此为基于PT2272的无线接受程序，经过实验,可行.

* 功能：运行WDT，并控制数码管D1显示输出。程序开始先对数码管D1全闪烁控制，并进行喂 * 狗处理；然后显示 - ，并进入死循环，等待WDT复位。-* Function: Run WDT, and control D1 digital tube display. The beginning of the proceedings of the first all-digital pipe D1 flicker control, and deal with dog-feeding* then display- and to enter the infinite loop, waiting for WDT reset.

自己写的 STM32F10x的ADC和Timer驱动, 没有使用固件库。每秒通过串口UART输出当前ADC值。 应用范围: 因为不涉及IO口,所以此工程在STM32F1xx的任何主板上都可以运行。 编译器: IAR ARM 4.42A。 作者: w123456xy@sohu.com 15189792379。 -Write your own STM32F10x the ADC and Timer-driven, not using the firmware library. Second serial UART output current through the ADC value. Application scope: because they do not involve IO port, so this works on any STM32F1xx motherboard can run. Compiler: IAR ARM 4.42A.

51单片机的KEIL操作函数库，这个资料看完了，那么KEIL开发51的使用也差不多了。-51 SCM KEIL operation library, read this information, then use the KEIL development of 51 should be enough.

SPI是一个环形总线结构，由ss（cs）、sck、sdi、sdo构成，其时序其实很简单，主要是在sck的控制下，两个双向移位寄存器进行数据交换。 假设下面的8位寄存器装的是待发送的数据10101010，上升沿发送、下降沿接收、高位先发送。 那么第一个上升沿来的时候 数据将会是sdo=1；寄存器=0101010x。下降沿到来的时候，sdi上的电平将所存到寄存器中去，那么这时寄存器=0101010sdi，这样在8个时钟脉冲以后，两个寄存器的内容互相交换一次。这样就完成里一个spi时序。 -SPI bus is a ring structure, by ss (cs), sck, sdi, sdo composition, its timing is actually very simple, mainly under the control of the sck and two bi-directional shift register for data exchange. Assuming the following 8-bit register is loaded to send the data to be 10,101,010, rising to send, receive falling edge, high first sent. Well, the first rising edge to the time data will be sdo = 1 register = 0101010x. Falling edge comes, sdi on the level will be stored to the register, then register at this time = 0101010sdi, so 8 clock pulse later, the contents of two registers to exchange time. This will be completed in a spi timing.
