Hello,

I am using mikroC for programming PIC uC. I would like to set internal pullup at pins of PORTB, but I have a problem with instruction OPTION_REG.F7 = 0;.

Returned error: Undeclared identifier 'OPTION_REG' in expression

How can I solve this problem?
 

PORTB pullups are enabled by bit RBPU in INTCON2 register. I can't imagine that it's renamed to "OPTION_REG" in mkroC. Where did you get the idea?

on the Internet... I think that this instruction is valid, becous it works added manualy in some example projects like PortExpander
