| The Zephyr stm32f411e_disco board configuration supports the following |
| hardware features: |
| |
| +-----------+------------+-------------------------------------+ |
| | Interface | Controller | Driver/Component | |
| +===========+============+=====================================+ |
| | NVIC | on-chip | nested vector interrupt controller | |
| +-----------+------------+-------------------------------------+ |
| | UART | on-chip | serial port-polling; | |
| | | | serial port-interrupt | |
| +-----------+------------+-------------------------------------+ |
| | PINMUX | on-chip | pinmux | |
| +-----------+------------+-------------------------------------+ |
| | GPIO | on-chip | gpio | |
| +-----------+------------+-------------------------------------+ |
| | PWM | on-chip | pwm | |
| +-----------+------------+-------------------------------------+ |
| |
| Other hardware features are not yet supported on Zephyr porting. |
| |
| The default configuration can be found in the defconfig file |
| :zephyr_file:`boards/arm/stm32f411e_disco/stm32f411e_disco_defconfig` |
| |
| |
| Pin Mapping |
| =========== |
| |
| STM32F411E-DISCO Discovery kit has 5 GPIO controllers. These controllers are |
| responsible for pin muxing, input/output, pull-up, etc. |
| |
| For mode details please refer to `32F411EDISCOVERY board User Manual`_. |
| |
| Default Zephyr Peripheral Mapping: |
| ---------------------------------- |
| - UART_2_TX : PA2 |
| - UART_2_RX : PA3 |
| - LD3 : PD13 (PWM4 CH2) |
| - LD4 : PD12 (PWM4 CH1) |
| - LD5 : PD14 (PWM4 CH3) |
| - LD6 : PD15 (PWM4 CH4) |
| |
| System Clock |
| ============ |
| |
| STM32F411E-DISCO System Clock could be driven by an internal or external |
| oscillator, as well as the main PLL clock. By default, the System clock is |
| driven by the PLL clock at 100MHz, driven by the internal oscillator. |
| |
| Serial Port |
| =========== |
| |
| The STM32F411G Discovery kit has up to 3 UARTs. The Zephyr console output is |
| assigned to UART2. Default settings are 115200 8N1. |

| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``stm32f411e_disco`` board configuration can be built and |
| flashed in the usual way (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Flashing |
| ======== |
| |
| STM32F411E-DISCO Discovery kit includes an ST-LINK/V2 embedded debug tool |
| interface. This interface is supported by the openocd version included in |
| Zephyr SDK. |
| |
| Flashing an application to STM32F411E-DISCO |
| ------------------------------------------- |
| |
| Connect the STM32F411E-DISCO Discovery kit to your host computer using the |
| USB port. Then build and flash an application. |
| |
| Here is an example for the :ref:`blinky-sample` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32f411e_disco |
| :goals: build flash |
| |
| In case you are using PCB revision B, you have to use an |
| adapted board definition as the default PCB rev here is D: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32f411e_disco@B |
| :goals: build flash |
| |
| You should see the orange led (LD3) blinking every second. |
| |
| Debugging |
| ========= |
| |
| You can debug applications in the usual way. Here is an example for |
| the :ref:`blinky-sample` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32f411e_disco |
| :maybe-skip-config: |
| :goals: debug |
