When configuring the STM32 Blue Pill timer module in encoder mode, the timer module works as a digital counter using two input signals. When both input pins have a valid transition, the counter gets clocked. The count pulses are generated by monitoring the sequence of the transitions of the ...

If "Enable Update Interrupt" is not selected in the case mentioned above, the Update interrupt will not be generated, and consequently, the LED will not toggle since the update interrupt is disabled. When the sample time of the constant block connected to the timer block's UG (Update ...
