Hi,

can you translate for me this program for sdcc (from keil)

Regards

/ Variablen-Deklaration (sbit = Bit im "special function register") /
sbit LED1 = P1^0; / Bit 0 von Port P1 /
sbit Taste1 = P0^0; / Bit 0 von Port P0 /
/ Hauptprogramm /
void main(void)
{
while (1) / Endlosschleife /
{
LED1 = Taste1; / LED1 = 0, wenn Taste1 = 0 /
}
}

Hi,

note, Keil uses a different syntax to define SFR and sbits. Maybe also check chapter 6.1 "Porting code from or to other compilers".

#include <8051.h>

#define Taste1 P0_0 /* Bit 0 von Port P0: __sbit __at (0x80) P0_0 */
#define LED1   P1_0 /* Bit 0 von Port P1 */
/* Hauptprogramm */
void main(void)
{
    while (1)
    {
        LED1 = Taste1; /* LED1 = 0, wenn Taste1 = 0 */
    }
}

compiles to

      000062                        312 _main:
                                    321 ;   p00_to_p10.c:8: while (1)
      000062                        322 00102$:
                                    323 ;   p00_to_p10.c:10: LED1 = Taste1; /* LED1 = 0, wenn Taste1 = 0 */
      000062 A2 80            [12]  324     mov c,_P0_0
      000064 92 90            [24]  325     mov _P1_0,c
