21.01.2022 How to Write your own Flight Controller Software Part 4. In Part 3 of our series on writing your own flight controller software, we looked at PID control and what that consists of. When writing complex software, it is usually easier to break it down into smaller parts which you can test independantly. Our path to functioning flight control firmware on an Arduino looks like this: 1. Pilot input (i.e. decoding SBUS); 2. Gyroscope output; 3. PID control loops; and... 4. Motor mixing and motor output. Our next challenge is item 3, feeding the error signal e(t) for roll and pitch into our PID loop and then outputting a corresponding PWM control signal to drive our four motors. https://reefwing.medium.com/how-to-write-your-own-flight-co

15.01.2022 Reading RSSI from a FrySKY X8R Transmitter with an Arduino - all you need to know! RSSI (Received Signal Strength Indication) is a measure of the signal strength between the Radio Control transmitter and the receiver. It is important when you are flying a drone and are about to go out of signal range! https://reefwing.medium.com/reading-rssi-from-a-frysky-x8r-

13.01.2022 Part 3 in our series on how to write your own flight control software. This article explains how we generate the error input to our PID controller. We have to compare data from the radio control inputs with feedback from the IMU (Inertial Measurement Unit). #drone #Arduino #Nexgen https://reefwing.medium.com/how-to-write-your-own-flight-co
