Hi,
Can anybody explain me how to implement a CRC in my project?
Basically I need to Tx a string, and then I need to Rx it.
I tried without a CRC and is not working.
Now, please do not give me a lot of theory, how it suppose to work.
If anybody is willing to help me, then give me an example, please.
(I learn better from analising a working example, rather than reading the theory).
Lets say I have this string to send:
Preamble: 0x55
Data: 0xF10010650101108E42E9000800C4000000
End: 0xAA
Please give me an example of how to do a CRC on this string on the Tx side, and then how to manipulate it after I Rx it.
Preamble and End will always be the same, of course.
Data will always be different (same length).
Thank you.

Hi,
Before you implement the CRC procedure, maybe you should try to make your Tx-Rx connection to work; then add the CRC result to the data you‘d like to send.
About the CRC calculation itself, you can find what you’re looking for on this site : http://www.lammertbies.nl/comm/info/crc ... ation.html
