Help using Itsy for a module controller.

by Yacob454 on Tue Jan 30, 2018 1:13 pm

Hey how's it going? I'm interested in the Itsy, the Rasberry Pi Zero (or any other) to control a heated seat module in a truck (12 volt system). My question is can I program The Itsy to control power outputs for network communications? I have a lot of reference material attached to help. The module is a Ford heated/cooled seat control module. The part number for it is BU5Z-14C724-A. It has two MS CAN signal wires, one positive and one negative. It has a resting state of 2.5v on both wires and increases/decreases by 1.0v on a given wire to signal an activation of the seat module. I have added a few pictures for reference and can email much more. Thank you for your help.

The Itsy Bitsy doesn't support CAN directly, and we don't have any CAN peripherals, but peripherals do exist and a microcontroller will be able to talk to them.

The Itsy Bitsy won't be an all-in-one solution though.

Awesome answer. What type of peripheral device would I require to operate CAN?

It looks like these are some of the most common CAN interface chips:

From what I can see in a quick scan of the datasheets, the CAN bus uses differential signals (one goes high when the other goes low and vise-versa), and the transciever converts between that and the regular high/low signals a microcontroller would use. You'll still need to find code to generate the signals that tell the connected device what to do.

Awesome thank you for your help. This seems like a project way beyond my abilities. Are there people or companies out there that specialize in doing custom things such as this?

There are design houses, but they'll probably be pricey for a single device.

Check to see if there's a hackerspace near you, or a community college with an electronics program. Those are good places to find people willing to take on a small paid project.
