digital ECM bench (proof of concept)
I've been tinkering around with building pieces of a digital ECM bench. Here's an ALDL plot of 4 ECM inputs being driven by a digital potentiometer attached to an AVR micro controller. Long way to go before it's done of course, but fun to see some progress! 
I still need to come up with something better for that CTS input....

Re: digital ECM bench (proof of concept)
looks like fun. the analog bench I have definitely has some noise on some of the outputs, I can see value in going digital!
