config DEV_NULL
|

bool "Enable /dev/null"

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 RAMLOG
|
|
bool "RAM log message support"
|
|
default n
|
|
---help---
|
|
This is a driver that was intended to support debugging output,
|
|
aka syslogging, when the normal serial output is not available.
|
|
For example, if you are using a telnet or USB serial console,
|
|
the debug output will get lost.
|
|
|
|
This driver is similar to a pipe in that it saves the debugging
|
|
output in a FIFO in RAM. It differs from a pipe in numerous
|
|
details as needed to support logging.
|
|
|
|
config CAN
|
|
bool "CAN support"

default n

config 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 CONFIG_CAN_NPENDINGRTR
|
|
int "Number of pending RTRs"
|
|
default 4
|
|
---help---
|
|
The size of the list of pending RTR requests. Default: 4
|
|
|
|
config 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).

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.

|
|
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.

confused with the "real" MTD developed at infradead.org. This
