ds1302

proteus仿真，以LPC2138芯片为核心生成PWM波，控制升压斩波电路（PWM），实现稳定的高电压输出。包含AD转换、串口通信。(proteus simulation. This design use PWM wave generated by LPC2138 to control boost circuit and realized a steady high voltage output. ADC and serial port communication are involved in the design.)

说明：  一个特别好的modbus从机扫描程序，可以以RTU或ASCII方式通信以此来检验下位机。(A particularly good modbus slave scanner can communicate with RTU or ASCII way to test this lower position.)

基于VC++的，以操作文件的方式（CreateFile,WirteFile,ReadFile）来操作串口实现的射频卡门禁系统，实现了包括读卡写卡，寻卡防冲突等功能。(Based VC++ in order to manipulate papers (CreateFile, WirteFile, ReadFile) to operate the serial interface of the RF card access control systems, including the realization of the card reader to write, look for cards anti-collision function.)
