NT7538

这是一个有关AD7689的程序，只有驱动部分，使用的CPU是msp430F149。可以采集8路数据。不过数据在主程序中需要处理下，不然会有波动。(This is a program about the AD7689, only the driving part, CPU use is msp430F149. 8-way data can be collected. However, the data need to be addressed in the main program, the otherwise subject to fluctuations.)

STM32F103RB USB模拟串口范例，参考官方版本，改写双缓冲+环型队列接收，改写环节队列发送。工程开发环境为COOCOX IDE。(STM32F103RB USB virtual serial port example, refer to the official version, rewritten double buffering+ ring queue receiver, rewritten ring queue to send. Development environment for COOCOX IDE.)

51单片机的模拟串口的一个小程序，新手了解学习模拟串口看一下可以(51 SCM simulation serial port a small program, novice understand the learning simulation serial port to see can)

STM32外扩4*4矩阵键盘，包含原理图及源码。(STM32 extends 4*4 matrix keyboard, including schematic diagram and source code.)

能够进化模拟电路，同时更改参数设置可以进化自己想要的东西(To evolve analog circuits, parameter settings can also change the evolution of what she wants)

160160程序,160160模块电表使用比较多,供参考(160 160 procedures, 160 160 more modules to use the meter, for reference)

说明：  通过51单片机控制驱动芯片298控制两个步进电机画圆的程序(From 51 single-chip control two stepper motors to draw the program)

DS18B20温度测量，上下限温度设定测量（超出报警）(Upper and lower limits of temperature measurement (in excess of the police))

8个单片机小程序，对串口、中断的学习很好理解。(8 SCM applet, the serial interrupt learning well understood.)

说明：  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.)
