[Icc-avr] CheckSum

[Albert vanVeen]

It would indeed be a good idea to add a checksum to comms functions!
Depends what you want: plain CS, CRC, Fletcher?
We've used FCS in the companies I've worked the last 20 or so years,
seems to be accepted as "the best" value for 16 bits.

Subject: [Icc-avr] CheckSum



Hi,

 

I am sure I have asked this before but (if i have sorry for the repeat
question), does anybody have a simple checksum routine for an array of
bytes, they would not mind posting?

 

I need one for a maximum of 250 bytes I am sending through the serial
port to a PC (I could break this up into smaller chunks if needed ) at
the moment i am not using one, but I think it would be best to add one. 

 

I have found a few on AVR freaks, just wondered what everyone here uses.

 

Best Regards,

 

Andy
