yeah
its all sorted now. Thanks.
The
only thing I am having trouble with at the moment is, I need to output the HEX
to a comport, and I am using ther ASyncPro comp. from Turbopower, but, it only
seems to output strings.
Anyone
know how I can output the hex data via the Asyncpro comps?
Thanks, Jeremy
06 =
06
+07 = 0d
+01 = 0e
+73 = 81
+01 = 82
+00 = 82
and the other thing with keep the
base byte means that at the end just make a (mysum and $ff to keep the first 8
bit).

Subject: [DUG] Pulling my hair
out
I am pulling my hair out here at
the moment.
I have this line of data
:-
0df20a0a02450231384301000a
Its a hex data. Now the last 0A is
the checksum.
The document I have says that the
checksum is made up of the SUM of BYTES for these values
:-
0a 0a 02 45 02 31 38 43 01
00
and this line of data has a HEX
checksum of 82 (thats 82 in HEX)
But I am stuffed if I can work it
out. I thought I had it figured out, but NO !
Can someone enlighten me how to
come to these values? I am SURE I am meant to know this, but its sure as hell
not coming to me.
