1. Serial Type
1.1. 物理接口形式
- UART接口：
通用异步收发器（Universal Asynchronous Receiver/Transmitter)，UART是串口收发的逻辑电路，这部分可以独立成芯片，也可以作为模块嵌入到其他芯片里，单片机、SOC、PC里都会有UART模块。 - **COM口：**特指台式计算机或一些电子设备上的
D-SUB外形(一种连接器结构，VGA接口的连接器也是D-SUB)的串行通信口，应用了串口通信时序和RS232的逻辑电平。 - **USB口：**通用
串行总线，和串口完全是两个概念。虽然也是串行方式通信，但由于USB的通信时序和信号电平都和串口完全不同，因此和串口没有任何关系。USB是高速的通信接口，用于PC连接各种外设，U盘、键鼠、移动硬盘、当然也包括“USB转串口”的模块。（USB转串口模块，就是USB接口的UART模块）
1.2. 逻辑电平形式
-
**TTL：**TTL指双极型三极管逻辑电路，市面上很多“USB转TTL”模块，实际上是“USB转TTL电平的串口”模块。这种
信号0对应0V，1对应3.3V或者5V。与单片机、SOC的IO电平兼容。TTL电平：全双工（逻辑1: 2.4V–5V 逻辑0: 0V–0.5V）.
常见的USB转TTL芯片有CH340、PL2303、FT232、CP2102等[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-m9OMxVMV-1671375438990)(null)]
-
**RS232：**是电子工业协会(Electronic Industries Association，EIA) 制定的
异步传输标准接口，同时对应着电平标准和通信协议（时序），其电平标准：+3V～+15V对应0，-3V～-15V对应1。rs232 的逻辑电平和TTL 不一样但是协议一样。RS-232电平：全双工（逻辑1：-15V–5V 逻辑0：+3V–+15V).
232芯片用于5V单片机，3232芯片用于3.3V单片机。
-
**RS485：**RS485是一种串口接口标准，为了长距离传输采用差分方式传输，传输的是差分信号，抗干扰能力比RS232强很多。两线压差为-(26)V表示0，两线压差为+(26)V表示1
RS-485：半双工、（逻辑1：+2V–+6V 逻辑0： -6V—2V）这里的电平指AB 两线间的电压差。
2. Serial Class-pyserial
ser=serial.Serial("/dev/ttyUSB0",9600,timeout=0.5) #使用USB连接串行口
ser=serial.Serial("/dev/ttyAMA0",9600,timeout=0.5) #使用树莓派的GPIO口连接串行口
ser=serial.Serial(1,9600,timeout=0.5)#winsows系统使用com1口连接串行口
ser=serial.Serial("com1",9600,timeout=0.5)#winsows系统使用com1口连接串行口
ser=serial.Serial("/dev/ttyS1",9600,timeout=0.5)#Linux系统使用com1口连接串行口
- 属性
name:设备名字
port：读或者写端口
baudrate：波特率
bytesize：字节大小
parity：校验位
stopbits：停止位
timeout：读超时设置
writeTimeout：写超时
xonxoff：软件流控
rtscts：硬件流控
dsrdtr：硬件流控
interCharTimeout:字符间隔超时
- 方法
ser.isOpen()：查看端口是否被打开。
ser.open() ：打开端口‘。
ser.close()：关闭端口。
ser.read()：从端口读字节数据。默认1个字节。
ser.read_all():从端口接收全部数据。
ser.write(“hello”)：向端口写数据。
ser.readline()：读一行数据。
ser.readlines()：读多行数据。
in_waiting()：返回接收缓存中的字节数。
flush()：等待所有数据写出。
flushInput()：丢弃接收缓存中的所有数据。
flushOutput()：终止当前写操作，并丢弃发送缓存中的数据。

4. 驱动下载
- 使用驱动精灵工具；
- 推荐使用dirverIdentifier软件，会自动检测系统设备管理器上各种驱动问题，然后提供对应的驱动安装口；
5. 学习链接
- https://github.com/Oslomayor/PyQt5-SerialPort-Stable
- 几种串口工具
6. 问题记录
serial.serialutil.SerialException: WriteFile failed (PermissionError(13, ‘拒绝访问。’, None, 5))
从电源关闭设备；
