User and Wake-Up keys
=====================
All pulled high and will be sensed low when depressed.
SW2 PC11 Needs J42 closed
SW3 PC12 Needs J43 closed
SW4 PA0 Needs J44 closed
LEDs
====
There are four LEDs on the ViewTool STM32F103/F107 board that can be controlled
by software: LED1 through LED4. All pulled high and can be illuminated by
driving the output to low
LED1 PA6
LED2 PA7
LED3 PB12
LED4 PB13
These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
defined. In that case, the usage by the board port is defined in
include/board.h and src/stm32_leds.c. The LEDs are used to encode OS-related
events as follows:
SYMBOL Meaning LED state
LED1 LED2 LED3 LED4
----------------- ----------------------- ---- ---- ---- ----
LED_STARTED NuttX has been started ON OFF OFF OFF
LED_HEAPALLOCATE Heap has been allocated OFF ON OFF OFF
LED_IRQSENABLED Interrupts enabled ON ON OFF OFF
LED_STACKCREATED Idle stack created OFF OFF ON OFF
LED_INIRQ In an interrupt N/C N/C N/C Soft glow
LED_SIGNAL In a signal handler N/C N/C N/C Soft glow
LED_ASSERTION An assertion failed N/C N/C N/C Soft glow
LED_PANIC The system has crashed N/C N/C N/C 2Hz Flashing
LED_IDLE MCU is is sleep mode Not used
After booting, LED1-3 are not longer used by the system and can be used for
other purposes by the application (Of course, all LEDs are available to the
application if CONFIG_ARCH_LEDS is not defined.
Serial Console
==============
Console Configuration
---------------------
The NuttX console is configured by default on USART1 at 115200 BAUD 8N1
(8-bits, not parity, one stop bit). These setting can, of course, easily
be changed by reconfiguring NuttX.
J5 - USART1
-----------
The boards come with a PL-2303 based USB-to-serial board. Also available
as an option is an RS-232 board. Both have the same pin out on a 6-pin
connector that mates with the upper row of J5.
PIN MODULE BOARD J5
--- ------ ---------------------------
1 5V 1 POWER Power jumper
2 GND 3 GND Ground

NOTES:
1. GPIO_OTGFS_VBUS (F107) should not be configured. No VBUS sensing
2. GPIO_OTGFS_SOF (F107) is not used
3. The OTG FS module has is own, internal soft pull-up logic. J51 should
be open so that PE11 activity does effect USB.
STM32F103 Configuration
-----------------------
System Type -> STM32 Peripheral Support
CONFIG_STM32_USB=y : Enable USB FS device
Device Drivers
CONFIG_USBDEV : USB device support
STATUS: All of the code is in place, but no testing has been performed.
STM32F107 Configuration
-----------------------
System Type -> STM32 Peripheral Support
CONFIG_STM32_OTGFS=y : Enable OTG FS
Device Drivers
CONFIG_USBDEV : USB device support
STATUS: All of the code is in place, but USB is not yet functional.
CDC/ACM Configuration
---------------------
This will select the CDC/ACM serial device. Defaults for the other
options should be okay.
Device Drivers -> USB Device Driver Support
CONFIG_CDCACM=y : Enable the CDC/ACM device
The following setting enables an example that can can be used to control
the CDC/ACM device. It will add two new NSH commands:
a. sercon will connect the USB serial device (creating /dev/ttyACM0), and
b. serdis which will disconnect the USB serial device (destroying
/dev/ttyACM0).
Application Configuration -> Examples:
CONFIG_SYSTEM_CDCACM=y : Enable an CDC/ACM example
USB MSC Configuration
---------------------
[WARNING: This configuration has not yet been verified]
The Mass Storage Class (MSC) class driver can be selected in order to
export the microSD card to the host computer. MSC support is selected:
Device Drivers -> USB Device Driver Support
CONFIG_USBMSC=y : Enable the USB MSC class driver
CONFIG_USBMSC_EPBULKOUT=1 : Use EP1 for the BULK OUT endpoint
CONFIG_USBMSC_EPBULKIN=2 : Use EP2 for the BULK IN endpoint
The following setting enables an add-on that can can be used to control
the USB MSC device. It will add two new NSH commands:
a. msconn will connect the USB serial device and export the microSD
card to the host, and
b. msdis which will disconnect the USB serial device.
Application Configuration -> System Add-Ons:
CONFIG_SYSTEM_USBMSC=y : Enable the USBMSC add-on
CONFIG_SYSTEM_USBMSC_NLUNS=1 : One LUN
CONFIG_SYSTEM_USBMSC_DEVMINOR1=0 : Minor device zero
CONFIG_SYSTEM_USBMSC_DEVPATH1="/dev/mmcsd0"
: Use a single, LUN: The microSD
: block driver.
NOTES:
a. To prevent file system corruption, make sure that the microSD is un-
mounted *before* exporting the mass storage device to the host:
nsh> umount /mnt/sdcard
nsh> mscon
The microSD can be re-mounted after the mass storage class is disconnected:
nsh> msdis
nsh> mount -t vfat /dev/mtdblock0 /mnt/at25

