convert CRC value to bytes
I use python2.7 in windows. I want to calculate the crc value of an array of data to send it via serial port. The crc value calculated is 794(int). I have to convert it to bytes and attach it to the data to send.
I have tried:
import struct
struct.pack("<H", 794)
and bytes(794)
But the value got are 794.
How to convert int 794 to bytes in python 2.7?
