comment "Device Driver Configuration"
config DEV_NULL
bool "Enable /dev/null"
default y
config DEV_ZERO
bool "Enable /dev/zero"
default n
config LOOP
bool "Enable loop device"
default n
---help---
Supports the standard loop device that can be used to export a
file (or character device) as a block device. See losetup() and
loteardown() in include/nuttx/fs/fs.h.
config RAMDISK
bool "RAM disk support"
default n
---help---
Can be used to set up a block of memory or (read-only) FLASH as
a block driver that can be mounted as a files system. See
include/nuttx/ramdisk.h.
config CAN
bool "CAN support"
default n
---help---
This selection enables building of the "upper-half" CAN driver.
See include/nuttx/can.h for further CAN driver information.
if CAN
config CAN_EXTID
bool "CAN extended IDs"
default n
---help---
Enables support for the 29-bit extended ID. Default Standard 11-bit IDs.
config CAN_FIFOSIZE
int "CAN driver I/O buffer size"
default 8
---help---
The size of the circular buffer of CAN messages. Default: 8
config CAN_NPENDINGRTR
int "Number of pending RTRs"
default 4
---help---
The size of the list of pending RTR requests. Default: 4
config CAN_LOOPBACK
bool "CAN extended IDs"
default n
---help---
A CAN driver may or may not support a loopback mode for testing. If the
driver does support loopback mode, the setting will enable it. (If the
driver does not, this setting will have no effect).
endif
config PWM
bool "PWM support"
default n
---help---
This selection enables building of the "upper-half" PWM driver.
See include/nuttx/pwm.h for further PWM driver information.
if PWM
config PWM_PULSECOUNT
bool "PWM pulse count support"
default n
---help---
Some hardware will support generation of a fixed number of pulses. This
might be used, for example to support a stepper motor. If the hardware
will support a fixed pulse count, then this configuration should be set to
enable the capability.
endif
config I2C
bool "I2C support"
default n
---help---
This selection enables building of the "upper-half" I2C driver.
See include/nuttx/i2c.h for further I2C driver information.
if I2C
endif
config SPI
bool "SPI support"
default n
---help---
This selection enables building of the "upper-half" SPI driver.
See include/nuttx/spi.h for further SPI driver information.
if SPI
config SPI_OWNBUS
bool "SPI single device"
default y
---help---
Set if there is only one active device on the SPI bus. No locking or SPI
configuration will be performed. It is not necessary for clients to lock,
re-configure, etc..
config SPI_EXCHANGE
bool "SPI exchange"
default y
---help---
Driver supports a single exchange method (vs a recvblock() and sndblock ()methods).
config SPI_CMDDATA
bool "SPI CMD/DATA"
default y
---help---
Devices on the SPI bus require out-of-band support to distinguish command
transfers from data transfers. Such devices will often support either 9-bit
SPI (yech) or 8-bit SPI and a GPIO output that selects between command and data.
endif
config WATCHDOG
bool "Watchdog timer support"
default n
---help---
This selection enables building of the "upper-half" watchdog timer driver.
See include/nuttx/watchdog.h for further watchdog timer driver information.
if WATCHDOG
endif
menuconfig ANALOG
bool "Analog Device(ADC/DAC) support"
default n
---help---
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.
if ANALOG
source drivers/analog/Kconfig
endif
config BCH
bool "BCH support"
default n
---help---
Contains logic that may be used to convert a block driver into
a character driver. This is the complementary conversion as that
performed by loop.c. See include/nuttx/fs/fs.h for registration
information.
if BCH
source drivers/bch/Kconfig
endif
menuconfig INPUT
bool "Input device support"
default n
---help---
This directory holds implementations of input device drivers.
This includes such things as touchscreen and keypad drivers.
See include/nuttx/input/*.h for registration information.
if INPUT
source drivers/input/Kconfig
endif
menuconfig LCD
bool "LCD support"
default n
select NX_LCDDRIVER
---help---
Drivers for parallel and serial LCD and OLED type devices. These
drivers support interfaces as defined in include/nuttx/lcd/lcd.h
This selection is necessary to enable support for LCD drivers in
drivers/lcd as well as for board-specific LCD drivers in the configs/
subdirectories.
if LCD
source drivers/lcd/Kconfig
endif
menuconfig MMCSD
bool "MMC/SD support"
default n
---help---
Support for MMC/SD block drivers. MMC/SD block drivers based on
SPI and SDIO/MCI interfaces are supported. See include/nuttx/mmcsd.h
and include/nuttx/sdio.h for further information.
if MMCSD
source drivers/mmcsd/Kconfig
endif
menuconfig MTD
bool "Memory Technology Device (MTD) support"
default n
---help---
Memory Technology Device (MTD) drivers. Some simple drivers for
memory technologies like FLASH, EEPROM, NVRAM, etc. See
include/nuttx/mtd.h
(Note: This is a simple memory interface and should not be
confused with the "real" MTD developed at infradead.org. This
logic is unrelated; I just used the name MTD because I am not
aware of any other common way to refer to this class of devices).
if MTD
source drivers/mtd/Kconfig
endif
menuconfig NETDEVICES
bool "Network Device support"
default n
---help---
Network interface drivers. See also include/nuttx/net/net.h
if NETDEVICES

menuconfig PIPES
bool "FIFO and named pipe drivers"
default n
---help---
FIFO and named pipe drivers. Standard interfaces are declared
in include/unistd.h
if PIPES
source drivers/pipes/Kconfig
endif
config PM
bool "Power management (PM) driver interfaces"
default n
---help---
Power management (PM) driver interfaces. These interfaces are used
to manage power usage of a platform by monitoring driver activity
and by placing drivers into reduce power usage modes when the
drivers are not active.
menuconfig POWER
bool "Power management device support"
default n
---help---
Enable building of power-related devices (battery monitors, chargers, etc).
if POWER
source drivers/power/Kconfig
endif
menuconfig SENSORS
bool "Sensors support"
default n
---help---

source drivers/sensors/Kconfig
endif
menuconfig SERCOMM_CONSOLE
bool "Osmocom-bb serial console"
default n
---help---
Sercomm is the transport used by osmocom-bb that runs on top of serial.
See http://bb.osmocom.org/trac/wiki/nuttx-bb/run for detailed the usage
of nuttx with sercomm.
drivers/sercomm is only built if SERCOMM_CONSOLE in the NuttX
configuration file. If you attempt to build this driver without
osmocom-bb, you will get compilation errors because of header files
that are needed from the osmocom-bb.
if SERCOMM
source drivers/sercomm/Kconfig
endif
menuconfig SERIAL
bool "Serial support"
default y
---help---
Front-end character drivers for chip-specific UARTs. This provide
some TTY-like functionality and are commonly used (but not required for)
the NuttX system console. See also include/nuttx/serial/serial.h
if SERIAL
source drivers/serial/Kconfig
endif
menuconfig USBDEV
bool "USB device support"
