import serial
from time import sleep
def recv(serial):
while True:
data = serial.read_all()
if data == '':
continue
else:
break
sleep(0.02)
return data
if __name__ == '__main__':
serial = serial.Serial('COM5', 9600, timeout=0.5) #/dev/ttyUSB0
if serial.isOpen() :
print("open success")
else :
print("open failed")
while True:
data =recv(serial)
if data != b'' :
print("receive : ",data)
serial.write(data) #数据写回
3.结果
