I wanted to make a SID monitor to display the 3 Channels of a C64 SID chip. This requires 3 SID chips, so this is a work-in-progress.

I bought several display I2C 128*32 in China, for cheap .. to have some stock .. So much for having stock.

But monitoring works! I’ve made 3 setups using a Wemos D1

Monitoring, scrolling monitoring and FFT analysis.

When mode selector using a button works, I’ll post the code.