NOTES:
1. The STM32F107 does not support the SDIO/memory card interface. So the SD card
cannot be used with the STM32F107 (unless the pin-out just happens to match up
with an SPI-based card interface???)

CONFIG_MMSCD_NSLOTS=1 : One slot per driver instance
CONFIG_MMCSD_HAVECARDDETECT=y : Supports card-detect PIOs
CONFIG_MMCSD_MMCSUPPORT=n : Interferes with some SD cards
CONFIG_MMCSD_SPI=n : No SPI-based MMC/SD support
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
Using the SD card
-----------------
1) After booting, an SDIO device will appear as /dev/mmcsd0
2) If you try mounting an SD card with nothing in the slot, the
mount will fail:
nsh> mount -t vfat /dev/mmcsd1 /mnt/sd1
nsh: mount: mount failed: 19
STATUS: All of the code is in place, but no testing has been performed.

LCD/Touchscreen Interface
=========================
An LCD may be connected via J11. Only the the STM32F103 supports the FSMC signals
needed to drive the LCD.
The LCD features an (1) HY32D module with built-in SSD1289 LCD controller, and (a)
a XPT2046 touch screen controller.

Toolchains
==========
NOTE about Windows native toolchains
------------------------------------
There are several limitations to using a Windows based toolchain in a
Cygwin environment. The three biggest are:
1. The Windows toolchain cannot follow Cygwin paths. Path conversions are
performed automatically in the Cygwin makefiles using the 'cygpath'
utility but you might easily find some new path problems. If so, check
out 'cygpath -w'
2. Windows toolchains cannot follow Cygwin symbolic links. Many symbolic
links are used in Nuttx (e.g., include/arch). The make system works
around these problems for the Windows tools by copying directories
instead of linking them. But this can also cause some confusion for
you: For example, you may edit a file in a "linked" directory and find
that your changes had no effect. That is because you are building the
copy of the file in the "fake" symbolic directory. If you use a\
Windows toolchain, you should get in the habit of making like this:
make clean_context all
An alias in your .bashrc file might make that less painful.
3. Dependencies are not made when using Windows versions of the GCC. This is
because the dependencies are generated using Windows pathes which do not
work with the Cygwin make.
MKDEP = $(TOPDIR)/tools/mknulldeps.sh
Configurations
==============
Information Common to All Configurations
----------------------------------------
Each SAM3U-EK configuration is maintained in a sub-directory and
can be selected as follow:
cd tools
./configure.sh viewtool-stm32f107/<subdir>
cd -
. ./setenv.sh
Before sourcing the setenv.sh file above, you should examine it and perform
edits as necessary so that TOOLCHAIN_BIN is the correct path to the directory
than holds your toolchain binaries.
And then build NuttX by simply typing the following. At the conclusion of
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
make
The <subdir> that is provided above as an argument to the tools/configure.sh
must be is one of the following.
NOTES:
1. These configurations use the mconf-based configuration tool. To
change any of these configurations using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
and misc/tools/
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. Unless stated otherwise, all configurations generate console
output on USART1.
3. Unless otherwise stated, the configurations are setup for
Cygwin under Windows:
Build Setup:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
4. All of these configurations use the CodeSourcery for Windows toolchain
(unless stated otherwise in the description of the configuration). That
toolchain selection can easily be reconfigured using 'make menuconfig'.
Here are the relevant current settings:
System Type -> Toolchain:
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : GNU EABI toolchain for windows
The setenv.sh file is available for you to use to set the PATH
variable. The path in the that file may not, however, be correct
for your installation.
See also the "NOTE about Windows native toolchains" in the section call
"GNU Toolchain Options" above.
4. These configurations all assume that the STM32F107VCT6 is mounted on
board. This is configurable; you can select the STM32F103VCT6 as an
alternative.
5. These configurations all assume that you are loading code using
something like the ST-Link v2 JTAG. None of these configurations are
setup to use the DFU bootloader but should be easily reconfigured to
use that bootloader is so desired.
Configuration Sub-directories
-----------------------------
netnsh:
This configuration directory provide the NuttShell (NSH) with
networking support.
NOTES:
1. This configuration will work only on the version the viewtool
board with the the STM32F107VCT6 installed. If you have a board
with the STM32F103VCT6 installed, please use the nsh configuration
described below.
2. There is no PHY on the base viewtool stm32f107 board. You must
also have the "ViewTool DP83848 Ethernet Module" installed on J2
in order to support networking.
3. Since networking is enabled, you will see some boot-up delays when
the network connection is established. These delays can be quite
large is no network is attached (A production design to bring up the
network asynchronously to avoid these start up delays).
4. This configuration uses the default USART1 serial console. That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
5. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
6. USB support is disabled by default. See the section above entitled,
"USB Interface"
STATUS. The first time I build the configuration, I get some undefined
external references. No idea why. Simply cleaning the apps/ directory
and rebuilding fixes the problem:
make apps_clean all
nsh:
This configuration directory provide the basic NuttShell (NSH).
NOTES:
1. This configuration will work with either the version of the board
with STM32F107VCT6 or STM32F103VCT6 installed. The default
configuration is for the STM32F107VCT6. To use this configuration
with a STM32F103VCT6, it would have to be modified as follows:
System Type -> STM32 Configuration Options
CONFIG_ARCH_CHIP_STM32F103VCT6=y
CONFIG_ARCH_CHIP_STM32F107VC=n
2. This configuration uses the default USART1 serial console. That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
3. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
4. USB support is disabled by default. See the section above entitled,
"USB Interface"
3. This configured can be re-configured to use either the Viewtool LCD
module. NOTE: The LCD module can only be used on the STM32F103 version
of the board. The LCD requires FSMC support.
System Type -> STM32 Chip Selection:
CONFIG_ARCH_CHIP_STM32F103VCT6=y : Select STM32F103VCT6
System Type -> Peripherals:
CONFIG_STM32_FSMC=y : Enable FSMC LCD interface
Device Drivers -> LCD Driver Support
CONFIG_LCD=y : Enable LCD support
CONFIG_NX_LCDDRIVER=y : LCD graphics device
CONFIG_LCD_MAXCONTRAST=1
CONFIG_LCD_MAXPOWER=255
CONFIG_LCD_LANDSCAPE=y : Landscape orientation
CONFIG_LCD_SSD1289=y : Select the SSD1289
CONFIG_SSD1289_PROFILE1=y

