Re: Inter-Display link protocol documented

So I'm using a Teensy 3.6 to capture the interlink data. I was having troubles if I started the HXr before the teensy, the teensy wouldn't process the serial data. The serial data was there at the pin, just nothing was happening. If I unplugged the serial cable a few times, it would catch and start ...

Audio & discrete outputs

On the HXr, Audio Out Hi is pin B24. Is there an Audio Out Lo?
Hooking up to PS-Eng PAC15EX

And I'm guessing the 8 discrete outputs are A6 - A13?

Starter contact - bug?

The VPX starter contact message, it seems doesn't show up on the Eng/Map screen. Unless that's by design. But you'd think people would start the engine on the Eng screen.

Re: Inter-Display link protocol documented

ok Gotcha, I'll stick with ground speed from GPS.
I'm finishing up sending GPS data (0x09 0x00) to the Megasquirt ECU, is there anything in the GPS packets 0x09 0x03 and 0x09 0x04 worth while? GPS altitude?

Re: Inter-Display link protocol documented

The addition of 'Air/Ground Transition speed', is that flag being passed on inter-display? I'm basically trying to find out when we are flying vs on the ground. Right now I'm using the GPS ground speed (better then nothing).

Re: Backup Battery Voltage

Using VPX for amps, not an actual dmm.
Just on a screen, not full load.

HXR + AHRS
Dim 1.1A - 1.0A
Full 2.1A - 2.0A

Re: Sport EX USB output current; GPS required?

1. I think uAvionix's pingEFB (60mA) replaces the two SDR receivers (300mA each). So it appears that the total draw (Stratux, pingEFB, GPS, fan) is well under an amp. Can the Sport's USB connection supply that much? 2. Can the Sport use its own GPS data, or does the Stratux have to have its own GPS...

Re: Stratux ADS-B Reeceiver

I am confused about the answer to the question about using USB. Why convert USB to Serial and back to USB? Won't a regular USB cable work directly? The raspberry pi USB is a host mode controller. You plug devices (device mode) into it, keyboard, mice, gps, etc. The GRT is also a host mode controlle...

Re: Inter-Display link protocol documented

Ok, I'll hijack the VPX data out then. Thanks Jeff.
