模拟串口C51编程-simulation C51 Serial Programming

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.

本模拟I2C软件包包含了I2C操作的底层子程序，使用前要定义好SCL和SDA。在标准8051模式(12 Clock)下,对主频要求是不高于12MHz-The simulation package includes I2C bottom I2C operation subroutine, before the definition of a good use of SCL and SDA. 8051 in standard mode (12 Clock), the requirements for the frequency is higher than 12MHz

不但了解单片机，还能够使单片机更稳定地工作，对制版也有一定价值。-not understand microprocessor, microcontroller also enables more stable work, Myrtle has a certain value.