CONFIG_NX_DISABLE_32BPP=y
Graphics Support -> Font Selections
CONFIG_NXFONTS_CHARBITS=7
CONFIG_NXFONT_SANS22X29B=y
CONFIG_NXFONT_SANS23X27=y
Application Configuration -> Examples

CONFIG_EXAMPLES_NXLINES_BORDERWIDTH=4
CONFIG_EXAMPLES_NXLINES_BORDERCOLOR=0xffe0
CONFIG_EXAMPLES_NXLINES_CIRCLECOLOR=0xf7bb
CONFIG_EXAMPLES_NXLINES_BPP=16
STATUS: Now working; reads 0x8999 as device ID. This may perhaps
be due to incorrect jumper settings
6. This configuration has been used for verifying the touchscreen on
on the Viewtool LCD module. NOTE: The LCD module can really only
be used on the STM32F103 version of the board. The LCD requires
FSMC support (the touchscreen, however, does not but the touchscreen
is not very meaningful with no LCD).
System Type -> STM32 Chip Selection:
CONFIG_ARCH_CHIP_STM32F103VCT6=y : Select STM32F103VCT6
With the following 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 SPI2 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_STM32_SPI2=y : Enable support for SPI2
RTOS Features:
CONFIG_DISABLE_SIGNALS=n : Signals are required
Library Support:
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
Applicaton Configuration:
CONFIG_EXAMPLES_TOUCHSCREEN=y : Enable the touchscreen built-int test
Defaults should be okay for related touchscreen settings. Touchscreen
debug output on USART1 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
STATUS: Working
highpri:
This configuration was used to verify the NuttX high priority, nested
interrupt feature. This is a board-specific test and probably not
of much interest now other than for reference.
This configuration targets the viewtool board with the STM32F103VCT6
mounted. It uses TIM6 to generated high rate interrupts for the test.
