This design completes the design and implementation of a simple digital signal timing analysis device. A simple digital signal timing analysis device is composed of STM32 MCU as the main control unit. Digital signal generator is mainly composed of 8-bit counter, multiplexer, shift register and 8-bit dial switch to realize cyclic TTL level. Simple digital signal timing analysis device consists of sawtooth wave generator, step wave generator, adder circuit and DA output module. It can collect 8 logical signals and set the position of trigger time of waveform. When the trigger condition is specified, the measured signal can be collected, stored and displayed on the oscilloscope.
