Hi,
I am using a counter to count the quadrature output of an incremental rotation/angle encoder (its an LM15 type from RLS). The encoder is connected to FIO0 and FIO1. I use the following settings:
DIO0_EF_ENABLE = 1DIO1_EF_ENABLE = 1
DIO0_EF_INDEX = 10
DIO1_EF_INDEX = 10
The number of counts per rotation is known to be 48000, I want the counter to automatically resets when it reaches this number. Usually in microcontrollers, this can be set in the form of an auto reload value. Does the T7 feature a similar feature? If so, what are the associated registers?

We do not support a zero-on-compare feature. Some options:
1. Do a modulus divide by 48000 in your software or during post-processing.
2. Do the zero-on-compare in a Lua script. Might be tough if you counts are too fast.
3. Do a modulus divide by 48000 in a Lua script and store the result in user-ram. Then read that user-ram rather than the dio-ef value.
4. If your encoder has z-phase use that to zero the count (quadrature mode).
