PORT

PORT is use to generate current to the pin. For ‘1’ is given 5V(20mA) and ‘0’ is given 0V. Before using port, tris must be declared first. For example, when we want to use PORTB so we have to declared TRISB. 

PORTB=0b00000000;  // in binary symbol

PORTB=0x00;              // in hex symbol

RB0 to RB7 is given 0V (0mA).

------------------------------------------------------------ 

PORTB=0b11111111;     // in binary symbol

PORTB=0xFF;                 // in hex symbol

RB0 to RB7 is given 5V (20mA).

------------------------------------------------------------ 

PORTB=0b01101001;    // in binary symbol

PORTB=0x69;                 // in hex symbol

RB0, RB3, RB5, RB6 is given 5V (20mA).

RB1, RB2, RB4, RB7 is given 0V (0mA).

In MikroC, for time delay it has specialist. MikroC have already made a special library for time delay. It can be used easily and simple to calculate.

delay_ms(500);  // delay for 500ms or 0.5s

delay_us(500);  // delay for 500us or 0.0005s
