FIGURE 5-3:
Following the Get_Inputs(), the 10-bit ADC result is now in the ADRESH:ADRESL
registers. The Decide() assigns the ADC result value, shifted four bit positions to the
right, to the LED_Output variable.
Finally, the Do_Outputs() assigns the contents of LED_Output to the PORTC
register that will light the LEDs connected to RC0, RC1, RC2 and RC3 accordingly.
5.2.3.3
Using the Project Wizard, create a new project called ADC_Lab1.mcp. Once com-
pleted, open the ADC_Lab1.c source file in MPLAB and make the following changes:
1. Copy/paste the code in Example 5-1 into the top of the main firmware source file
EXAMPLE 5-1:
2. Copy/paste the code in Example 5-2 into the top of the main firmware source file
