(1) design and implementation of an alog bandwidth of 400Hz ~ 3000Hz simple digital storage oscilloscope. (2) requires the application of the input signal amplitude is 0 ~ 5V, 8-way with gated switch A/D converter data acquisition device 0808, 128 × 64 full dot matrix LCD module TG12864E shows the input signal waveform. (3) requests can be controlled by the microcontroller frequency, amplitude step, to a good display on the LCD display module range of 0 ~ 5V, waveform display can automatically refresh, can also be manually refreshed.
