Re: FreeEMS hardware feature wishlist (your suggestions here!)

Can I have VSS too? Please please!? I would actually like to completely replace my dash with an LCD gauge cluster, so it'd be helpful. Now I'm guessing that the MS freq/voltage rig is less accurate, but it saves cycles? You can poll the adc whenever you want rather than having the VSS use up a coun...

Re: Trigger decoding, a few thoughts...

I like this idea. Actually I had a related idea as far as trigger decoding... What if the trigger inputs were sampled in pure form (with voltage clamping of course) by an ADC, and through digital filtering and comparison to a stored sample of an entire engine cycle, the precise position, speed, and ...
