The other template code in this tutorial can be left in or commented out. It is probably
better to comment it out at this time since these definitions will get compiled and take
up memory space. Make sure to comment out all the sample arrays, since they use the
macros which can be commented out. Also, as the code grows, it may be difficult to
remember which code is used by the application and which was part of the original
template.
After the section labelled
END OF GLOBAL DEFINITIONS
type in this routine to
initialize Timer 1 as an interrupt timer using the internal clock (the bolded text is the
code that should be typed in):
EXAMPLE 3-4:
RESET_CLOCK CODE
This routine uses special function register names, such as
TMR1
and
T1CONbits.TCS
that are defined in the header file
p30F6014.h
. Refer to the data sheet for more
information on these control bits and registers for Timer 1.
Note:
When using the template, remember that when beginning to code the
application, only a few elements of the template may be needed. It may be
helpful to comment out those portions of code that are not being used so
that later, when similar elements are needed, they can be referred back to
as models.
