Select to enable support for analog input device support. This includes
|
|
not only Analog-to-Digital Converters (ADC) but also amplifiers and
|
|
analog multiplexers.
|
|
|
|
This selection enables:
|
|
|
|
- The upper half, device-independent ADC character driver, and
|
|
- Selection of common lower half ADC drivers.
|
|
|
|
MCU-specific, lower half drivers may be selected independently of
|
|
CONFIG_ADC. However, if CONFIG_ADC is selected, then it is assume
|
|
that lower half ADC drivers will be used only with the common ADC
|
|
upper half driver.

This variable defines the size of the ADC ring buffer that is used
|
|
to queue received ADC data until they can be retrieved by the
|
|
application by reading from the ADC character device. NOTE: Since
|
|
this is a ring buffer, the actual number of bytes that can be

retained in buffer is (ADC_FIFOSIZE - 1).
