This just means one I2C bus with all of the I2C traffic control from Codesys and my custom driver profile (actually 2).
I had to mount a riser to the IMU so that it cleared the Pi ribbon, and the DAC adapter did indeed turn out to be horrendous. But it works, which for a prototype board is good. I didn't even have to cut traces, which to me is a win.
There are are a lot of milestones I met with this board.
- Board layout software (Eagle 6.6.0) worked well, and generated good Gerber files.
- OSHPark did a phenomenal job on making the board. I can't say enough good things about them.
- The design worked. Yes, I forgot some missing jumpers, but the design is now proven to work.
- Through hole is still king for me right now for ease. That single SSOP16 to DIP adapter for the DAC has proven the most work. I know I should have checked, but I would ASS U ME, that the nice, wonderful, super cheap adapter you bought, isn't screwed up right? **cough Sparkfun**. I will avoid SMT until I get my reflow oven built, and get setup for it.
- My several parts I made were perfect, and I am very happy with the overall look and layout of the board.
- I last designed a board using Ultiboard in 2002. Ultiboard and Ultirouter cost $10000, and getting a board made cost between $1000 tooling and setup and $50-$100 each per board. Now I use Eagle at $200, and it cost me $95 for 3 boards.
