对于PCB LAYOUT工作者,做元件库这是一本非常好的参考资料.(PCB LAYOUT for workers, to do component library This is a very good reference.)

说明：  使用STM32驱动ADS1118，电压采样信息打印到串口上(STM32F103--->ADS1118)

stm32 串口1为蓝牙 串口2、3、4、5读取4个JY901九轴陀螺仪模块(STM32 serial 1 for Bluetooth serial 2, 3, 4, 5 read 4 JY901 nine axis gyroscope module)

ov7670 datasheet，ov7670摄像头数据手册(this is the ov7670 datasheet)

说明：  设计一个VI来测量温度（保留2位小数），每隔0.25秒测一次，共测定10秒。在数据采集过程中，VI将在波形Chart上实时地显示测量结果。采集过程结束后，在Graph上画出温度数据曲线,并且把测量的温度值以文件的形式存盘， 使用记事本打开文件检查结果是否正确。 存盘格式为： 点数 时间(S) 温度值(度) 1 0.25 78.56 2 0.50 85.32(Design a VI to measure the temperature (keep two decimal places), measured once every 0.25 seconds, 10 seconds were measured. In the data collection process, VI will display the measurement results in real time on the waveform Chart. After the acquisition process, the temperature data in the Graph draw curves, and the temperature measured in the form of document archiving, Use Notepad to open the file to check the result is correct. Save format: Points Time (S) temperature (degrees) &nbsp 1 0.25 78.56 &nbsp 2 0.50 85.32)

本实验将实现如下功能：开机的时候先检测SD卡和SPI FLASH是否存在，如果存在则获取其容量，并显示在LCD上面（如果不存在，则报错）。之后开始USB配置，在配置成功之后就可以在电脑上发现两个可移动磁盘。我们用DS1来指示USB正在读写，并在液晶上显示出来，同样，我们还是用DS0来指示程序正在运行。(This experiment will achieve the following functions: when booting, first detect the existence of SD card and SPI FLASH, and if there is, obtain its capacity, and display it on the LCD (if not, report an error). Then the USB configuration is started, and after the configuration is successful, two removable disks can be found on the computer. We use DS1 to indicate that the USB is reading and writing, and display it on the LCD. Similarly, we use DS0 to indicate that the program is running.)

说明：  直接频率合成仿真源程序,希望有人能用到.(Direct frequency synthesizer simulation source code, hope someone can use to.)

7279的程序 是在lpc2138上的经过调试绝对好使(7279 program in lpc2138 absolutely so on through the commissioning)

两个12V的电机驱动履带式底盘完成到制定目标运动的任务，可以通过点触屏进行无线控制。(Two 12V motor-driven crawler chassis complete the task of setting the target motion, which can be controlled by wireless touch screen.)

这是一个基于AVR单片机的3510i彩色液晶显示图片的范例(This is a based on the AVR MCU 3510i Color LCD picture examples)
