Hi all,
I'm trying to tap the un-encoded PPM signal from an RC receiver for a flight control project with arduino. I'm going off this guide: RCArduino: How To Read RC Receiver PPM Stream but with the receiver I'm using, I'm not sure which chip acts as the "shift register", and thus have had to sort of guess my way through it based on looking at the datasheets for the chips (some of which weren't available). It's a turnigy 9x receiver.
The closest thing I could find that seemed to correspond to the "clock A" pin for the shift register in the example above was the SCL pin on the FT24C02A chip (pictured below):
Would this be the correct pin to solder to, or is there a different chip / terminal that needs to be tapped, and if so, what is the method for identifying it?
