Contents ======== - Nucleo-64 Boards - Button - LED - USARTs and Serial Consoles - Configurations Nucleo-64 Boards ================ The Nucleo-F410RB board is member of the Nucleo-64 board family. The Nucleo-64 is a standard board for use with several STM32 parts in the LQFP64 package. Variants include Order code Targeted STM32 ------------- -------------- NUCLEO-F030R8 STM32F030R8T6 NUCLEO-F070RB STM32F070RBT6 NUCLEO-F072RB STM32F072RBT6 NUCLEO-F091RC STM32F091RCT6 NUCLEO-F103RB STM32F103RBT6 NUCLEO-F302R8 STM32F302R8T6 NUCLEO-F303RE STM32F303RET6 NUCLEO-F334R8 STM32F334R8T6 NUCLEO-F401RE STM32F401RET6 NUCLEO-F410RB STM32F410RBT6 NUCLEO-F411RE STM32F411RET6 NUCLEO-F446RE STM32F446RET6 NUCLEO-L053R8 STM32L053R8T6 NUCLEO-L073RZ STM32L073RZT6 NUCLEO-L152RE STM32L152RET6 NUCLEO-L452RE STM32L452RET6 NUCLEO-L476RG STM32L476RGT6 Hardware ======== Buttons ------- B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32 microcontroller. LEDs ---- The Nucleo F410RB provide a single user LED, LD2. LD2 is the green LED connected to Arduino signal D13 corresponding to MCU I/O PA5 (pin 21) or PB13 (pin 34) depending on the STM32target. - When the I/O is HIGH value, the LED is on. - When the I/O is LOW, the LED is off. 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/sam_leds.c. The LEDs are used to encode OS-related events as follows when the red LED (PE24) is available: SYMBOL Meaning LD2 ------------------- ----------------------- ----------- LED_STARTED NuttX has been started OFF LED_HEAPALLOCATE Heap has been allocated OFF LED_IRQSENABLED Interrupts enabled OFF LED_STACKCREATED Idle stack created ON LED_INIRQ In an interrupt No change LED_SIGNAL In a signal handler No change LED_ASSERTION An assertion failed No change LED_PANIC The system has crashed Blinking LED_IDLE MCU is is sleep mode Not used Thus if LD2, NuttX has successfully booted and is, apparently, running normally. If LD2 is flashing at approximately 2Hz, then a fatal error has been detected and the system has halted. Serial Consoles =============== USART1 ------ Pins and Connectors: RXD: PA11 CN10 pin 14 PB7 CN7 pin 21 TXD: PA10 CN9 pin 3, CN10 pin 33 PB6 CN5 pin 3, CN10 pin 17 NOTE: You may need to edit the include/board.h to select different USART1 pin selections. TTL to RS-232 converter connection: Nucleo CN10 STM32F410RB ----------- ------------ Pin 21 PA9 USART1_RX *Warning you make need to reverse RX/TX on Pin 33 PA10 USART1_TX some RS-232 converters Pin 20 GND Pin 8 U5V To configure USART1 as the console: CONFIG_STM32_USART1=y CONFIG_USART1_SERIALDRIVER=y CONFIG_USART1_SERIAL_CONSOLE=y CONFIG_USART1_RXBUFSIZE=256 CONFIG_USART1_TXBUFSIZE=256 CONFIG_USART1_BAUD=115200 CONFIG_USART1_BITS=8 CONFIG_USART1_PARITY=0 CONFIG_USART1_2STOP=0 USART2 ----- Pins and Connectors: RXD: PA3 CN9 pin 1 (See SB13, 14, 62, 63). CN10 pin 37 PD6 TXD: PA2 CN9 pin 2(See SB13, 14, 62, 63). CN10 pin 35 PD5 UART2 is the default in all of these configurations. TTL to RS-232 converter connection: Nucleo CN9 STM32F410RB ----------- ------------ Pin 1 PA3 USART2_RX *Warning you make need to reverse RX/TX on Pin 2 PA2 USART2_TX some RS-232 converters Solder Bridges. This configuration requires: - SB62 and SB63 Closed: PA2 and PA3 on STM32 MCU are connected to D1 and D0 (pin 7 and pin 8) on Arduino connector CN9 and ST Morpho connector CN10 as USART signals. Thus SB13 and SB14 should be OFF. - SB13 and SB14 Open: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are disconnected to PA3 and PA2 on STM32 MCU. To configure USART2 as the console: CONFIG_STM32_USART2=y CONFIG_USART2_SERIALDRIVER=y CONFIG_USART2_SERIAL_CONSOLE=y CONFIG_USART2_RXBUFSIZE=256 CONFIG_USART2_TXBUFSIZE=256 CONFIG_USART2_BAUD=115200 CONFIG_USART2_BITS=8 CONFIG_USART2_PARITY=0 CONFIG_USART2_2STOP=0 USART6 ------ Pins and Connectors: RXD: PC7 CN5 pin2, CN10 pin 19 PA12 CN10, pin 12 TXD: PC6 CN10, pin 4 PA11 CN10, pin 14 To configure USART6 as the console: CONFIG_STM32_USART6=y CONFIG_USART6_SERIALDRIVER=y CONFIG_USART6_SERIAL_CONSOLE=y CONFIG_USART6_RXBUFSIZE=256 CONFIG_USART6_TXBUFSIZE=256 CONFIG_USART6_BAUD=115200 CONFIG_USART6_BITS=8 CONFIG_USART6_PARITY=0 CONFIG_USART6_2STOP=0 Virtual COM Port ---------------- Yet another option is to use UART2 and the USB virtual COM port. This option may be more convenient for long term development, but is painful to use during board bring-up. Solder Bridges. This configuration requires: - SB62 and SB63 Open: PA2 and PA3 on STM32 MCU are disconnected to D1 and D0 (pin 7 and pin 8) on Arduino connector CN9 and ST Morpho connector CN10. - SB13 and SB14 Closed: PA2 and PA3 on STM32F103C8T6 (ST-LINK MCU) are connected to PA3 and PA2 on STM32 MCU to have USART communication between them. Thus SB61, SB62 and SB63 should be OFF. Configuring USART2 is the same as given above. Question: What BAUD should be configure to interface with the Virtual COM port? 115200 8N1? Default ------- As shipped, SB62 and SB63 are open and SB13 and SB14 closed, so the virtual COM port is enabled. Configurations ============== nsh: --------- Configures the NuttShell (nsh) located at apps/examples/nsh for the Nucleo-F410RB board. The Configuration enables the serial interfaces on UART2. Support for builtin applications is enabled, but in the base configuration no builtin applications are selected (see NOTES below). 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.
