NOTE: You cannot have both the CDC/ACM and the MSC class drivers enabled
simultaneously in the way described here. If you want to use both, then
you will need to consider a USB "composite" devices that support supports
both interfaces. There are no instructures here for setting up the USB
composite device, but there are other examples in the NuttX board support
directories that can be used for reference.

HSMCI
=====
Enabling HSMCI support. The SAM3U-KE provides a an SD memory card slot.
Support for the SD slot can be enabled with the following settings:
System Type->ATSAM3/4 Peripheral Support
CONFIG_SAM34_HSMCI=y : Enable HSMCI support
CONFIG_SAM34_DMAC0=y : DMAC support is needed by HSMCI
System Type
CONFIG_SAM34_GPIO_IRQ=y : PIO interrupts needed
CONFIG_SAM34_GPIOA_IRQ=y : Card detect pin is on PIOA
Device Drivers -> MMC/SD Driver Support
CONFIG_MMCSD=y : Enable MMC/SD support
CONFIG_MMSCD_NSLOTS=1 : One slot per driver instance
CONFIG_MMCSD_HAVECARDDETECT=y : Supports card-detect PIOs
CONFIG_MMCSD_SDIO=y : SDIO-based MMC/SD support
CONFIG_SDIO_DMA=y : Use SDIO DMA
CONFIG_SDIO_BLOCKSETUP=y : Needs to know block sizes
Library Routines
CONFIG_SCHED_WORKQUEUE=y : Driver needs work queue support
Application Configuration -> NSH Library
CONFIG_NSH_ARCHINIT=y : NSH board-initialization
Touchscreen
===========
The NSH configuration can be used to verify the ADS7843E touchscreen on
the SAM4E-EK LCD. With these modifications, you can include the touchscreen
test program at apps/examples/touchscreen as an NSH built-in application.
You can enable the touchscreen and test by modifying the default
configuration in the following ways:
Device Drivers
CONFIG_SPI=y : Enable SPI support
CONFIG_SPI_EXCHANGE=y : The exchange() method is supported
CONFIG_SPI_OWNBUS=y : Smaller code if this is the only SPI device
CONFIG_INPUT=y : Enable support for input devices
CONFIG_INPUT_ADS7843E=y : Enable support for the XPT2046
CONFIG_ADS7843E_SPIDEV=2 : Use SPI CS 2 for communication
CONFIG_ADS7843E_SPIMODE=0 : Use SPI mode 0
CONFIG_ADS7843E_FREQUENCY=1000000 : SPI BAUD 1MHz
CONFIG_ADS7843E_SWAPXY=y : If landscape orientation
CONFIG_ADS7843E_THRESHX=51 : These will probably need to be tuned
CONFIG_ADS7843E_THRESHY=39
System Type -> Peripherals:
CONFIG_SAM34_SPI0=y : Enable support for SPI
System Type:
CONFIG_GPIO_IRQ=y : GPIO interrupt support
CONFIG_GPIOA_IRQ=y : Enable GPIO interrupts from port A
RTOS Features:
CONFIG_DISABLE_SIGNALS=n : Signals are required
Library Support:
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
Application Configuration:
CONFIG_EXAMPLES_TOUCHSCREEN=y : Enable the touchscreen built-in test
Defaults should be okay for related touchscreen settings. Touchscreen
debug output on UART0 can be enabled with:
Build Setup:
CONFIG_DEBUG=y : Enable debug features
CONFIG_DEBUG_VERBOSE=y : Enable verbose debug output
CONFIG_DEBUG_INPUT=y : Enable debug output from input devices
