drop down menu? Thanks

Avrdude: AVR part "atmega1284p" not found. I did everything on the install wiki step by step, Including putting jicama line's Sanguinololu folder in arduino/hardware, both Mac and now Pc. Still getting this message- what am I not doing?

Good to hear. I put that up a while ago but most people don't really read instructions. You're probably the first to use it.

Happy printing.
