VC_ch341-i2c源码
应用背景CH341串口使用方法:
CH341实现USB转串口,在逻辑功能方面的使用方法与普通计算机串口相同。
与普通计算机串口的区别:
CH341提供的是仿真串口,所以不支持串口本身的纯硬件操作,例如I/O操作,
普通计算机串口是静态设备,而CH341串口是动态设备,理论上随时会断开,
CH341的附加功能(下面有介绍):读取外部串行EEPROM,支持更高波特率。
提供“模块调试”工具,启动后将“类型”选择为“手工输入发送”,
打开串口后就可以用于CH341串口或者普通串口的输入输出监控及收发调试。关键技术CH341连接24C0X,A2=A1=A0=GND,将仿真串口的波特率选择为300bps,
可以用串口监控/调试工具软件演示:
1、发出命令包,为4个十六进制数据: 40 A1 01 00
将24C0X中地址为01H的数据读出,可以从串口接收到一个字节的数据
2、发出命令包,为4个十六进制数据: 40 A0 2A 69
将一个字节的数据69H写到24C0X中地址为2AH的单元,通常等待10mS后才能进行下一个操作
3、发出命令包,为4个十六进制数据: 40 A5 E7 00
将24C0X中地址为02E7H的数据读出,可以从串口接收到一个字节的数据
注意,只有24C08和24C16中有地址为02E7H的数据单元

操作系统提供间
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.
