Hi all, i asked myself, if it could be possible to code a metronome program for the FV-1. As far as i know the classic mechanical metronomes can do 40 up to about 200 beats per minute, which means periods of 1.5s down to 300ms. I am not very familiar programming the ASM for the FV-1. Is there enough...

The I2C isn't a real I2C with OC drivers, but the separated data in/out ...
