Using an Arduino UNO board (and later for a UNO R4 WiFi), I am trying to write a sketch to detect state changes on an RC receiver connected to the Arduino. Where can I find documentation/references to help me write the interrupt routine for my Arduino board to detect state changes on the RC's receiv…

Thank you. I am looking for reference(s) specific to a receiver connected/wired to Arduino pins, with the receiver receiving radio wave signals from an RC transmitter.

Post #2 is your starting point.

I assume you mean decoding four PWM signals from your receiver. Do you want to do that or play with interrupts? What receiver make and model are you using? Does it have a serial output or PPM? Either might be easier than what you seem to be going for. Do you need to use that receiver? a7

I doubt a little that you need interrupts to detect state changes. You can have a look at the example Digital → StateChangeDetection. The trick is to constantly read the input and store it in a variable that you can compare with a previous reading. The below domonstrates uint8_t btn1LastState; ui…

I can recommend to have a look at the DigistumpArduino library collection. If you install that you will get a lot of RC related features. One of them is the interrupt driven SoftRcPulseIn library that is capable of scanning multiple RC channels in parallel without being blocking. It will work righ…

The only receiver I have is Flysky iA10B and the transmitter is the i6X that came with it. Data port: PWM / PPM / i.bus / s.bus. PWM channels: 10 (I only use 4 for now). Wireless protocol: AFHDS 2A. Thought of a sketch with: a function to configure the pins that trigger an interrupt an interrupt …

I get "An error occurred during a connection to digistump.com ." when I try to access the links in README of DigistumpArduino
