Hello,
I am trying to use SDCC to compile a simple blink led program, but I get stuck
with the #define LED something
I tried to put PORTA_bits.RA4 (instead of something). And in my main header
file I defined :
typedef union {
struct {
unsigned char RA0:1;
unsigned char RA1:1;
unsigned char RA2:1;
unsigned char RA3:1;
unsigned char RA4:1;
unsigned char RA5:1;
unsigned char RA6:1;
unsigned char RA7:1;
};
} __PORTA_bits_t;
extern volatile __PORTA_bits_t __at(PORTA_ADDR) PORTA_bits;
But I get this error :
missing definition for symbol "_PORTA_bits", required by "led.o"
So I edited my main c file (main.c) and added :
volatile __PORTA_bits_t __at(PORTA_ADDR) PORTA_bits;
Now I get this error :
multiple sections using address 0x5
I really don't know how to do this #define so I can simply test and set a pin.
I looked and the pic16f88.h and pic16f88.c in the share/sdcc/ folder and
changed thing but still no improvement. I also found a pic16f88.lib which I
think should be modify (re-compiled) to add the PORTA_bits structure, but I
don't know how to do it.
Thanks for your help.
PS: I am not on the mailing list so please reply to that adress.
