ser=serial.Serial(port='COM3',baudrate=9600,timeout=1) 1. 这里,我们打开了COM3端口,波特率设置为9600,超时时间为1秒。 4. 设置缓冲区大小 在调用serial.Serial()后,可以通过set_buffer_size()方法设置缓冲区大小。以下代码示例展示了如何设置输入和输出缓冲区的大小。 ser.set_buffer_size(rx_size=128,t...

from serial import Serial ser = Serial(port='COM1', baudrate=115200, timeout=1, writeTimeout=1) ser.set_buffer_size(rx_size = 12800, tx_size = 12800) 其中12800 是我选择的任意数字。您可以使接收 (rx) 和传输 (tx) 缓冲区与 2147483647 一样大(等于 2^31 - 1) 这将允许您扩展输入缓...
