IssuesCurrent mirror sources
current. Need to connect Iref calib. resistors to
VDDA!
DAC CS signal also used to load register. Pin can not be
connected to GND (bend away) and needs to be connected to a
specific pin of the VHDCI connector.
1.2V LED will not light up, as forward voltage is not
high enough.
