采用STM32F429单片机连接摄像头采集图像，并附源码(STM32F429 MCU is used to connect camera to collect image, and source code is attached.)

i2c总线的程序设计，可以实现信息传输，是总线的一种(i2c bus program design, you can realize information transmission, is a bus)

超声波定位通过头文件封装进行函数调用获得实时位置信息，方便高效。(Ultrasound positioning)

this code used to calibrate the touch of tcb8000c TFT screen with pic 18f4620 micro controller

vpn auto linker dont dl just testing :d

关于STM32F407的IIC总线操作，用IO口模拟总线时序，以及AT24C64的驱动编写。(The IIC bus operation on STM32F407 with analog IO bus timing, and write AT24C64 drive.)

基于STC15f2k60s2的IIC通信，软件模拟IIC接口，主机和从机代码(Based on the IIC communication of STC15f2k60s2, the software simulates IIC interface, host and slave codes)

说明：  单片机驱动3310 lcd显示屏的c程序，单片机与屏的线路连接可以参见程序中的宏定义。程序写得很精简，但是很好用。(Microprocessor 3310 LCD display c procedures, SCM and the screen can see the line connecting the procedures macro definition. Very streamlined procedures, but is useful.)

超声波测距资料(HC-SR04)_TB参考文档及原理图源程序(Ultrasonic Ranging Data (HC-SR04) _TB reference documentation and schematic source)

开机自检、去皮、计价、清零、中文液晶显示等； 从上述中可以看出，本设计的主要思路是利用压力传感器得到重量的变化并且将重量的变化经过电压放大电路经过，A/D转换器将模拟量变换为数字量，单片机可以顺利的读取，并且将得到的信息进行采集后计算。通过累加之后的方式将物品的重量和价值总额，通过显示电路显示出来(Self-check, peel, price, clear, Chinese liquid crystal display and so on; It can be seen from the above, the main idea of this design is the change of the pressure sensors are used to get the weight and the weight change after the voltage amplification circuit, A/D converter analog conversion into digital quantity, single chip can be read smoothly, and to get information from the acquisition after calculation. The weight and total value of the item are displayed by means of the display circuit.)
