Checksum must be formed and added to each command. The checksum is the two’s complement. The checksum itself is in BYTE format and thus it may rotate over the max value upon calculation.
Yep, that's really about all I know
So, for the following ASCII string example:
the manual tells me that the 2s complement is 0x2E.
So I know how to do a 2s complement of numbers, and I can think of several ways to do it to a string (or, at least, representations of that string), but does anyone out there know the "right" way to do this before I try to brute force it?
