一、依赖库
import subprocess
import serial
from serial.tools import list_ports
import logging
import time
二、代码
python
import subprocess
import serial
from serial.tools import list_ports
import logging
import time
def 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}')
# break
print("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 = 0
while 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. Performing operations...")
break
else:
print("Device not found. Switching modes and retrying...")
openAdb(com)
count += 1
if count >= 5:
print("Please check if the environment is OK")
break
except subprocess.CalledProcessError as e:
print("An error occurred while executing adb command:", e)
break
if __name__ == '__main__':
com = 'COM24'
# openAdb(com)
check_adb(com)
三、使用场景
需要外接继电器,通过串口命令打开车机调试模式
