RE: [Sdcc-user] Setting Specific Address for a code segment

[Rod B. <rod_boyce@DMCWave.com>]

A bit more information would be useful here.  I'll assume you are trying to
get your interrupt to be called.  I struck this problem when I was playing
with SDCC as well the answer is in the manual (the PDF at least) but I give
you the short form.  When compiling multi file programs you must link the
file with main in it first and inside the file with main in it you must put
a prototype of all interrupt functions you are using this then files out the
interrupt jump table automatically.  By an interesting coincidence all
unused interrupts get a RETI instruction put in their place very useful.

Subject: [Sdcc-user] Setting Specific Address for a code segment


I have two C files one contains the main file the other contains the
Interrupt Service Routines.
 
I am trying to use some inline Assembly, however I'm having problems setting
up the 8051 Autovectoring Jump table.
 
Any help would be greatly appreciated!
 
Thanks in advanced,
