这个资料主要讲述Keilc51的使用，及代码程序的优化(This information focuses on the use of Keilc51, and code optimization process)

CPU正在执行一项任务A，然后突然停止任务A去执行任务B，执行完任务B再回来继续执行任务A的过程。(CPU is performing A task. A, then suddenly stop tasks to perform A task B, perform the task B come back again continue to perform the task A process.)

说明：  STM32 的GPIO操作示例程序代码, 试用与Keile环境STM32F103代码(STM32 GPIO operation code)

AVR 单片机嵌入式开发源程序，对新手入门有很有帮助。(AVR embedded development program, Getting Started with helpful.)

说明：  关于stm32的高级应用部分代码历程，stm32的代码。(About STM32 advanced application part of the code process.)

测量单片机频率，可以测量周期波的频率，最大可以测到60khz(Measuring Frequency of Single Chip Microcomputer)

以1/10秒为单位，向电脑串口发送数据。同时，在P2口上以2进制形式显示发送的数字。可作为调试的工具。(Send a number to the computer s COM port, for each 0.1 second. while display it on port P2.)

基于stm32的无刷直流电机驱动程序，带LCD显示和按键程序。TIM1产生PWM驱动电机，TIM接受电机的霍尔。(BLDC motor based on stm32, with LCD display and key procedures. TIM1 generates PWM drive motor, TIM accepts the hall of the machine. )
