But incase of many industrial application that command fails to generate exact delays. Because Delay command is only the repetition of the NOP commands. So to avoid this the proper way to generate a delay is to use timer as counter. PIC18F452 and PIC18F4620 has 4 timers and timer 0 in both is 16 bit. So we use this. Code in video is as: MikroC version 5.6.1 void main() { PORTB.F0 = 0; TRISB.F0 = 0; PORTB.F0 = 0; T0CON = 0x07; /// 1:256 while(1) { PORTB.F0 = 1; /////////// Delay of 500ms using timer starts T0CON.TMR0ON = 1; /// Timer 0 enabled TMR0H = 0xD9; /// FFFF FF = H FF = L TMR0L = 0xDA; while( INTCON.TMR0IF == 0 ); T0CON.TMR0ON = 0; INTCON.TMR0IF= 0; /// cleared the register /////////// Delay of 500ms using timer ends PORTB.F0 = 0; /////////// Delay of 500ms using timer starts T0CON.TMR0ON = 1; /// Timer 0 enabled TMR0H = 0xD9; /// FFFF FF = H FF = L TMR0L = 0xDA; while( INTCON.TMR0IF == 0 ); T0CON.TMR0ON = 0; INTCON.TMR0IF= 0; /// cleared the register /////////// Delay of 500ms using timer ends } }
