PWM-out

通过小键盘的输入来控制输出的演示 设计要求：按下“A”键时，在七段数码管各位上循环显示“8”；按下“B”键时，在发光二极管上绿色、黄色、红色灯管依次循环定时点亮；按下“C”键时，退出，在七段数码管上显示“P”。 (Through the keyboard input to control the output of the demonstration)

说明：  基于16位ADC，AD7705的称重系统设计，以单片机89s52为数据处理和控制模块，1602为显示模块(Precision Weigh Scale Design Using the AD7192, 24-Bit Sigma-Delta ADC with Internal PGA, as AD converter and MCU 89s52 as data processer and controller)

51单片机ADC0832+LCD1602 proteus 仿真源程序，包括proteus原文件，可以直接仿真。在keil+proteus 7.8上测试通过。(51 MCU ADC0832+ LCD1602 proteus simulation program, including proteus original documents can be directly simulated. In keil+ proteus 7.8 on the test.)

说明：  对一路工频交流电（频率波动范围为50 ±1Hz、有失真的正弦波）的电压有效值、电流有效值、有功功率、无功功率、功率因数进行测量的数字式多用表。通过LCD12864显示(Frequency of the AC all the way (the frequency of fluctuations in the range of 50 ± 1Hz, there is distortion of the sine wave) RMS voltage, RMS current, active power, reactive power, power factor measurement of the digital multimeter. LCD12864 show through)

高性能RF模块，硬件使用STM32F103和CMT2300A（射频芯片），软件 基于contiki操作系统和cxmac协议。(High performance RF module, hardware using STM32F103 and CMT2300A (radio frequency chip), software based on Contiki operating system and cxmac protocol.)
