To connect the spirit to an s.port, is it a direct connection of signal and ground, or is a resistor required?
I use just signal and ground for all my quads from the flight controller to s.port on the xsr or xsr (pinless) and want to do the same for my helis.
I know you sell a cable, but I can solder just fine and would like to make my own.
[SOLVED] Frisky integration s.port
Hello,
to make it work you will need the FrSky integration cable in any way.
Since there are more than 6 SMD parts (including chips) inside, it is not easy to solder it at home.
There are bi-directional invertors for allowing the integration. So it is not just as a telemetry where it is enough to receive data.

Unfortunately it is not usual UART / COM communication. It is completely inverted logic which is unsupported by the most processors.
So it must be emulated by software bit by bit which is possible but is adding much more load to the processor. Quad copters very likely not support also integration in same manner as Spirit so communication is quite limited. Doing it by hardware is much more efficient.

What processor are you using? Most have serial inversion on the serial ports.
Bit banging serial comms is processor intensive and would detract from the core business of stabilising the heli.
If you are bit banging, then inverting the signal is totally possible in software!
Are you using a serial port or bit banging?

Don't worry, we are using the best possible way.
Hardware serial inversion is possible only on a few selected MCUs as I have said. Unfortunately the most have not this possibility.
We are using STM32F4.
You really can't help with this issue, all is already solved.

You can see RPM in the software if a RPM sensor is connected to the unit in the General - Throttle/Governor window.
But telemetry variables are not displayed there.
