Hi Bruce
Are you still building this project? we havent had a update from you for a while.
Thanks

I have been reading this forum for a while, and it was RC Model Reviews that put me onto the FRSky telemetry system. I have been playing with telemetry for a while (vario, altitude, motor current) but the FRSky unit does away with the need for the transmitter on board and also gives me a 2.4G system. On looking at the FRSky protocol, monitoring the Tx output, and some PIC coding, I have not managed to reliably isolate any particular frame because the hex start/end codes (7E, Fn,x,x,x,7E) appear in the frame as well as the start/end. From the photos of the LCD at the intro it looks as though Bruce has managed this. How? What are the criteria for the frames? For info, I am using the MPX4115 pressure sensor and a 20 bit a-D for altitude, but this device uses a 5V supply, unfortunately. The GPS chip is the LR9101, but at 1 Hz frame.
Keep it up, enjoying the discussion, and awaiting the end result.

"I have altitude, fuel level and current;/capacity sensors for this displays but didnt released yet. I will write the code for sensors and different display alternatives as "voltage+fuel level" displays for fuel level sensors or a vario+voltage display(vith speaker) for gliders.
I need time for all of designs "
