Pull up RB1 on pic18f2520

[kle0ps]

Hello guys.
Does anyone know how to pull up only RB1 on PIC18F2520?
I use C18 compiler
Thank you

Do you want to connect a pullup resistor to RB1? Just connect one end of 10K resistor to 5v and the other end to RB1.

Hello mate
I know that, but i want to connect my pic18f2520 with arduino. i want to sent HIGH (3-5V) from RB1 to arduino only when I want, not continuously

Then write the code to make pin RB1 high or low according to your need.

Then write the code to make pin RB1 high or low according to your need.

I set PORTB as ouputs and i set PORTBbits.RB0==1; (HIGH) but when i measure the voltage on RB0 was zero

- - - Updated - - -

Finally i fix it. I change PORTBbits.RB0==1 to PORTA=0b00000001;
Thank you mate!

When you want to write to a bit or a register, you use only = , not ==.

Like you used

PORTBbits.RB0 = 1;

If you want to check/compare, then you use == instead of =.

if (PORTBbits.RB0 ==1){

}
if (PORTD == 255){

}

Hope this helps.
Tahmid.
