configuration as above except CC1P=1).

The timer, when configured in Encoder Interface mode provides information on the sensor's

current position. You can obtain dynamic information (speed, acceleration, deceleration) by

measuring the period between two encoder events using a second timer configured in

capture mode. The output of the encoder which indicates the mechanical zero can be used

for this purpose. Depending on the time between two events, the counter can also be read

at regular times. You can do this by latching the counter value into a third input capture

another timer). when available, it is also possible to read its value through a DMA request

generated by a Real-Time clock.
