实验器材: 探索者STM32F4开发板 实验目的: 学习单色OLED显示屏的使用 硬件资源: 1,DS0(连接在PF9)  2,ALIENTEK 0.96寸OLED模块(连接IO说明,见oled.h文件)  实验现象: 本实验利用开发板的OLED/CAMERA接口连接ALIENTEK OLED模块，实现OLED模块的显示，下 载成功后，通过把OLED模块插入开发板左下角的OLED/CAMERA模块接口，按下复位之后，就 可以看到OLED模块不停的显示ASCII码和码值。  注意事项:  1,开发板的OLED/CAMERA模块接口比OLED的插针多2个,OLED靠左插即可. 2,例程默认用的8080方式驱动OLED模块,所以OLED模块的BS0,BS1都需要接VCC(默认接的VCC).  一、主要程序代码如下 int main(void){    u8 t=0; short temperature; Stm32_Clock_Init(336,8,2,7);//设置时钟,168Mhz  delay_init(168);   //延时初始化   uart_init(84,115200);  //初始化串口波特率为115200  LED_Init();     //初始化LED  OLED_Init();    //初始化OLED  DS18B20_Init();     //DS18B20初始化  OLED_ShowString(0,10,"Temperature:",12); OLED_ShowString(85,10,".",12); OLED_ShowString(98,10,"C",12); OLED_Refresh_Gram();//更新显示到OLED   while(1)  {    if(t%10==0)//每100ms读取一次  {              temperature=DS18B20_Get_Temp();    OLED_ShowNum(72,10,temperature/10,2,12); //显示正数部分          OLED_ShowNum(89,10,temperature%10,1,12); //显示小数部分          OLED_Refresh_Gram();//更新显示到OLED     }          delay_ms(10);  t ;  if(t==20)  {   t=0;   LED0=!LED0;  } }}

说明：  倒立摆，Inverted Pendulum ，是典型的多变量、高阶次 ，非线性、强耦合、自然不稳定系统。倒立摆系统的稳定控制是控制理论中的典型问题 ，在倒立摆的控制过程中能有效反映控制理论中的许多关键问题 ，如非线性问题、鲁棒性问题、随动问题、镇定、跟踪问题等。因此倒立摆系统作为控制理论教学与科研中典型的物理模型 ，常被用来检验新的控制理论和算法的正确性及其在实际应用中的有效性。从 20 世纪 60 年代开始 ，各国的专家学者对倒立摆系统进行了不懈的研究和探索。(Inverted pendulum is a typical multivariable, high order, nonlinear, strongly coupled and naturally unstable system. The stability control of inverted pendulum system is a typical problem in control theory. Many key problems in control theory can be effectively reflected in the control process of inverted pendulum, such as nonlinear problem, robustness problem, servo problem, stabilization, tracking problem, etc. As a typical physical model in the teaching and research of control theory, inverted pendulum system is often used to test the correctness of new control theory and algorithm and its effectiveness in practical application. Since the 1960s, experts and scholars from all over the world have made unremitting research and Exploration on the inverted pendulum system.)
