11.0. A/D Converter
An A/D converter is used for the purpose of converting an analog signal into the appropriate digital value. A/D converter is linear, which means
that the converted number is linearly dependent on the input voltage value.
The A/D converter built into the microcontroller provided with the EasyPIC6 development system converts an analog voltage value into a
10-bit number. Voltages varying from 0V to 5V DC may be supplied through the A/D test inputs. Jumper J15 is used for selecting some of the
through the potentiometer or the microcontroller pin. The value of the input analog voltage can be changed linearly using potentiometer P1.

In order to enable the microcontroller to accurately perform A/D conversion, it is necessary to turn off LED diodes and
pull-up/pull-down resistors on port pins used by the A/D converter.
