Hi,
I'm an old SDCC fan and now I'm working on a project that uses the
pic18f66f15. I followed the steps to include support for it, and it
seems that everything worked fine but the pic18f66j15.h file doesn't
include the __CONFIG directives, so I chequed the p18f66j15.inc and it
says :
;==========================================================================
;
; IMPORTANT: For the PIC18 devices, the __CONFIG directive has been
; superseded by the CONFIG directive. The following settings
; are available for this device.
;
; Background Debugger Enable bit:
; DEBUG = ON Background debugger enabled; RB6 and RB7 are
dedicated to In-Circuit Debug
; DEBUG = OFF Background debugger disabled; RB6 and RB7
configured as general purpose I/O pins
;
; Extended Instruction Set Enable bit:
; XINST = OFF Instruction set extension and Indexed
Addressing mode disabled (Legacy mode)
...
...
I've tried to use the CONFIG directive without success because I think
it's an ASM directive. I've tried to manually set the config words but
they don't appear in the hex file, an example program is:
#include <pic18f66j15.h>
#include <delay.h>
#include "gato.h" // pin name macros
#pragma stack 0x200 0x100
// Set the __CONFIG words:
__code char __at 0x300000 _conf1 = 0xA7; // 101000001 01011 1110
wtdg - debug off - xinstr off
__code char __at 0x300001 _conf2 = 0x00; // no code protection
__code char __at 0x300002 _conf3 = 0x06; // EC - IESO = off - FCMEM =
off
__code char __at 0x300003 _conf4 = 0x0D; // wtdg 1:8192
__code char __at 0x300004 _conf5 = 0x30; // microcontroller mode
__code char __at 0x300005 _conf6 = 0x00; // microcontroller mode

As you can see in the last 3 lines, config info is always 0xFF and is
not located after 0x300000. If I overwrite the config info in the
programmer, I can make code run.
¿ Any advice ?
Thanks in advance
