Description

TLU trigger inputs thresholds are controlled via 2 DACs. It'd be nice if thresholds could be set in units of Vs, rather than using raw integers being written into the DAC registers.

DAC datasheet: https://www.mouser.co.uk/datasheet/2/609/AD5625R_5645R_5665R_5625_5665-877198.pdf

Research direction

No files, tests, or entry points are named. Start by locating the TLU trigger-input threshold configuration and the DAC register writes, then consult the linked AD5625R/AD5645R/AD5665 datasheet. Done means thresholds can be specified in volts rather than raw DAC register integers.
