Arduino/ATmega/JeeNode port/pin diagram

After seeing a few questions and comments about putting non JeeLabs bits onto JeeNodes, and having done it myself a few times, I thought one of these might be useful...

Basically it's a pin diagram of an ATmega. All the pins are labelled with all their known names. The Arduino names, the JeeNode names, and anything else I could think of whilst I was doing it!

Thanks to Stef007 for his fantastic link http://tinkerlog.com/2009/06/18/microcontroller-cheat-sheet/

I combined this with info from JC's Jeenode V4 PDF...

The ports are labelled JP followed by the port number, then A for analogue or D for digital. The interrupt pin is shared across all the ports so labelled JPint. The pins to the ISP are labelled, which are common to all the ATmega based board. The JeeNode then added two extra pins, 8 and 9 which give access to the Arduino digital 8 and 9.

Hope this is helpful.

Nice work tankslappa! Something to print and put on the wall;-)

A small addition usefull for people that want to use the hardware I2C support of the chip:

Add (SCL) in between PC5 and "Analog 5 PSI5"

Add (SDA) in between PC4 and "Analog 4 PSI4"

Personally I would also indicate the SEL0 and SEL1 of the SPI port. They are not known by the atmega as being "SPI device selectors" but JC provided them to add support for additional SPI enabled devices on the SPI port (I presume). BTW you mislabeled those in the drawing: ISP8 should be ISP7 and ISP9 should be ISP8.

Thanks for the input, I've incorporated your suggestions and corrected the mistake! Thanks for the heads up.

Hopefully the link will remain the same, if not I'll code back and update here.

update

Guess what... URL changed... I'm going to put it up on my server instead... And PDF it too. http://www.ishootpictures.co.uk/atmega-pins.gif

Great:-)

Ok if someone could just integrate this into a JeeNode cheatsheet like this one below for Arduino.... Just kidding, that would be a lot more work and getting the authors permission and hopefully the source document. But still the cheatsheet is usefull also for JeeNode developers so I thought I put the link here.

Well he admits to pinching the images from fritzing under CC, which I don't think permits him to copyright his work in a restrictive way... So in theory as long as I credit him too, I can pinch his... Looks like he's got part of the microcontroller cheat sheet in there already too.

After burning the RFM in a jeenode (I plugged a pin in a wrong plug) I created this for my latest sketch. (The Jeenode layout in the top of the sketch)

@jeroen, nice work, I was thinking about doing a similar thing, but I got sidetracked!

I'll try to update the diagram I made for the bare ATmega and add your Jeenode layout to it too.

Good idea to have this info close to the code!
