Electronics for my Mustang?!?
Clearly there are no electronics on the mustang. Except the PCM for the new Coyote engine.
But given my background in electronics engineering (and not mechanical), I decided to start tinkering with some things I can do to have a nice setup I can expand, and have it readily available for other people to install if there is interest.
The single board is based on Cypress’s PSoC family of controllers. I chose them given their flexibility, and the fact I can get some crazy implementations done, even future-proofing the design. So I can add internally what I need. If this is foreign language to you, skip this part…
The idea is to have a GPS, an accelerometer (3-axis), and an RFID reader. The controller has a CAN peripheral to implement the OBD-II communication with the Coyote to get the engine data. Of course there are off-the-shelf setups to help with this. But none to allow me to customize to what I need.
The RFID will allow me to start the car with a card, a RFID keychain, even my phone. All I need is to register the cards which are allowed (up to 3), and use them just like a key.
The GPS is really to get location and speed (as a redundant source), and whatever else I want from the multiple data streams it brings in.
The accelerometer is really to get acceleration (duh!) for really handling and data collection.
I reserved a link to a bluetooth module in case someone is interested in taking the data from the module wirelessly and using an off-the-shelf tablet to create a custom GUI. I am not an expert at the GUI deal, so I will keep this until the end and find someone to implement it for me. Once I have all the data in the controller, I will post it up and see if there are any takers.
Future proofing: video feed (front, back and side), Capacitive sensing user interface (no more mechanical switches) so I can make a custom and light-weight dashboard, and other ideas I might have before I implement the whole thing. any ideas you have would be welcome. This is a long term project, so no deadline. But will keep everyone posted on the progress.
This is what I have so far. The setup is working and the mustang logo shows up on the LCD. It’s alive…
On the right side, you can get a glimpse of a RaspberryPi board. I started dabbling with this as a host PC for the car. But that would be phase 2 of the project, part of the GUI.
