ii2读写pcf8591，基于stm32f10xzet6，pcf8591模块，实现热敏电阻转换(ii2 read/write pcf8591)

说明：  使用128AVR单片机测量三相电的电压，电流，频率等数据并通过12864显示屏进行实时显示(Using 128AVR MCU to measure the voltage, current and frequency of three-phase electricity and display them in real time through 12864 display screen.)

Very hard to find Texas Instruments software (ADP.exe) for calculating circular and rectangular coils for RFID application (13.56Mhz and 125kHz). Software is very accurate. Software is 16-bit, so it must be run on Windows XP (not compatible with Windows 7)
