Re: Search for Replacement 9x Potentiometers!

In my first Taranis they have a op-amp circuit to shift the levels of a standard range pot. The Taranis uses 3.3V, 9x uses 5V. New version do not have this circuit because they have the custom ~60 degree rotation resistive range pots (they are 5K).

Re: Taranis LCD, no or very low contrast

Good point, I looked closer at the voltage levels. Looking at the Ti TPS5401 (U3) buck regulator, R76=29.4K R77=10.0K Vfb=0.8V Vout calc = 3.152V I measured on my good Taranis: R76=29.33K R77=9.97K Vfb=0.8 Vout calc = 3.146V. I measured my good and bad Taranis LCD voltage = 3.124V and 3.129V. ~23mV ...

Re: Taranis LCD, no or very low contrast

More info, not solved yet. I scoped and pinned out the LCD connector. I was hoping to find an analog signal to adjust the LCD contrast (I have seen this before on a digital goto telescope (LX200GPS-14"). The LCD pin number #3 is a strange voltage, I adjusted the contrast while watching this pin, and...

I have a spare Taranis that developed a LCD with no or very low contrast, the back LED lights are fine. The rest of the Tx works perfectly. By lowering the brightness and increasing contrast to max, I can just read the lcd at the right angle. I bought a replacement LCD from Aloft and same. Not knowi...

Re: Convert PWM to Voltage for RSSI

I am yet to get an FrSky RX but I believe that the RSSI signal is a 1000 - 2000 microsecond pulse, once per frame. This means that you should get a 2 millisecond (max) pulse with a large (18 - 20 millisecond) gap. This would mean that the "charge pump" capacitor / resistor solution will not work we...

Re: Convert PWM to Voltage for RSSI

Of course your going to have to use an RC filter from the RSSI output to the OSD input, I suggest a 1K and 10uF. And then your probably going to only get ~60% of full scale on the OSD (RSSI is 3.3v max, your OSD is probably 5v), what I did was add a trimmer pot after the RC filter to adjust the 100%...

Re: openTx-r2215

With openTx, you have to choose the things you want in the preferences screen of C9x. If you didn't tick potScroll and thtrace you won't have them. On the stock board not all options fit at the same time. With er9x, I'm trying to avoid having compile time options like these. Mike. Excellent! Thanks!
