Doc,
That looks comprehensive up until recent discussions where Grant mentioned 8
Analog Ins and 8 Analog Outs. It's great if the board can support that
many. Of course builders can populate those portions with circuits, jacks
and knobs, or not, depending on the size and configuration of their module.
I would like just one more digital input to be used as a "Menu" pushbutton.
With eight inputs and outputs, this would be very handy to toggle through
reminder screens for the programmed inputs and outputs. First screen shows
mnemonics for Inputs 1-4, press menu to show mnemonics for Inputs 5-8, press
again for Outputs 1-4 and again for Outputs 5-8.
If we can't add digital inputs, then I believe it might be possible to just
use the "Run" pushbutton. First press starts the program and shows first
set of inputs, then each press toggles to the next set of mnemonics. This
seems possible, but not having a PSIM I haven't delved into the programming
details of the ATOM PRO yet.
I'll tell you one thing, if this module supports eight Ins and Outs then the
LCD screen suddenly becomes REALLY useful for remembering the IO mapping of
the program.
