数据以 16 进制发送到树莓派

#实例化串口
import serial;
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout = 0.5);

#需要发送的数据
strnum = 7e 00 08 01 00 02 01 ab cd
.....
#这里该如何将 strnum 转换为 16 进制
strSerial = strnum
ser.write(strSerial)

strnum

serial

找到方法了:

import binascii

def order_list():
a = 'aa0902630000bb'
a_list = []
for i in a.split():
a_list.append(binascii.a2b_hex(i))
return a_list

ser = serial.Serial('/dev/ttyUSB0', 9600)
ser.writelines(order_list())
