So if, as an example, you wire a potentiometer to p4_aux, when the pot. is all the way down, p4_aux=127. when it's a little higher, p4_aux=0.
also, 127 appears in it's "normal" position (midway 'round). So you can't just put in an if statement.
I hear this is by design. So watch out! |
This is designed this way, I asked the people at Innovation First they said when there is 0 volts on the input, the default is 127. We tested ours and voltage level of 0.3 or so will get you 0 for that input less than that voltage and results vary. We are using 15K pots with 560 ohms feeding the ground side of two pots. Ie 7.5 k in series with the 560. Hope this helps.
