+LEDs
+====
+
+The STM32F103 Minimum board has only one software controllable LED.
+This LED can be used by the board port when CONFIG_ARCH_LEDS option is
+enabled.
+
+If enabled the LED is simply turned on when the board boots
+succesfully, and is blinking on panic / assertion failed.

+
+STM32F103 Minimum - specific Configuration Options
+===============================================
+
+ CONFIG_ARCH - Identifies the arch/ subdirectory. This should
+ be set to:
+
+ CONFIG_ARCH=arm
+
+ CONFIG_ARCH_family - For use in C code:
+
+ CONFIG_ARCH_ARM=y
+
+ CONFIG_ARCH_architecture - For use in C code:
+
+ CONFIG_ARCH_CORTEXM3=y
+
+ CONFIG_ARCH_CHIP - Identifies the arch/*/chip subdirectory
+
+ CONFIG_ARCH_CHIP=stm32
+
+ CONFIG_ARCH_CHIP_name - For use in C code to identify the exact
+ chip:
+
+ CONFIG_ARCH_CHIP_STM32F103C8=y
+
+ CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG - Enables special STM32 clock
+ configuration features.
+
+ CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=n
+
+ CONFIG_ARCH_BOARD - Identifies the configs subdirectory and
+ hence, the board that supports the particular chip or SoC.
+
+ CONFIG_ARCH_BOARD=stm32f103-minium
+
+ CONFIG_ARCH_BOARD_name - For use in C code
+
+ CONFIG_ARCH_BOARD_STM32_MINIMUM=y
+
+ CONFIG_ARCH_LOOPSPERMSEC - Must be calibrated for correct operation
+ of delay loops
+
+ CONFIG_ENDIAN_BIG - define if big endian (default is little
+ endian)
+
+ CONFIG_RAM_SIZE - Describes the installed DRAM (SRAM in this case):
+
+ CONFIG_RAM_SIZE=20480 (20Kb)
+
+ CONFIG_RAM_START - The start address of installed DRAM
+
+ CONFIG_RAM_START=0x20000000
+
+ CONFIG_ARCH_LEDS - Use LEDs to show state. Unique to boards that
+ have LEDs
+
+ CONFIG_ARCH_INTERRUPTSTACK - This architecture supports an interrupt
+ stack. If defined, this symbol is the size of the interrupt
+ stack in bytes. If not defined, the user task stacks will be
+ used during interrupt handling.
+
+ CONFIG_ARCH_STACKDUMP - Do stack dumps after assertions
+
+ CONFIG_ARCH_CALIBRATION - Enables some build in instrumentation that
+ cause a 100 second delay during boot-up. This 100 second delay
+ serves no purpose other than it allows you to calibratre
+ CONFIG_ARCH_LOOPSPERMSEC. You simply use a stop watch to measure
+ the 100 second delay then adjust CONFIG_ARCH_LOOPSPERMSEC until
+ the delay actually is 100 seconds.
+
+ Individual subsystems can be enabled:

+
+ Timer devices may be used for different purposes. One special purpose is
+ to generate modulated outputs for such things as motor control. If CONFIG_STM32_TIMn
+ is defined (as above) then the following may also be defined to indicate that
+ the timer is intended to be used for pulsed output modulation or ADC conversion.
+ Note that ADC require two definitions: Not only do you have
+ to assign the timer (n) for used by the ADC, but then you also have to
+ configure which ADC (m) it is assigned to.
+
+ CONFIG_STM32_TIMn_PWM Reserve timer n for use by PWM, n=1,..,14
+ CONFIG_STM32_TIMn_ADC Reserve timer n for use by ADC, n=1,..,14
+ CONFIG_STM32_TIMn_ADCm Reserve timer n to trigger ADCm, n=1,..,14, m=1,..,3
+
+ For each timer that is enabled for PWM usage, we need the following additional
+ configuration settings:
+
+ CONFIG_STM32_TIMx_CHANNEL - Specifies the timer output channel {1,..,4}
+
+ NOTE: The STM32 timers are each capable of generating different signals on
+ each of the four channels with different duty cycles. That capability is
+ not supported by this driver: Only one output channel per timer.
+
+ JTAG Enable settings (by default only SW-DP is enabled):
+
+ CONFIG_STM32_JTAG_FULL_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+ CONFIG_STM32_JTAG_NOJNTRST_ENABLE - Enables full SWJ (JTAG-DP + SW-DP)
+ but without JNTRST.
+ CONFIG_STM32_JTAG_SW_ENABLE - Set JTAG-DP disabled and SW-DP enabled
+
+ STM32F103 Minimum specific device driver settings
+
+ CONFIG_U[S]ARTn_SERIAL_CONSOLE - selects the USARTn (n=1,2,3)
+ for the console and ttys0 (default is the USART1).
+ CONFIG_U[S]ARTn_RXBUFSIZE - Characters are buffered as received.
+ This specific the size of the receive buffer
+ CONFIG_U[S]ARTn_TXBUFSIZE - Characters are buffered before
+ being sent. This specific the size of the transmit buffer
+ CONFIG_U[S]ARTn_BAUD - The configure BAUD of the UART. Must be
+ CONFIG_U[S]ARTn_BITS - The number of bits. Must be either 7 or 8.
+ CONFIG_U[S]ARTn_PARTIY - 0=no parity, 1=odd parity, 2=even parity
+ CONFIG_U[S]ARTn_2STOP - Two stop bits
+
+ STM32F103 Minimum CAN Configuration
+
+ CONFIG_CAN - Enables CAN support (one or both of CONFIG_STM32_CAN1 or
+ CONFIG_STM32_CAN2 must also be defined)
+ CONFIG_CAN_EXTID - Enables support for the 29-bit extended ID. Default
+ Standard 11-bit IDs.
