这篇报告介绍了关于PIC单片机原理与应用。主要有以下几方面内容：1 利用PIC单片机的PC计数器及实时计数器计数或计时，利用LED数码管显示数据。 2．利用PIC单片机进行各种信号、数据的采集。 3．利用单片机的控制功能实现控制。 4．了解其硬件上各引脚输入输出口，充分掌握其各个指令和基础编程，以及一些简单的应用。 5．利用EEPROM实现单片机的数据掉电保存及利用I2C模式进行通讯。 -This report describes the PIC microcontroller on the Theory and Application. Mainly the following aspects : the use of a PIC microcontroller and the real-time counter PC Counting or time, use of digital LED display data. 2. PIC for the use of the signals, and data acquisition. 3. Microprocessor control functions to achieve control. 4. Understanding of the various hardware input and output pins I fully understand the basis for all orders and programming, and some simple applications. 5. MCU use EEPROM data preservation and the use of power-down mode I2C communications.

视觉暂留，编程从一个I/O口输出一扫频信号，驱动一支LED灯闪动，频率范围为10HZ~99HZ，扫描时间为30秒，在LED闪动期间观察，一旦发现无法识别LED灯闪动时，按下按键K1，立即停止输出，并将此时的信号频率显示在数码管上，该信号的周期为测试者的视觉暂留时间。-Persistence of vision, programming from an I/O port outputs a sweep signal to drive an LED light flashing, the frequency range of 10HZ ~ 99HZ, scan time of 30 seconds, the LED flashing during the observation, once found it impossible to identify the LED lights flashing, press the key K1, immediate cessation of the output, and at this time the signal frequency displayed on the digital control on the test cycle of the signal" s persistence of vision time.
