Nice...
This little hack was the difference between an LCD running with the Teensy 3.2 @ 48Mhz and 120Mhz.
I couldn't get pinModeFast() to work, so I copied the line above into core_pins.h above...

Ahhh...I was under the impression you were going to use the whole grinder. Either way, same difference. Measuring power either way.


Again, a boat type thing pulling a line hooked up to a fish...

Purely mechanical...a few...first two using a fish weighing scale
1) Lock the R/A grinder into some sort of fixture that allows it to rotate a bit around the plane of rotation of the grinding wheel...

That's what I'm talking about...a trigger that kicks both of them off on the same clock tick, and ya, low-level registers for sure. When I was reading/playing with my STM32F4 Discovery board, I saw...

Yep, that matches with what I'm reading so far, both here in the forums and in the datasheets. Awesome. I think I'm going to dig these ARMs.
Since the whole project is basically a curve tracer, I...

Synchronous!
That's the word I was looking for.
I got it now.
One input to ADC0, 2nd input to ADC1, set up the DMA, set up the triggers, BAM...good to go.
As long as the ADCs and pins are...

Do a search on YouTube for "w2aew audio limiter".
Might point you in a good direction if you're electronically inclined...otherwise, it'll just mash your brain.

Read thru them again... Can't seem to find a definitive answer as to whether or not the dual ADC reads are actually simultaneous (within the MCUS jitter limits) or just very closely read...

Yep, reading thru both of those...although not at the same time...I don't have dual thread-to-information converters :D ...
Maybe I'm not looking for the right phrase in the threads themselves.
I'm...

Background: Pet project of mine that I've been playing with off and on for years, basically boils down to a digital-ized curve tracer, a Huntron ProTrack type unit but smaller, cheaper, and I built...
