RL-DAC

Finally updated RL-DAC after a while.

Although completely useless because of it’s very narrow use. Consider yourself warned 😛 Still, if fiddling with resistor ladder DAC’s your thing (it’s actually not mine), I suppose it might be of some limited use. Beware it also can be somewhat quirky, and it does take a few seconds to start from within the Processing environment (I use processing 1.5.1 running on a dual-core AMD64x2, 2.5 GHz thing with 4 GB RAM, that about covers it I think).

Introduction:

Once again, a thread from the Arduino forum, this time the 2-cent DAC thread from forum user “raalst” inspired me to follow up on a thought I got – to utilize the high-Z state of the digital outputs for an increased resolution of a resistor ladder / network type DAC.
