ViewTool STM32F103/F107
This page discusses issues unique to NuttX configurations for the ViewTool STM32F103/F107 V1.2 board. This board may be fitted with either
STM32F107VCT6, or
STM32F103VCT6
The board is very modular with connectors for a variety of peripherals. Features on the base board include:
User and Wake-Up Keys
LEDs
See http://www.viewtool.com/ for further information.
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.:

Configurations using FT80x should not enable Ethernet, CAN2 or LED
support. The LCD connector, J28 pin 9, and the upper row of J18 are
also assumed to be unused:
J8 upper row (SPI2) conflicts:
Pin 2 PB14 also used by LCD
Pin 4 PB15 also used by LCD
Pin 5 PB13 also used by Ethernet, CAN2, LCD and LED4
Pin 6 PB12 also used by Ethernet, CAN2, J28 pin 9, and LED3
J8 lower row (SPI1) conflicts:
Pin 9 PA6 also used by J8 pin 9 and LED1
Pin 10 PA7 also used Ethernet
Pin 11 PA5 also used by J8 pin 7
Pin 12 PA4 also used by J8 pin 5 (J8 pin 5 not used)
J18 upper row is not used in this configuration. Cannot be used with
SPI1. Not used with SPI2 because SPI2 has the same conflicts as the
lower row so why bother?
Pin 5 PA4 also used by SPI1/NSS1
Pin 7 PA5 also used by SPI1/SCK1
Pin 9 PA6 also used by SPI1/MOSI1 and LED1
J18 lower row conflicts:
Pin 6 PC5 also used by Ethernet and the LCD interface
Pin 8 PA1 also used by Ethernet
Pin 10 PA0 also used by Ethernet and Wake-up button (not used)
Remapped SPI1 pins are not supported, but that would permit these options:
PA15/NSS1 also used by LCD
PB3/SCK1 also used by USART1 and JTAG
PB4/MISO1 also used by JTAG
PB5/MOSI1 also used by USART1, Ethernet, and J28 pin 10
There is a LM4864 audio amplifier on board so audio outputs are ready for
use with a small 1W 8Ohm speaker. GPIO0 should be configured as an
output because it is used to control the shutdown pin of the LM4864 audio
output.
GPIO0 is not connected.
This display should have:

Toolchains
NOTE about Windows native toolchains
There are several limitations to using a Windows based toolchain in a Cygwin environment. The three biggest are:
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’
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 aWindows 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.
Configurations
Information Common to All Configurations
Each SAM3U-EK configuration is maintained in a sub-directory and can be selected as follow:
tools/configure.sh viewtool-stm32f107:<subdir>
Before starting the build, make sure that your PATH environment variable includes the correct path to your toolchain.
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
see additional README.txt files in the NuttX tools repository.
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 ARM EABI GCC toolchain for Windows
(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_ARM_TOOLCHAIN_GNU_EABI=y : GNU EABI toolchain for Windows
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 if so desired.
Configuration Sub-directories
f80x
This configuration was added in order to verify the FTDI/Bridgetick Ft80x driver using apps/examples/ft80x with apps/graphics/ft80x. It is very similar to the NSH configuration with support for the FTDI FT80x LCD enabled on SPI1.
This configuration is properly setup for the MikroElektronika ConnectEVE LCD. To use the Reverdi FT801 LCD, the following changes would be required to the configuration:
-CONFIG_LCD_FT800=y
+CONFIG_LCD_FT801=y
-CONFIG_LCD_FT80X_AUDIO_GPIOSHUTDOWN=y
-CONFIG_LCD_FT80X_AUDIO_GPIO=0
+CONFIG_LCD_FT80X_AUDIO_NOSHUTDOWN=y
-CONFIG_EXAMPLES_FT80X_DEVPATH="/dev/ft800"
+CONFIG_EXAMPLES_FT80X_DEVPATH="/dev/ft801"
- STATUS::
- 2018-03-09: The ConnectEVE display is basically working. There are
some specific issues with some of the demos in apps/examples/ft80x that still need to be addressed. I have the Riverdi display FT801 display in hand as well, but have not tested with the display yet.
I have seen issues also where the board does not recover after a reset. It required a full power cycle to get functionality back. This is not too surprising since there is no reset signal to the FT80x (there is power down/up). It might be necessary to perform a software reset of the FT80x during initialization.
- 1028-03-10: Most of issues have been worked out in the FT80x demos
and the driver appears 100% functional.
netnsh
This configuration directory provide the NuttShell (NSH) with networking support.
- NOTES::
This configuration will work only on the version the viewtool board with the STM32F107VCT6 installed. If you have a board with the STM32F103VCT6 installed, please use the nsh configuration described below.
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.
Since networking is enabled, you will see some boot-up delays when the network connection is established. These delays can be quite large if no network is attached (A production design to bring up the network asynchronously to avoid these start up delays).
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.
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_ARM_TOOLCHAIN_GNU_EABI=y : GNU EABI toolchain for Windows
USB support is disabled by default. See the section above entitled, “USB Interface”
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_STM32F103VC=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_ARM_TOOLCHAIN_GNU_EABI=y : GNU EABI toolchain 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_STM32F103VC=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
Graphics Support
CONFIG_NX=y
Graphics Support -> Supported Pixel Depths
CONFIG_NX_DISABLE_1BPP=y : Only 16BPP supported
CONFIG_NX_DISABLE_2BPP=y
CONFIG_NX_DISABLE_4BPP=y
CONFIG_NX_DISABLE_8BPP=y
CONFIG_NX_DISABLE_24BPP=y
CONFIG_NX_DISABLE_32BPP=y
Graphics Support -> Font Selections
CONFIG_NXFONTS_CHARBITS=7
CONFIG_NXFONT_SANS22X29B=y
CONFIG_NXFONT_SANS23X27=y

CONFIG_EXAMPLES_NXLINES_CIRCLECOLOR=0xf7bb
CONFIG_EXAMPLES_NXLINES_BPP=16
STATUS: Not 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_STM32F103VC=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_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
Library Support:
CONFIG_SCHED_WORKQUEUE=y : Work queue support required
Application 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_FEATURES=y : Enable debug features
CONFIG_DEBUG_INFO=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
tcpblaster
The tcpblaster example derives from the nettest example and basically duplicates that application when the nettest PERFORMANCE option is selected. tcpblaster has a little better reporting of performance stats, however.
This configuration derives directly from the netnsh configuration and most of the notes there should apply equally here.
General usage instructions: 1. On the host:
cd to apps/examples/tcpblaster
Run the host tcpserver[.exe] program that was built in that directory
On the target:
Run the tcpclient built in application.
When you get tire of watch the numbers scroll by, just kill the tcpserver on the host.
