"Your work looks great. Any progress since the last post?"
"Did you cut the circuit trace to separate VIN from VUSB?"
"Rolf, IT WORKS!
The data was being passed. I finally saw how it was being reinitialized. Once I corrected that the data appeared in the Taranis as expected.
I did some playing around with sending data to the SPort when I couldn't get the live data…"

"I just now found the Mavlink RAW GPS code and saw that it deals in decimal degrees, not degrees and decimal minutes. Now it makes sense.
I understand your program only sends data on a 3D fix. I turn on he LED when I have a 3D fix, so I have some…"

"Rolf,
I was just looking at the information you provided about the conversion FrSky does to the incoming GPS Lat and Long data. It answered my questions about how it determined N-S and E-W. Now I'm wondering what the AP does to the raw GPS data. It…"

"Rolf, I'm having issues. For some reason none of data in the ap_ GPS variables (eg ap_groundspeed) make it from MavLink_FrSkySPort.ino to FrSkySPort.ino. They all end up zero. Got any ideas?
Not having real data from the GPS to work with, I took…"

"Disregard my last. I just connected 5V from a BEC to VIN and the USB Serial port appeared. Now I have to figure where the 5V from the SPort went.

"I did that. My SPort connection looks like the one you have pictured above. When the X8R is powered up the SPort provides 5.25V to VIN. The GPS is connected to Tx2, Rx2, 3.3v, and GND.
The USB serial connection just disappeared fom the menu. Should…"

"I cut the trace. Now the USB serial port is no longer an option. What do I need to do to be able to use the USB as a serial monitor again?"
"Rolf, I think I've managed to modify your code and Adafruit's code so that I have a GPS trying to send data to the SPort. Nothing appears in the Taranis yet, but that is to be expected for the first try.
I currently either have the Teensy connected…"

"In FrSkySPort.ino the integer ap_longitude and ap_latitude are divided by 100 and the result multiplied by 6 before sending to the SPort. I understand oring with 0x80000000 to set bit 31 high, but why the arithmetic? The photo of the Taranis shows…"
"I read that the S.port runs at 3.3V. I recently put a multimeter across the pos and neg leads an got 5.26V. Why the discrepancy?"
"I'm interested in connecting an EagleTree GPS to the Teensy3.1, and Sport. I'm also a noob to C++ coding. I've got 40 years in programming on mainframes in a dozen languages, so the learning curve isn't that steep. I was just hoping that Rolf might…"
"I look forward to the results of your in-flight testing. I too hope to be able to do autonomous soaring with Adrupilot. I will be following your work, and that of Jean-louis Naudin with interest.

Looks like I will end up getting a laptop for mission planner. As MP is all I need it for, I can't see investing a lot of money to run it. What is a reasonable minimum platform to run MP
"Jean-Louis are you still there?
I'm very anxious to be able to test your Thermopilot software on the APM 2.5 hardware."
