Hi everybody!Recently I found a strange phenomenon that there was a peak on the rising edge when I using the TIM1's 4 chanels to be PWM output mode.And the maxium peak voltage can reach to 5.6V measured by the oscilloscope.But the maxium voltage supplied for the MCU was just 3.45V measured by the same oscilloscope.
So where was the 5.6V peak voltage from?Please help me!
4.Timer Mode:PWM output mode
7.PWM driver load:No load
8.PWM output pin configuration:GPIO_Output_AF_PP
