FIGURE 3-11:
The Timing() delay routine is shown in Figure 3-12.
FIGURE 3-12:
Two variables are used delay_var1 and delay_var2. The delay_var2 is decre-
mented by 1 each time delay_var1 is decremented from 45571 to 0. These values
have been determined through trial and error using a test procedure detailed in the
“Timers: Timer0 Tutorial (Part 1)” (DS51682.pdf) included on the PICDEM™ Lab
Development Kit CD. This delay ties the up the processor for 1 second when using the
4 MHz internal oscillator.
The Initialize() configures the PORTC as follows:
• PORTC

- Set all bits in the PORTC register HIGH
- Configure all PORTC pins as digital outputs

Create two 8-bit variables:
• delay_var1 = 45571
• delay_var2 = 3
delay_var1 = 45571
delay_var2 - 1 = 0
delay_var1 - 1 = 0
