V0.2 Hardware and firmware

Finally got around to fixing the board.. Again, this isn't tested and won't run with the posted firmware (Added software mode control to the CAN transceiver, will need to add control of that to the sketch.)

Board:
CAN_Shield_V0.2.zip

Latest mostly working firmware:
gmPod-100510a.zip

There are still a few small bugs in the firmware I am working on but this is 95% working and working well.

Proof!

Got the display glitches working. Needed a 30ms delay between packets in multi packet DIC messages.

Here is gmPOD hardware that I have working:



And some videos.. Taken with my phone. So the quality is nasty bad..

It really works!

gmPOD success!

Folks,

With the pin 8 ground wire mod in place, the PCB as posted works great! The Alpha software was up and running today!

I still owe you a V0.2 board. And a few pictures!

Hardware is done. Now onto the software!

Found a bug in the gmPOD sheild..

The gerbers I posted have a bug. Pin 8 on the AU5790 is NOT grounded. Will revise tonight. Oh well, I will have a mod wire!

Boards have shipped

Been a while. And no.. I have not forgotten this project.

My PCBs have shipped, and I have the 16 pin connector to mate to the connector behind the glove box. So, this weekend it will be game on again!

Will keep you all posted.

Alpha Boards and Schematics

Got two alpha level boards ready for batchpcb. Attached are the eagle files, gerbers, and schematics.

This is the arduino sheild. Single wire, MCP2515 based. Again, I have no idea if the boards are good yet, just have to wait for the fab shop to get them back to me. This one is iPod centric and has 3.3V RS232 out and 12V for charging the ipod. I will do more of a pure single wire CAN board later if this works.

*** LINK REMOVED *** - FOUND A BUG IN V0.1

This is the ELM327 scanner I was using to hack all the CAN messages. Meant to hook up to a FTDI TTL to RS232 converter on the 6 pin header.

These are alpha boards and may (will probably) have bugs. USE the boards at your own risk or let me debug them first ;)

Success!

Finally have the hardware and software together... And I can report a successful test of the ipod adapter!

Other then small bug fixes and a multi CAN packet display driver, everything is working as expected. I hope to finish the hardware this week and get the Tyco connectors so I can wire the thing into the factory nav connector behind the glove box.

I will also post video soon. And Source. And schematics. (When I get time!)

Any interest in getting a single wire CAN arduino shield fabbed up? I will probably get one done with batch PC. Would be willing to get a couple more for anybody interested.
