8 Using TMR2 for Auto-Conversion Trigger for the
ADCC Module
This example will present how to use the TMR2 peripheral to trigger the ADCC
to make conversions at a fixed frequency rate that can be adjusted by modifying the TMR2
period.
The application will blink the LED0 with a rate of Timer2 period (100 ms),
get the ADCC value and compare it with a desired threshold and, if it is higher, the
LED0 will stop blinking.
This example uses the PIC18F47Q10 Curiosity Nano board with a POT click,
both inserted into a Curiosity Nano adapter. For more details, visit the Hardware
Configuration section in the GitHub repository.
To achieve the functionality described by this use case, the following
actions will have to be performed:
System clock initialization
ADCC initialization and
reading
Port initialization
Timer2 initialization
Interrupts handling and
initialization
