5.7.2
5.7.2.1
This function configures the LCD peripheral for this board and this glass. Type B
waveforms are used to allow the LCD peripheral to be used for the real time clock
function. The Timer1 oscillator is configured as the LCD clock source.
FIGURE 5-7:
5.7.2.2
This function accepts a BCD_TYPE variable and maps each digit to the correct
segments. Mapping the segments is done in two stages. First, the digit is converted to
the correct 7-segment mapping. Then, the 7-segment mapping is converted to the
actual glass segments with a long series of “if-else” statements. This function will need
extensive work in the “if-else” statements for applications driving different glass.
FIGURE 5-8:
5.7.2.3
These two functions simply turn the LCD peripheral off. The Timer1 oscillator is left
running. One use for these functions is to implement display blinking.
