pwm.c
Provides the "upper half" of a pulse width modulation (PWM) driver.
The "lower half" of the PWM driver is provided by device-specific
logic. See include/nuttx/pwm.h for usage information.
ramdisk.c
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.

ramlog.c
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.

drivers/sercomm README
======================
If CONFIG_SERCOMM_CONSOLE is defined in the NuttX configuration file, NuttX
will attempt to use sercomm (HDLC protocol) to communicate with the
host system. 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.
The drivers/sercomm build that you have the osmocom-bb project directory
at same level as the nuttx project:
|- nuttx
|- apps
`- osmocom-bb
If you attempt to build this driver without osmocom-bb, you will get
compilation errors because ofheader files that are needed from the
osmocom-bb directory.
