configuration as above except TIM_CC1P = 1).
Figure 40. Example of encoder interface mode with IC1FP1 polarity inverted
The timer configured in encoder interface mode provides information on a sensor's current
position. To obtain dynamic information (speed, acceleration/deceleration), measure the
period between two encoder events using a second timer configured in capture mode. The
output of the encoder that 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.
Do this by latching the counter value into a third input capture register. (In this case the
capture signal must be periodic and can be generated by another timer).
Timer input XOR function
The TIM_TI1S bit in the TIM1_CR2 register allows the input filter of channel 1 to be
connected to the output of a XOR gate that combines the three input pins TIMxC2 to
TIMxC4.
The XOR output can be used with all the timer input functions such as trigger or input
capture. It is especially useful to interface to Hall effect sensors.
