| Supported Features |
| ================== |
| |
| The Zephyr stm32f103_mini 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 | |
| +-----------+------------+-------------------------------------+ |
| | CLOCK | on-chip | reset and clock control | |
| +-----------+------------+-------------------------------------+ |
| | FLASH | on-chip | flash memory | |
| +-----------+------------+-------------------------------------+ |
| | WATCHDOG | on-chip | independent watchdog | |
| +-----------+------------+-------------------------------------+ |
| | ADC | on-chip | ADC Controller | |
| +-----------+------------+-------------------------------------+ |
| | PWM | on-chip | pwm | |
| +-----------+------------+-------------------------------------+ |
| | SPI | on-chip | spi | |
| +-----------+------------+-------------------------------------+ |
| |
| Other hardware features are not yet supported in this Zephyr port. |
| |
| The default configuration can be found in the defconfig file: |
| ``boards/arm/stm32f103_mini/stm32f103_mini_defconfig`` |
| |
| Connections and IOs |
| =================== |
| |
| Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as |
| input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the |
| GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current |
| capable except for analog inputs. |

| Programming and Debugging |
| ************************* |
| |
| Applications for the ``stm32f103_mini`` board configuration can be built and |
| flashed in the usual way (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| Flashing |
| ======== |
| |
| There are 2 main entry points for flashing STM32F1X SoCs, one using the ROM |
| bootloader, and another by using the SWD debug port (which requires additional |
| hardware such as ST-Link). Flashing using the ROM bootloader requires a special activation |
| pattern, which can be triggered by using the BOOT0 pin. |
| |
| Flashing an application to stm32f103 mini |
| ----------------------------------------- |
| |
| Here is an example for the :ref:`blinky-sample` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32f103_mini |
| :goals: build flash |
| |
| You will see the LED blinking every second. |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :ref:`blinky-sample` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/basic/blinky |
| :board: stm32f103_mini |
| :maybe-skip-config: |
| :goals: debug |
