Re: [gpsd-users] using gpsd on Cubieboard with Garmin 16x-HVS and app written in Qt

[George S.]

Email me off-list and I'll send you a schematic of a working interface between a Raspberry Pi, and a Garmin 16x-HVS. It should work with the Orange Pi, you'd just need to adjust what pins you connect to.

The major issue is that the Pi runs 3.3v while the Garmin 16x runs true RS-232. A Max3232 chip can be used to do the conversion. SparkFun sells a break-out board BOB-11189 that I used to handle level conversion.

Just for good measure, I interfaced an LED 7 segment display to one I built. You can see it here:

The clock display is run by the little board on the right. A C program using the WiringPi library runs forked in the background and continuously updates the time display. It's pretty cool.

Unless you have a real desire for the Garmin unit, you might consider using the SparkFun Venus breakout board. I've used them with the Raspberry pi without issue. They sell a 5M external antenna.

Hi all,

I need some answer/guidance if anyone is familiar with similar setup: 
Microcomputer Cubieboard2 or Orange Pi plus
Garmin 16xHVS or some new model
at least 5m long cable between computer and the receiver. 
Qt app using gpsd as a position source.

Will this work reliably if I connect PORT1 of the Garmin dev to 3.3 V UART on 
microcomputer with cable length at least 5m ?
Or should I use usb to rs232 adapter ?
Would you recommend some newer/different model of the GPS dev to work with?
This setup is for tracking a bus in an urban environment.

Best Regards
Marek
