文件中定义了SerialException、SerialTimeoutException等I/O、 timeout等错误,都是继承过来的,暂时还没了解那么深入 此外定义了一些byte转换的函数,serial转发中,估计实际转发是byte数据格式,所以会有对应的函数来支持,在后面的write和read中可以看到这方面的使用 附加了一些read操作,但基本不常用 ps:该模块中会用到一...
(3)timeout: 读取超时时间,单位为秒。如果设置为None,则read()操作会一直等待数据到达;如果设置为0,read()操作会立即返回;如果设置为一个正数,read()操作会等待指定秒数,如果在这个时间内没有数据到达,则返回空。 (4)bytesize: 数据位的位数,默认为8。 (5)parity: 校验位,可以是serial.PARITY_NONE(无校验...
inter_byte_timeout (float)—字符间超时,默认为None。 打开串口2 根据“打开串口1”我们可以打开一个串口,ser = serial.Serial(“COM3”)语句我们就打开了com3其他使用了默认配置。实际使用中我们也可以在程序里面配置串口参数 import serial ser = serial.Serial() ser.port = "COM3" ser.baudrate = 9600 ...

Changed default inter-byte timeout to 0.5ms based on recommendations from users. Updated documentation to mention that the AsciiSerial and BinarySerial classes are compatible with Python’s “with” statement. Split up the monolithic source files into one file per class, for easier maintenance and...
