The PPMC driver has not been upgraded to conform to the pure canonical encoder standard. But, it does provide RAW velocity, called "delta". The HAL pin ppmc.0.encoder.03.delta gives the change, in pure encoder count units, per servo cycle, of the encoder connected to axis 3 of the unit. Since this is likely to be fairly coarse resolution, you probably want to either average it over some number of servo cycles, (should be a HAL component that already does that), or sum it up over some number of servo cycles and then scale to produce a less frequent, but more finely resolved value. I think you'd need to code up a new HAL component to do that.
