STM32 SPI口的应用例程，可是设置成主模式或者从模式。(STM32 SPI routine application of the mouth, but set to master mode or slave mode.)

单片机用P1口显示红外遥控器的按键值，单片机的应用(Display the key value of the infrared remote control, microcontroller MCU with P1 port)

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)
