直流电机速度控制 可通过按键来选择转速在LED上显示 使用的是C8051F 单片机-DC motor speed control through the keypad to select the speed in the LED display using a single-chip microcomputer C8051F

用89C2051实现AD转换的C51程序-with 89C2051 AD conversion procedures C51

串口通讯的上位机软件,希望你能用的上,是用V++写的,-The host computer serial communication software, I hope you can use the upper, is written in V++, thank you

自己keil C51写的X25045驱动，调试通过-their written X25045 driven through debugging

51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。-51 on the RTOS, the RTOS non-preemptive multitasking operating system, if the user of the longest task execution times smaller than system beats time, it is superior to the MiniRTOS Preemptive 200040. Because of the small resources MiniRTOS occupation, RAM no more than 20 bytes, procedures only for the space of more than 600 bytes.

功能描述： 利用AT89S51单片机的T0、T1的定时计数器功能，来完成对输入的信号进行 频率计数，计数的频率结果通过8位动态数码管显示出来。要求能够对2－40KHZ 的信号频率进行准确计数，计数误差不超过2/1-Functional Description: Using AT89S51 MCU T0, T1 timing counter function, to complete the input signal frequency counting, counting the frequency of 8 resulted in the adoption of dynamic digital tube display. Request to the 2-40KHZ signal frequency accurately count, counting error of less than 2/1
