Hi
I found a code to translate a ASCII string to PDU string.
You can download it from: **broken link removed**
It´s made for PC, and I had modified it to use on a PIC 18F242, because expensive memory use...
Well, I had compiled my code on CCS 3.322, and ist not working very well.....
Example: ascii string ===> buffer[]="hellohello" from
https://www.dreamfabric.com/sms/hello.html
in PDU must be: E8 32 9B FD 46 97 D9 EC 37
but the result in my code is: 6F 4A 4B 4C 4D 4E 4F 50 51
I think than problem is how CCS drives the pointer and array, can you help me??
Thank you...
my code is:
MAIN.C
PDUCONV.C

* Functions for converting between an ISO-8859-1 ASCII string and a

*
* This code is released to the public domain in 2003 by Mats Engstrom,

#define NPC7 63
#define NPC8 '?'
****************************************************************************
This lookup table converts from ISO-8859-1 8-bit ASCII to the
7 bit "default alphabet" as defined in ETSI GSM 03.38
ISO-characters that don't have any correspondning character in the
7-bit alphabet is replaced with the NPC7-character. If there's
a close match between the ISO-char and a 7-bit character (for example
the letter i with a circumflex and the plain i-character) a substitution
is done. These "close-matches" are marked in the lookup table by
having its value negated.
There are some character (for example the curly brace "}") that must
be converted into a 2 byte 7-bit sequence. These characters are
marked in the table by having 256 added to its value.
