CIP peripherals

[Giuseppe MPO]

I hope it's not OT.
I had never used CIPs.
It took a little time to understand how it works but once I learn they are really interesting.
An AC dimmer that works virtually without a program line.
Maybe it won't be the best of optimization, surely it could have been done better,
I used ZCD, 2 Timers and 2 CLCs.

Thanks MPO for sharing your code it could be of help for others.
To date I have never experimented on these Configurable Logic Cells.
In the future I hope to do some tests on them
