The software flowchart for this lab is shown in Figure 4-6.
FIGURE 4-6:
The Initialize() configures the PIC16F690 as follows:
• Configure PORTC pins RC0, RC1, RC2 and RC3 and digital outputs
• Comparator 1
• CV
• Timer1 Configuration:
• Timer0
The Interrupt Service Routine, TMR0_ISR(), is shown in Figure 4-7.
Lab Development Board User’s Guide
- Enable Comparator 1.
- Make the Comparator 1 output available on the C1OUT pin configuring
- Route the CV
- Select pin C12IN0- as the inverting reference configuring TRISA1 as an input.
- Configure the C1OUT pin as an output.
- Configure CV
- Select the T1CKI pin as the Timer1 clock source making TRISA5 an input.
- Clear both Timer1 result registers TMR1H:TMR1L.
- Turn on Timer1.
- Select F
- Assign the prescaler to Timer0 and configure so that the TMR0 register
- Enable Timer0 interrupt-on-overflow
- Clear the Timer0 interrupt flag
- Preload TMR0 with 10 (this ensures that a Timer0 interrupt will occur before
- Enable Global Interrupts on the PIC16F690.
