CPU卡在税控行业应用驱动,符合7816要求

资源描述STM32F103C8T76的SPI口读九轴传感器MPU9250数据，用JLink RTT打印传感器读出的数据。采用STM32CubeMX的图形界面软件配置STM32参数，初始化STM32芯片；采用SPI读取MPU9250的陀螺仪、加速度计、磁场计的数据；采用SWD口调试，利用JLink RTT打印读取到的陀螺仪、加速度计、磁场计的数据；修改了官网上的RTT程序的Bug（打印语句进入死循环）。

这是一个用Verilog编写的简单的处理器，虽然只有5条指令，通过这个例子，了解cpu架构，如何开发处理器，会很有启发性。

本系统利用集成智能温度传感器测量温度，采用光纤传输温度信号。系统由单片机（HT46R24）控制温度传感器（DS18B20）的温度采集。当有采集温度的指令的时候，才启动温度传感器并采回其数据，在没有进行温度采集的时候，将通过抬高温度传感器的地，关断其工作电源，如此可以降低系统的功耗。系统将每一次采集回来的数据与前一次的数据比较，若温度变化超限或温升超标，立即发送上述温度值；否则，累加到采集了一定的次数，再向主机发送最新温度值。-The system uses an integrated smart temperature sensors measure temperature, using optical fiber transmission temperature signal. System consists of microcontroller (HT46R24) controlling the temperature sensor (DS18B20) the temperature of collection. When a collection of instructions, when the temperature before start-up temperature sensors and taken back to its data, collected in the absence of the temperature when the temperature sensor will raise, the turn-off the power of their work, so you can reduce system power consumption. The system will come back every time collecting data and previous data comparison, if the temperature changes or temperature exceeding overrun immediately send the temperature value otherwise accumulate to collect a certain number of times, again

Linux 操作系统提供进程间通信（IPC）机制，用来保证正在执行的进程在内核的协调下能够 共享资源、同步以及交换数据等。Linux 支持大量进程间通信机制，包括信号、等待队列、管道 以及Unix 系统V 中提供的进程间通信机制，如消息队列、信号量和共享内存。-Linux operating system to provide inter-process communication (IPC) mechanism used to ensure that the process is being implemented in coordination with the core to share resources, synchronization and exchange information. Linux support a large number of inter-process communication mechanisms, including signal and wait for the queue, pipeline and the Unix System V to provide inter-process communication mechanisms, such as message queue, the signal volume and shared memory.
