Title: Arduino controlled Real HSI

This Real 737 HSI is controlled by a Teensy 3.1 using Arduino code. All but the compass card as couldn't figure out the 'home' stepper programming in Arduino. :(

Hey Rob.

I read somewhere someone was doing that. They used a photocell through a notch on the card. The card on power up rotates to the known position where the photocell catches it and resets everything. If I am not mistaken every time the card rolls past 000 it resets the position.

Just a thought.

Impressive.

Care to share your Arduino code?

Rob, nice work! Did you install stepper motors or are you communicating via the ARINC pins?

Thanks Robert,
I am using one stepper turning a remote mounted synchro to drive the Azimuth card. The Course and Heading bug are driven from the same signal fed to the AP panel which then sends it out to the HSI via internal synchros Using most of the original internals so far. All my stuff is to old for the ARINC 429 data. The digital DME readouts use I believe ARINC 561 but I will use an Arduino for that.
