Checksum (+CRC-8) #2

Closed EmlJnke closed 5 years ago

EmlJnke commented 5 years ago

Hi, I just wanted to know if You know more about the checksum stuff! I read the rtl_433 code for like some hours but I'm not really into c so I now know that there are 2 checks in the signal but I really don't know how to use them. Could you give me a clue how these work in the signal? (like how the addition checksum works, what to add to each other :D)

Thanks, Emil

Ok, I figured out how the addition checksum works. The Decoding and the checksum is done separately in a python file in my fork of this project. (I will commit that soon if anyone's interested ^^)
