Has anyone wired up an ILDA laser galvo X-Y projector using Gadgeteer hardware?
ILDA is an analog bipolar differential voltage signalling system. Two wires, ranging -5V to +5V each, combined differential voltage ranging from -10V to +10V.
The 10 bit DAC on most analog out pins seems to fall short for this application - only 1024 levels = only 1024 scanlines. Is there a way to “finesse” more resolution, perhaps as an artifact of the differential between two pins? (2 x 1024 is better than 1 x 1024) Or are there higher resolution DAC modules available somewhere?
