在Linux操作系统和ARM嵌入式实验系统环境下，分析linux下的键盘、LED驱动程序，编写一个应用程序，实现以下功能：在ARM开发板上按下数字键1、2、3时，对应启动模拟量AIN0、AIN1、AIN2采样，并把AD转换的结果从终端输出和LED显示。(Environment of the Linux operating system and ARM embedded experiment system, the Linux keyboard, LED driver, write an application, the following functions: ARM development board to press the number keys 1, 2, 3, corresponding to the start the analog AIN0, AIN1, AIN2 sampling and AD conversion results from the terminal output and LED display.)

It is well known that the production of hot coils in uniform thickness depends on various process parameters such as the material, the number of rolling stages, the reduction ratio of the thickness, the rolling speed, the front and back tensions, the friction between the material and rolls, the rolling temperature, and the rolling force at each stage of rolling. In the present study, the effect of front and back tensions on reducing the thickness deviations of hot rolled steel strips were investigated by developing a fuzzy control algorithm. In order to derive the fuzzy control rules, rigid±viscoplastic ® nite element simulations were carried out using the material property determined from the production data.

珠海杰里2系列开发包,可以学习一下，因为是otp的片子，如果要看效果需要原厂的仿真工具(zhuhai jieli tech，51 OTP )
