Tool/software:
Hi team,
customer wants use the device to achieve for detect MCU work or not.
could you help to check the schematic can work or not?
customer test the circuit but yellow waveform is going to High.
How to remove the Yellow signal because will cause MCU error detection
Hi Jimmy,
Which yellow high signal is the is the error?
From what I see, the device is working as intended.
Truth table as below
Circle 1: First trigger
Circle 2: The noise from the Ch2 (B input) is retriggering the output. (where is this noise coming from?)
Hi Jimmy,
Understood now. Circle 2 is wanted behavior.
If you only want the PWM signal to trigger, than you can also use a falling edge detect. However, you may need to rewire the signals. See the highlighted portion below.
Circle 1 is not a glitch, this is intended behavior. The MMV is detecting the rising edge and outputting a signal. As currently the device is in rising edge detect.
Hi Jimmy,
Can you zoom into this part of the signal? Your explanation leads me to believe that you have a very slow rising/falling edge.
