Skylark Tiny OSD RSSI with the spektrum receiver.

Hi Skylark,

I have been doing some testing on the RSSI with the spektrum receiver. According to your instructions I have calibrated the RSSI with the aux channel (flaps on the DX6i) going from one side to the other and now I'm able to have on screen 99% of RSSI when the flaps channel is on and 0% when it's off (sounds obvious) so I'm pretty sure that the signal is recognized by the OSD, BUT it has no change at all. If the channel is on, it shows 99% all the time no matter the distance. Here's a video of the switch being toggled. Is there's something I can do ?
Thanks,

@Skylark
This can be easily explained. 
You connect a aux channel with RSSI pin, the OSD get aux signal, so OSD screen show the aux signal value, but it isn't realy RSSI. Every RC receiver channels will keep the fixed signal output(unless you push its stick), they won't change along with the distance.

As we have explained, the testing of aux channel is only to prove that OSD can deal with PWM signal, just it is used to demonstrate the feature.

If you want to get correct RSSI, please connect RSSI pin of RC receiver with OSD(RSSI Pin), then calibrate and test them.
