Decoding FrSKY telemetry data with an Arduino – Part two
In part one, we looked at the standard FrSky ‘D series’ data packets that provide voltage and RSSI information. In this part two post we’ll consider the data format used by standard FrSky telemetry add-ons and how to decode the data from those without using a Taranis transmitter or a commercial display unit. In part…

Decoding FrSKY telemetry data with an Arduino
I used a FrSKY D4R-II receiver and a DHT DIY Tx module with an Arduino Pro Mini for the purpose of this post. These FrSKY products use the older “D mode” telemetry and the DHT module is now discontinued, but I’ll be updating this post to deal with the newer S.Port Telemetry soon. There…

Decoding 6 servo channel inputs with an Arduino UNO
Standard radio control receivers drive their connected servos by outputting a train of pulses. The pulses usually repeat at a 50 Hz rate but the pulse width is the important thing – the standard is a 1.5 ms pulse width for a servo at its center position varying from about 1.0 ms up to 2.0…
