Datapixx(‘SetDinDataOutStrength’, strength);

Although DIN is primarily intended to be a digital _input_ system, it is
possible to turn around these I/Os, to drive outputs at up to 3.3V.
SetDinDataOutStrength offers coarse control over the output drive strength. One
application is controlling the intensity of illumunated response buttons.
-“strength” should be within the range 0-1. The actual implementation varies
drive strength from minimum to maximum in increments of 1/16 of full strength.
See DatapixxDin*Demo files for examples.
