bonsoir,
d'apres vous ce code est-il fonctionnel:

#include 30F4011.h

void main() {

  ADPCFG = 0xFFFF;
  LATB = 0;
  TRISB = 1;
  LATC = 0;
  TRISC = 0;
  while(1) {
    if (LATB1)  LATC1=1;
    if (LATB2)  LATC1=1;
    if (LATB3)  LATC1=1;
    if (LATB4)  LATC1=1;
  }
}

merci

PS: il s'ajit de dspic

du meme genre mais qui servirait cette fois à commander un moteur en PWM à partir de B1:

#include "30f4011.h"

/* Configuration Bit Settings */
_FOSCSEL(FRC_PLL)
_FOSC(CSW_FSCM_OFF & FRC_HI_RANGE & OSC2_CLKO)
_FPOR(PWRT_128)
_FGS(CODE_PROT_OFF)
_FBS(BSS_NO_FLASH)


void init_PWM()
{
    /* ~~~~~~~~~~~~~~~~~~~~~~ PWM1 Configuration ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ */    
    /* PWM1 I/O Control Register register */
    IOCON1bits.PENH      = 1;   /* PWM1H is controlled by PWM module */
    IOCON1bits.PENL      = 1;   /* PWM1L is controlled by PWM module */
    IOCON1bits.PMOD      = 0;   /* Select Complementary Output PWM mode */

    /* Load PDC1 register with initial Duty Cycle value */
    PDC1 = 640;                 /* Duty Cycle = PDC2*1.05nsec = 672nsec */

    /* Load PDTR1 and ALTDTR2 register with preset dead time value */
    DTR1    = 64;               /* Deadtime setting */
                                /* Deadtime = DTR1*1.05 = 67.2nsec */
    ALTDTR1 = 64;               /* Deadtime setting */
                                /* Deadtime = ALTDTR1*1.05 = 67.2nsec */
    /* PHASE1 register */
    PHASE1 = 0;                 /* No phase shift */


 
    /* Configure PTPER register to produce 400kHz PWM frequency */
    PTPER = 2380;               /* PWM Period @30 MIPS, 2.5usec == 400kHz */
                                /* Period = PTPER*1.05nsec = 2.499usec

    /* PWM Time Base Control Register */
    PTCONbits.PTEN       = 1;   /* Enable the PWM Module */
 


}


int main()
{
    init_PWM();
    ADPCFG = 0xFFFF;
    LATB = 0;
    TRISB = 1;
    while(1)
    {
      if (LATB1)  IOCON1bits=1;

}
