Hello

Smile

I want to know if I can use the two pins D- and D+ of a pic 18f4550 as logic pins ?
I try but they didn't work :/
If someone can helpe me I will be so thankful.

Code:

#include <18f4550.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,PUT
#USE DELAY(CLOCK=20MHZ, CRYSTAL)

#byte portc = 0xF82
#byte trisc = 0xF94

void main(void){
portc=0b00000000;
trisc=0b11111111;

while(1){
output_high(pin_c4);
delay_ms(1000);
output_low(pin_c4);
delay_ms(1000);

output_high(pin_c5);
delay_ms(1000);
output_low(pin_c5);
delay_ms(1000);
}
}
