HELLO,
The project over a long time trying CTCSS tone decoder. I made a filter that integrates with the TL082 and the tone frequency of 88.5 Hz as in the diagram below I entered 16f628A processor. My goal is to tone comes from the processor to receive any output port. In this way, to ensure control of any device of this valuable piece of software, I would wait for the help of friends.
