The trigger level is just a reference voltage, but the actual waveform has jitter at the edge. The following figure is a screenshot of a normal rising edge trigger:The blue T line is the reference vol...
I wrote a program to drive DS18B20 with CPLD and use LCD1602 for display. But it always displays 00.0. Can an expert take a look at my code to see if there is a problem? Thank you!...
