Hi Jeff,If the frequency of the raw data signals (ChA, ChB) from the US Digital encoders is low enough, then the software quadrature decoding mode of the WheelCommander can be used. This is another new feature we are working on, in addition to providing programmable encoder resolution.
When we are ready to ship this firmware update, we will provide maximum allowed frequency information. But our rough estimate at this time is that we should be able to handle between 1000 and 10,000 pulses per second, including rising and falling edges of each channel. So, that would equate to between 250 and 2500 encoder lines per second maximum. If the US Digital encoder is on the motor shaft before the gear train (or belt drive?), it may be too fast for our system to function, depending on the resolution of your encoder (in your case, 256) and the RPMs of the motor.
Please explain what rotation rate you expect the encoder to run at. Sincerely, Pete Skeggs Nubotics Tech Support
