How to define Rb0 to Rb6 = hex (x%10); // no Rb7 pin

Question

Using MikroC Pro for PIC16f73 to multiplexing 7 segment the written program is:

PORTB = Hex (x%10);

There PORTB means RB0 to RB7 total 8 pins are includes, but I want to use only 7 pins for 7 segments RB0 to RB6, and the pin RB7 as other O/P just 0 or 1.

As like Rb0 to Rb6 = hex (x%10) and Rb7_bit = 0 or 1

so how to define the line Rb0 to Rb6 = hex (x%10);

Answer 1

Try this:

uint8_t   Pin_Value;

Pin_Value = Hex (x%10);
Pin_Value |= 0x80;       //set bit RB7
Pin_Value &= 0x7F;       //clear bit RB7
PORTB     = Pin_Value;
