Embodiment 1
[0010] Embodiment 1, with reference to figure 1 , Figure 5 : MCS-51 series single-chip microcomputer is used as the microprocessor, and the microprocessor is used as the control unit to output digital signals to the D / A converter, which can generate pulse waveform output. Relevant information is stored in the program memory and the external memory, and real-time display is realized through the driving circuit and the display. The adjustment button is also connected to the controller to adjust the signal amplitude. The hardware part is divided into three parts according to the performance of the machine: 1. Pulse waveform generation module, corresponding hardware part: CPU, EPROM, RAM, D / A converter, crystal shock (clock), address latch, amplifier circuit (LM747 Transistor) and the corresponding peripheral capacitors. 2. Display module, corresponding hardware parts: CPU, EPROM, RAM, crystal shock (clock), address latch, LCD display, LCD display peripheral circuits. 3. Keyb...
