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 ...

中断(Interrupt):当捕获事件发生时,定时器会触发相应的中断,可以在中断服务程序中处理捕获结果。 频率测量 测频法:在闸门时间T内,对上升沿计次,得到N,则频率f_x=N / T. 这种方法要求测量的频率比较快,计算频率的N越多,计算的越精确,也就表明频率越快; ...
