外接串口板，通过串口打开adb模式

一、依赖库

import subprocess
import serial
from serial.tools import list_ports
import logging
import time

二、代码

import subprocessimport serial
from serial.tools import list_ports
import logging
import timedef openAdb(com):# com = []# for i in list_ports.comports():#     if 'USB Serial' in i.description:#         print(i.description)#         com = i.name#         print(com)#         logging.debug(f'serial port:{com}')#         breakprint("try to open adb")ser = serial.Serial(com, 115200, timeout=0.1)if ser.is_open:ser.write(b"\n")time.sleep(1)ser.write(b"root\n")ser.write(b"\n")time.sleep(1)ser.write(b"Visteon@JMC23651\n")time.sleep(1)ser.write(b"dtach -a /tmp/glconsole\n")ser.write(b"su\n")ser.write(b"Vist@jmc789\n")time.sleep(1)ser.write(b"start setmode_device\n")time.sleep(1)ser.close()def check_adb(com):count = 0while True:try:subprocess.run(["adb", "kill-server"], check=True)subprocess.run(["adb", "start-server"], check=True)output = subprocess.check_output("adb devices", shell=True).decode('utf-8')# print("Output of adb devices:", output.strip())devices = []lines = output.strip().split('\n')for line in lines[1:]:if '\tdevice' in line:device_info = line.split('\t')[0]devices.append(device_info)print(devices)if devices is not None and len(devices) > 0:print("Device found.
