Mitchell's culture shock will be going back to him to arrive Sep 12th.  I'm going to be doing 3D enclosure design
with FreeCAD meanwhile.  I'll take a look at the ST reference manual and line out the code needed for reading the output volts
as it builds up.  Scope photo attached shows build up in  0.1msec  (100 microseconds) with a 39k load resistor on the output.

It's fairly easy to ramp up so fast you have difficulty stopping the pulses in time if just using a level control algorithm.
But I get ahead of myself...
