Hi,
I’m working on a small cnc machine with a 124x600 display. I anticipate most of
the use to be selecting a new file and adjusting work offsets.
I’d be happy with the gmoccapy UI but it simply doesn’t fit on the screen. My
plan for now is to edit it and remove some of the manual control
Arduino? Too slow to coune pulses if they happen every 0.0001 inch unless
the table moves slow.
Look at the new Raspberry Pi "Pico". First off it only costs $4.Next
if you looks, it can be programmed in Python and here I the Key: In
addition to the two CPU cores it has 8 "PIO" processors
day 2...

I think that I would
Remember - the excitation signal is 250hz I want to measure wave form
to wave form within that at a minimum of 1000 counts. Not much power

I recently acquired a Palmgren 800 rotary table for a faction of this cost.
I would like to modify it to mount horizontally or vertically on a small mill.
I'm open to suggestion before I
The only issue on an Uno would be interrupt latency. If you disable all
other interrupts, latency should be easily low enough. The only real
advantage of going to ARM is interrupt priority. You could assign the
sampling interrupt to maximum priority without having to disable other
interrupts.
I would suggest starting with a more capable microcontroller. I like the $15
Adafruit ItsyBitsy M4 modules, which are programmable with the Arduino IDE, but
have a 120MHz clock, 32 bit timers, floating point hardware, and two 1Mhz 12bit
adc's. Their processor is an ATSAMD51 (Cortex M4). The
My plan is to use the 16 bit timer on the arduino to trigger on the input
square wave rising edge and then count until it see's the return wave
form rising edge. (the return waveform will get converted to a square
wave) Atleast that is the plan...
SO - I guess it comes down to how accurate the

You might be able to do a lot better
