Re: Inter-Display link protocol documented
Ok, I'll hijack the VPX data out then. Thanks Jeff.

Re: Inter-Display link protocol documented
The AHRS serial out, could that be shared? Actually let me be more specific. I'm looking for the IAS and altitude, is any of it calculated inside the HXR, or are all calculations done inside the AHRS? If the HXR massages the data before display, my best bet would be to hijack the GRT data out to the...

Re: Inter-display data
What is the best way going forwards with this? Should we sticky any packet breakdowns in another section, or just ask which ones we are looking for?
I'm looking for the IAS and baro/altitude (stuff sent to VPX), I have the GPS breakdown already to get the ground speed.

Re: Inter-display data
I have some info here on the serial data. FrameFlags, char stuffing, etc

I have not run across the angle-of-attack yet.

Bluetooth code
Is the bluetooth protocol going to be allowed for public to see? It's pretty smooth with not much data lag. I really think you have the 'edge' on the competitors having an android app link to the glass displays. Just need the app to 'expand'. Hopefully sometime I can show you guys what I am up to, w...

Re: App in Landscape mode
What is the vision for the app?
Landscape and portrait should be universal.

Re: Source Select
Ok that's what I was thinking.
I don't have any serial outputs left on the HXr for extra autopilot. I'll only be flying VFR for the next 3-4 years anyways. Hopefully by then, there is will a 'blackbox' that can expand the serial ports via Ethernet cable.

Source Select
What is the point of having the source select? I have HXr and Mini-AP.
Correct me if I'm wrong, having the autopilot connected just to the Mini-AP serial port, the HXr can control it through the Interlink? The only case would be if my mini or interlink went down, which I'd be landing anyways.

Re: Stratux ADS-B Reeceiver
It still requires modification. The zip file you guys have listed in your supplement, won't bootup on the latest raspberry pi 3.
I changed one line in the code to switch from USB to the GPIO pins. If using USB, you can't have GPS. But you can with GPIO pins.
On the bench testing, seems to work fine.

Re: Stratux ADS-B Reeceiver
I did mine a little different. I didn't like having a micro usb cable plugged into the side without it being secured to the PI. Plus having a USB-Serial cable seems to disable the USB GPS for now (with current code V1.0r1) The GPIO serial data & power go to a DB9 connector. The blue board in the...
