This commit does two things: 1. First, it reorganizes the driver Kconfig files so that each is self contained. Before, a part of the driver configuration was in drivers/Kconfig and the rest was in in drivers/xyz/Konfig. Now, all of the driver configuration is consolitated in the latter. 2. Second, this commit correct numerous serious errors introduced in a previous reorganization of the driver Kconfig files. This was first noted by Nicholas Chin in PR270 for the case of the drivers/i2c/Kconfig but some examination indicates that the error was introduced into several other Kconfig files as well. The nature of the introduced error was basically this: - Nothing must intervene between the menuconfig selection and the following conditional configuration otpions. - A previous PR erroneously introduced unconditional options between the menuconfig and the following confditional logic, thus corrupting the driver menus. This error was easy to make because the driver Kconfig files were not well modularized. Making them fully self-contained should eliminate this kind of error in the future.

This directory holds implementations of analog device drivers.

This includes drivers for Analog to Digital Conversion (ADC) as
|
|
well as drivers for Digital to Analog Conversion (DAC).

See include/nuttx/analog/*.h for registration information.

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 is a ring buffer, the actual number of bytes that can be

retained in buffer is (ADC_FIFOSIZE - 1).
