After that, permit interruptions of A/D converter. This is the end of the operation
settings of the A/D converter. Start the A/D conversion. In this program, the operation
mode of the A/D converter is set to the continuous conversion mode. 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 - - -
The operation repeats as shown above. 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, which is the volume size. The correspondence
between the volume size and the number of LEDs lighted is as shown in Table 7.3 LED
lighting according to volume .
*The sampling time includes the time for loading the A/D input voltage after
*The comparing time is the time to perform comparison operations of the sampled A/D voltage
the A/D conversion starts.
and the standard voltage of the A/D converter and to convert it to a digital value.
