В след за примером идет график поясняющий работу, на нем видно, что счет ведется по обоим фронтам, а детектор фронтов должен срабатывать только по положительному(TIMx_CCER register, TI1FP1 non-inverted, TI1FP1=TI1)Figure 93 gives an example of counter operation, showing count signal generation and
direction control. It also shows how input jitter is compensated where both edges are
selected. This might occur if the sensor is positioned near to one of the switching points. For
this example we assume that the configuration is the following:
● CC1S=’01’ (TIMx_CCMR1 register, TI1FP1 mapped on TI1).
● CC2S=’01’ (TIMx_CCMR2 register, TI1FP2 mapped on TI2).
● CC1P=’0’ (TIMx_CCER register, TI1FP1 non-inverted, TI1FP1=TI1).
● CC2P=’0’ (TIMx_CCER register, TI1FP2 non-inverted, TI1FP2= TI2).
● SMS=’011’ (TIMx_SMCR register, both inputs are active on both rising and falling
edges).
● CEN=’1’ (TIMx_CR1 register, Counter enabled).
Объясните пожалуйста почему так?
