应用背景在网上看到了相应算法，用stm32 编程出来与大家分享，网上很少有这资源，可以用在stm32细分控制步进电机，在转速低时，噪声小，也更为精确，等同于步进电机驱动器关键技术SPWM算法，以及用stm32仿真三角波。说实话网上很少用stm32中央对齐方式仿真三角波的，但是在DSP上很是普遍，所以这也是我分享出来的原因之一。

这个例子如果运行,将在仿真的PC窗口中的第1,2,3行显示一些信息后,在随机位置显示 1 ~ 5 .由于keil c51默认不支持重入函数,它的重入函数使用仿真的重入栈而不使用系统栈,而Small RTOS 51没有进行重入栈管理,所以在TaskA~TaskE虽然及其相似,但不能合并. (2)编译时会有5个警告,其中一个是因为没有使用一个系统函数OSSendSignal引起,它可以忽略.另4个是禁止任务间变量覆盖分析引起,必须忽略.感谢网友John X. Liu,在这个例子中我使用了他编写的仿真(dllPc51Emu.dll),这个dll原来是为他移植的Ucos-ii for keil c51的例子编写.-If you are running this example, will the PC emulation window, the first 1,2,3-line display some information, at random locations show " 1 " ~ " 5" . Keil c51 as the default does not support the re-entry function, which re- into the function of the weight stack instead of using the simulation using the system stack, while the Small RTOS 51 not been re-stack management, and so TaskA ~ TaskE though its similar, but not combined. (2) compile-time there will be five warnings, One of them is because there is no cause to use a system function OSSendSignal, it can be ignored. The other four are prohibited between the variables covered analyze the task to be ignored. thank User

ATmega8 taillight circuitA more complex C program that implements different flashing patterns under the control of both the push buttons and potentiometer. Use your imagination to come up with some novel ideas here. Remember however that more marks are to be awarded for the quality of the code than for the novelness of the patterns.
