水位监测报警系统原理
<P>摘要：本水位监测报警器使用5V低压直流电源（也可以用3节5号电池代替）就可以对5~15厘米的水位进行监测，用LED显示和数码管显示水位，并可以对不再此范围内的水位发出报警。主要采用CD4066、74LS86、74LS32、CD4511芯片，再加上数码管、蜂鸣器、发光二极管、电阻这些器件组成一个简单而灵敏的监测报警电路，操作简单，接通电源即可工作。因为大部分电路采用数字电路，所以本水位监测报警
基于CH341A的USB串口通讯设计
<p>为解决当前计算机串行通讯接口只有USB，难以满足旧型号设备或某些单片机要求RS232通讯的问题，设计出两款RS232/USB电路。采用CH341A与MAX223集成电路芯片构建标准9线RS232/USB通用接口转换器，无需编程。采用CH341A与PIC16F877A构建单片机与计算机之间的USB通讯电路，软件遵循RS232通讯协议，硬件进行电平转换。实际使用表明，这两款产品与计算机端Wind
单片机Flash存储器坏块自动检测
在深入了解Flash存储器的基础上，采用单片机自动检测存储器无效块。主要通过读取每一块的第1、第2页内容，判断该块的好坏，并给出具体的实现过程，以及部分关键的电路原理图和C语言程序代码。该设计最终实现单片机自动检测Flash坏块的功能，并通过读取ID号检测Flash的性能，同时该设计能够存储和读取1GB数据。
