CFF3000 GPIO Interface
CFF3000 GPIO interface ======================
This repository contains information how to interface a Abus CFF3000 remote control with a Raspberry Pi or similar development board using GPIOs. First of all one needs to disassemble the remote control. Be careful when removing the rubber part from the PCB to avoid tearing off the antenna.
Next step: Soldering a couple of wires. I tried to tap the signals at locations, that are as simple to solder as possible. Unfortunately tapping the LEDs is a bit tricky. Note, that the CFF3000 design is "interesting" and does not use a common ground/vcc for…
