- Making a cheap 1M SPI Rom Emulator 8 second to copy from parallel to SPI re-Program STM Serial Flash M25P10 by reading 29010 parallel ROM Running on standard 8051 32 I/O, a TTL 7407 as bus switch. Total
74LS07
- 7407大电流供应，最大能有30ma，可以驱动电压高达30V，是理想的常用驱动芯片
多路数据采集
- 以ADC0809和8051为核心，该系统有三个部分：数据采集，数据处理和显示，终端接收。具体包括控制、显示、A/D转换器、电平转换接口、个人计算机等。设计中用ADC0809进行8路数据的采样，利用MCS-51单片机的串行口发送和接收数据。显示部分由8155、75452、7407和LED数码显示器构成。硬件设计应用电子设计自动化工具，软件设计采用模块化编程方法。
