USING THE RTCC DRIVER
5.7.3
FIGURE 5-10:
There are many segments present on the F1 Evaluation Platform LCD. To access these
segments, simply set the supplied #defines to 1 or 0.
FIGURE 5-11:
The RTC driver simply keeps track of seconds. The power-up initial value is ‘0’,
however a function (rtcc_set) is provided to change that value. To keep the seconds
up-to-date, the function, rtcc_handler, must be called more frequently than the
defined value of CLOCKS_PER_SECOND. There are two options for the RTCC driver.
The first option is to use the Timer1 counter to provide a 1 Hz interrupt
(CLOCKS_PER_SECOND = 1). The second option is to use the LCD write-allowed
interrupt flag to provide a 128 Hz event (CLOCKS_PER_SECOND = 128). The two
choices are selected by defining use_lcdif or undefining use_lcdif.