+ CONFIG_CAN_FIFOSIZE - The size of the circular buffer of CAN messages.
+ Default: 8
+ CONFIG_CAN_NPENDINGRTR - The size of the list of pending RTR requests.
+ Default: 4
+ CONFIG_CAN_LOOPBACK - A CAN driver may or may not support a loopback
+ mode for testing. The STM32 CAN driver does support loopback mode.
+ CONFIG_CAN1_BAUD - CAN1 BAUD rate. Required if CONFIG_STM32_CAN1 is defined.
+ CONFIG_CAN2_BAUD - CAN1 BAUD rate. Required if CONFIG_STM32_CAN2 is defined.
+ CONFIG_CAN_TSEG1 - The number of CAN time quanta in segment 1. Default: 6
+ CONFIG_CAN_TSEG2 - the number of CAN time quanta in segment 2. Default: 7
+ CONFIG_CAN_REGDEBUG - If CONFIG_DEBUG is set, this will generate an
+ dump of all CAN registers.
+
+ STM32F103 Minimum SPI Configuration
+
+ CONFIG_STM32_SPI_INTERRUPTS - Select to enable interrupt driven SPI
+ support. Non-interrupt-driven, poll-waiting is recommended if the
+ interrupt rate would be to high in the interrupt driven case.
+ CONFIG_STM32_SPI_DMA - Use DMA to improve SPI transfer performance.
+ Cannot be used with CONFIG_STM32_SPI_INTERRUPT.
+
+Configurations
+==============
+
+Each STM32F103 Minimum configuration is maintained in a sub-directory and
+can be selected as follow:
+
+ cd tools
+ ./configure.sh STM32F103 Minimum/
+ cd -
+ . ./setenv.sh
+
+If this is a Windows native build, then configure.bat should be used
+instead of configure.sh:
+
+ configure.bat STM32F103-Minimum\
+
+Where is one of the following:
+
+ nsh:
+ ---
+ Configures the NuttShell (nsh) located at apps/examples/nsh. This
+ configuration enables a console on UART1. Support for
+ builtin applications is enabled, but in the base configuration no
+ builtin applications are selected.
+
+ usbnsh:
+ -------
+
+ This is another NSH example. If differs from other 'nsh' configurations
+ in that this configurations uses a USB serial device for console I/O.
+
+ NOTES:
+
+ 1. This configuration uses the mconf-based configuration tool. To
+ change this configuration 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. By default, this configuration uses the CodeSourcery toolchain
+ for Windows and builds under Cygwin (or probably MSYS). That
+ can easily be reconfigured, of course.
+
+ CONFIG_HOST_WINDOWS=y : Builds under Windows
+ CONFIG_WINDOWS_CYGWIN=y : Using Cygwin
+ CONFIG_ARMV7M_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
+
+ 3. This configuration does have UART2 output enabled and set up as
+ the system logging device:
+
+ CONFIG_SYSLOG=y : Enable output to syslog, not console
+ CONFIG_SYSLOG_CHAR=y : Use a character device for system logging
+ CONFIG_SYSLOG_DEVPATH="/dev/ttyS0" : UART2 will be /dev/ttyS0
+
+ However, there is nothing to generate SYLOG output in the default
+ configuration so nothing should appear on UART2 unless you enable
+ some debug output or enable the USB monitor.
+
+ 4. Enabling USB monitor SYSLOG output. If tracing is enabled, the USB
+ device will save encoded trace output in in-memory buffer; if the
+ USB monitor is enabled, that trace buffer will be periodically
+ emptied and dumped to the system loggin device (UART2 in this
+ configuraion):
+
+ CONFIG_USBDEV_TRACE=y : Enable USB trace feature
+ CONFIG_USBDEV_TRACE_NRECORDS=128 : Buffer 128 records in memory
+ CONFIG_NSH_USBDEV_TRACE=n : No builtin tracing from NSH
+ CONFIG_NSH_ARCHINIT=y : Automatically start the USB monitor
+ CONFIG_SYSTEM_USBMONITOR=y : Enable the USB monitor daemon
+ CONFIG_SYSTEM_USBMONITOR_STACKSIZE=2048 : USB monitor daemon stack size
+ CONFIG_SYSTEM_USBMONITOR_PRIORITY=50 : USB monitor daemon priority
+ CONFIG_SYSTEM_USBMONITOR_INTERVAL=2 : Dump trace data every 2 seconds
+
+ CONFIG_SYSTEM_USBMONITOR_TRACEINIT=y : Enable TRACE output
+ CONFIG_SYSTEM_USBMONITOR_TRACECLASS=y
+ CONFIG_SYSTEM_USBMONITOR_TRACETRANSFERS=y
+ CONFIG_SYSTEM_USBMONITOR_TRACECONTROLLER=y
+ CONFIG_SYSTEM_USBMONITOR_TRACEINTERRUPTS=y
+
+ 5. By default, this project assumes that you are *NOT* using the DFU
+ bootloader.
+
+ Using the Prolifics PL2303 Emulation
+ ------------------------------------
+ You could also use the non-standard PL2303 serial device instead of
+ the standard CDC/ACM serial device by changing:
+
+ CONFIG_CDCACM=y : Disable the CDC/ACM serial device class
+ CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is NOT the console
+ CONFIG_PL2303=y : The Prolifics PL2303 emulation is enabled
+ CONFIG_PL2303_CONSOLE=y : The PL2303 serial device is the console
