That's really interesting - it might be perfect for what I'm trying to do here. But it seems pretty advanced compared to my present level of comfort with electronics.
To do phase current measurement on these it'll take something better than my 1980's era o-scope I expect. What's a good budget scope and current probe setup?
What scope do you have, model ?
These excellent scopes these days -
Hantek DSO2SC10 or DSO2D10 (it gets shipped with 1 probe, you have to buy another to use both channels).
Rigol DS1102Z
Low cost current probe just use a sampling R in low side or in high side and use scope
in differential mode. Or DIY - Google "DIY Current Probe", lots of solutions.

Think of PSOC as a pile of components and a breadboard rolled up into a chip.
You drag and drop the components (a component in PSOC lingo is an onchip resource)
into design area, double click it, and config it, like for a counter its # bits, use enable, or
an OpAmp, its power level and mode, a follower or a regular OpAmp... Then you use
a wire tool to either connect it internal to other components and/or to pins. Then write code
for any component that needs real time changes, like a timers period or a clock change.
All components have an API library, so you just call those f()'s in your code to perform
tasks or read their results, like A/D. Here is whats onchip, in many cases multiple copies -
Excellent starter board, $ 15, CY8CKIT-059
There are tons of training videos but here is a couple of youtube starter videos :
A series of videos
Note PSOC has the capability using schematic capture and/or verilog to create custom components.
There is a library of user activity doing this, like DDS, CORDIC component, 74HC look alike logic components,
etc.. One can import these into your design catalog and use them. Great stuff.
An aside, here is an interesting analyzer for steppers (using
Raspberry Pi Pico)
