eZ Navi Delete Project

Would it be possible to turn off the open driver's door beep under ACC mode with this project?
My previous 350Z had a spade lug in the steering column that you could pull to break the circuit. That was simple, CANBUS is a bit different.

I know exactly what you mean... as someone who has spent hours sitting in the car testing this and other projects, I can confirm it is awful. I have never looked into how the signal propagates in the system. It may not be CAN related. The problem is that if it is, there is some device pushing CAN messages that define the state of the chime (on or off). If my device also tries to send that same message and it is different that the other device in the car sending that message, the receiving device will get confused and may throw a code. Think of it like this, two people talking to a third person in a room telling them if he should ask a girl out. One is saying "YES" over and over while the other one is saying "NO" over and over. What's the guy to do!?

For those interested...

Below is the first spin of the updated version using the more powerful ARM based microcontroller. Sorry, I dont have 3D models of all the parts

... Time to order another kit of parts!

Turn car to full on position. Shut door. Lock and unlock with key fob. Open door no beeps.

I really, really can't wait for this to be 100%....

Board fab and parts kit ordered. Should have first assemblies in a few weeks.
I have spent some more time with the code and focused on Bluetooth related items. The new version assembly should allow me to test the full intended functionality of this design. The app interface is also making progress, so I am told. Really looking forward to testing that out!
