...According to the sparse documentation of chip internals the output op-amp is indeed inverting and the DAC output is also (digital) inverted if buffer mode is selected...
Well spotted :idea: That could indeed explain it.

Looking forward to learn some ARM assembler on the pyboard too.
(don't worry for my mental health, I have written a lot of KLOCs of IBM/360, 6502, 8086, HP 2114B assembler in the past, it couldn't get worse)
Welcome to the wonderful world of compressed RISC instruction sets!
(Meaning: It will get worse :-))
