Would like to know exactly what board you chose, so I can acquire one. I
have a cipher drive and an HP 88780A that would be good candidates to
use with this / use this to test. I also have a DG drive that might
well have a Pertec interface (haven't looked in a while).
Hi Jay,
The board I'm using is the STM32F4VE, described here:
https://stm32-base.org/boards/STM32F407VET6-STM32-F4VE-V2.0
Cheap and available; generally about $14-15 from Aliexpress.
I've toyed with the STM32H750 board (very similar, but runs at 400Mhz;
the added cost didn't contribute anything toward functionality.
Your DG might well be Pertec-interface, but you can check that out with
Bruce Ray.
Oh, a word of caution is in order... With the chip shortage, a lot of
Chinese vendors are re-labeling GDS32F407 and CKS32F407 chips with the
ST logo and markings. I've run into a few, but generally, they perform
as well as--and in some cases, better than, the real thing.
I'll put you on my mailing list...
All the best,
Chuck
