以编程方式与OS X或Linux中的串行端口通信

pip install pyserial

import serial
import time

# 设置串行端口的参数
serial_port = "/dev/ttyUSB0"
baud_rate = 9600
timeout = 1

# 打开串行端口
ser = serial.Serial(serial_port, baud_rate, timeout=timeout)

# 发送数据到串行端口
data_to_send = "Hello, World!"
ser.write(data_to_send.encode())

# 读取串行端口的数据
received_data = ser.readline()

# 关闭串行端口
ser.close()

print("发送的数据: ", data_to_send)
print("接收的数据: ", received_data.decode())

pip install osx-serial-port

import serial
import time

# 设置串行端口的参数
serial_port = "/dev/tty.usbserial"
baud_rate = 9600
timeout = 1

# 打开串行端口
ser = serial.Serial(serial_port, baud_rate, timeout=timeout)

# 发送数据到串行端口
data_to_send = "Hello, World!"
ser.write(data_to_send.encode())

# 读取串行端口的数据
received_data = ser.readline()

# 关闭串行端口
ser.close()

print("发送的数据: ", data_to_send)
print("接收的数据: ", received_data.decode())
