What resolution (how many bits do you need)? How many channels?
Thanks for the response. Your question implies third party hardware, is that correct? I have assumed due to the lack of response to this thread that there is no method built into MACHH4, so that leaves third party stuff. Considering that MACH4 really needs a third party motion controller, it would nort be surprising if they left it to that device to provide analog input.
To your question; 12 bit would be nice and for now I only need one channel. The application is to input a 0-10v analog signal from an industrial A/C servo drive to MACH4 in order to get an on screen display of the motor load.
Options that I have now are the Arduino DUE processor in the 4th axis motor controller and a Pokeys board. I have the USB version, but now there is also an Ethernet version. The DUE has 12 analog inputs, each of which has 12 bit res. I don't recall offhand the PoKeys spec, but I know it has Analog I/O.
I also have an ESS, but I'm not sure if it has analog input or not.
