Independent modes

1.1

Single-channel, single conversion mode

1.1.1

Description

This is the simplest ADC mode. In this mode, the ADC performs the single conversion
(single sample) of a single channel x (refer to
conversion.
Note: This application note is not delivered with a firmware example of this mode.

1.1.2

Example of application

This mode can be used for the measurement of a voltage level to decide if the system can
be started or not. Measure the voltage level of the battery before starting the system: if the
battery has a low level, the "low battery" message appears. In this case, do not start the
system.
1.2

Multichannel (scan), single conversion mode

1.2.1 Description
This mode is used to convert some channels successively in independent mode. With the
ADC sequencer, you can use this ADC mode to configure any sequence of up to 16
channels successively with different sampling times and in different orders. You can for
example carry out the sequence shown in
ADC during the conversion process in order to reconfigure the next channel with a different
sampling time. This mode saves additional CPU load and heavy software development.
