In the flow of the main processing of the program, first set up the output pin of the LED
and the input pin to be used for the A/D converter. The settings of the pins are explained
in the previous chapter. Then, make the settings related to the A/D converter. The
settings to be made are about the same as the previous chapter. The only difference is
that the channel of the A/D converter to be used is set to "1" (Channel 0 is used in the
previous chapter). The operation mode of the A/D converter is set to the continuous
conversion mode that is also used in the previous chapter. The operation of the A/D
converter is as follows accordingly.
A/D converter is activated (A/D conversion starts) ⇒ A/D conversion ends ⇒ A/D
conversion starts - - -
When the A/D conversion ends, an interrupt of the A/D converter is generated, and an
interrupt routine is called. In the interrupt routine, the interrupt factor is cleared, the A/D
value is obtained, and the LEDs are lighted according to the obtained A/D value. The
LED lighting processing is as shown in Table 8.4 LED lighting processing.
