Help with 360 wheel encoder to UHID

Pages: << < (5/5)

PL1:

Two more things to consider:

1. From the UHID manual:
Note that only certain pins can be configured for quadrature devices. These can be seen in U-Config by clicking on the "Quadrature" line in the PCB image. Appropriate pins will be highlighted.

2. Are you sure the "reverse" should be clicked on the second pin?

Edit: Double checked.  J4 and J5 pins are OK for Quadrature inputs.

BadMouth:

With the encoder powered by the UHID, do the signal wires output 5v pulses when you turn the wheel by hand?

Yes that's the most important check.

I would think either one or both of the sensors is not working, or the sensors are wired in such a way that instead of pulling the signals to ground (the U-HID pins have pull-up resistors), they are pulling them to 5 volts which would not work. If this is the case this is fixable but might need some hacking of the sensor PCB tracks.

Hey Andy, Ive just emailed you this:-

Thanks for the quick reply.

The UHID is out putting 5.01v. When connected to the optic it drops to 4.63v measured from the power pins. When rotated both X1 & X2 pins fluctuate squarely between -0.3v to 4.63v alternating between them. I am 100% sure everything is connected correctly and the UHID is programmed correctly. I am on Firmware 1.3. Please see below.


I am happy to replace the optic boards with recommended ones if you have any. I notice the happ ones seem to work well but cant find any in the UK.
