I believe MVB 001.4 in that 0x26 module is a field that lacks units; it's just a value with a range of 0 to 255.NETech: very interesting - I probably should know the answer, but what are the scales in the graph? Sorry, but graphs without axis descriptors is a pet-peeve of mine!!
Interesting. I suppose the potentiometer is connected to a VCC and the voltage on the cursor is read by an analogue-to-digital converter (one byte, values 0 to 255) with limits defined by the controller module. But if there is some dust on the potentiometer's resistive track it can make the cursor to lose contact with the track, then the voltage on the cursor can go momentarily to zero, even though it's a value out of range. Am I correct?Those kinds of position sensors are designed in such a way that the raw value never goes to the extreme end of the range (in this case, 0 or 255), and if it does, the control module interprets that as a malfunction.
Yep. Also a broken or shorted wire will be picked up as an out-of-range condition.Am I correct?
