I run sdcc on Mac Os X and had some problems to compile the pic16
library. I use the snapshot of 23 / 12 /2004.
You can do:
./configure --prefix=/home/mik/tools/sdcc
make
make install
for the normal installation. Then, may 'cp' command does not understand
the '-u' flag. You can do:
cd sdcc/device/lib/pic16 ///in the source dir
./configure
make
mikmac:~/Desktop/sdcc/device/lib/pic16 mik$ cp bin/*
~/programmation/sdcc/share/sdcc/lib/pic16/
And it must work with that.
You can try with the following code (test.c), that blink a LED (port E,
bit 1) at nearly 1 Hz.
/* compile with:
sdcc -mpic16 -p18f452 test.c
*/
/* initializes stack at RAM address 0x5ff */
#pragma stack 0x5ff 64
#include <pic18fregs.h>
void timerIT() interrupt 1 _naked
{
static unsigned char t=0;
INTCONbits.T0IF = 0;
if(t++ == 0x98) //un switch tous les 0x98.
{
LATE ^= 0x1; /*switch LED 1 */
t = 0;
}
_asm
RETFIE
_endasm;
}
void init()
{
/* configuration LED */
LATE = 0;
TRISE= 0xF8;
/*timer config: 8bit, prescaler: 256
T0CON = 0xC7;
/* use interrupt */
INTCONbits.T0IE = 1;
/*activation des ITS*/
INTCONbits.GIE = 1;
INTCONbits.PEIE = 1;
}
void main()
{
init();
while(1);
}
