| ST ST25DV Discovery, MB1283 version |
| ################################### |
| |
| Overview |
| ******** |
| |
| The ST25DV04K device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a |
| 4 Kbits EEPROM memory. It can be operated from an I2C interface, or by a 13.56 MHz |
| RFID reader, or by a NFC phone. The ST25DV04K Class 5 antenna daughter card, included |
| in the kit, can be replaced by Class 1 or Class 6 antennas. |
| |
| The ST25DV-DISCOVERY is a demonstration kit to evaluate the features and capabilities |
| of the ST25DV series. |
| It is based on the NFC ST25DV04K device embedded on a daughter card using a Class 5 antenna |
| and a STM32 processor driving a mother board. |

| |
| Hardware |
| ******** |
| |
| The ST25DV Discovery kit provides the following hardware components: |
| |
| - Main board: ST25DV_Discovery_Mboard: |
| |
| - STM32F405VGT6 LQFP100 32-bit microcontroller, with 1 Mbyte Flash memory, 192 + 4 Kbytes SRAM. |
| - LCD color screen (320 x 200 pixels) |
| - Touch screen driver |
| - Different color LEDs (power, user, ST link) |
| - User push button |
| - Joystick for menu selection |
| - Reset button |
| - On board ST link for microcontroller firmware upgrade and debug |
| - ST link mini USB |
| - User micro USB |
| - USB micro or mini connector for board powering |
| - Demonstration edition (optional add-on module) with Bluetooth Low Energy module, |
| Wi-Fi ® module and JTAG 20 pin connector |
| |
| It exists in two variants, MB1283 and MB1285. |
| |
| - Antenna daughter board: ST25DV_Discovery_ANT_C5: |
| |
| - 40 mm x 24 mm, 13.56 MHz inductive antenna etched on the PCB |
| - ST25DV04K Dynamic NFC / RFID tag |
| - I 2 C interface connector |
| - Energy harvesting output (VOUT) with a 10nF capacitance filtering circuit |
| - GPO configurable as RF WIP/BUSY output, to indicate that an RF operation is ongoing |
| |
| The antenna board can be removed, and its 14-pin 0.254mm header connector used as an eval kit header. |
| |
| Connections and IOs |
| =================== |
| |
| Default Zephyr Peripheral Mapping |

| Serial Port |
| =========== |
| |
| The Zephyr console output and shell are assigned to UART6, which is connected to the |
| onboard ST-LINK/V2 Virtual COM port interface. |
| Default communication settings are 115200 8N1. |
| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``st25dv_mb1283_disco`` board configuration can be built and |
| flashed in the usual way (see :ref:`build_an_application` and |
| :ref:`application_run` for more details). |
| |
| If programming fails, press the reset button (black) and release it while "west flash" is running. |
| |
| Flashing |
| ======== |
| |
| ST25DV Discovery kit includes an ST-LINK/V2 embedded debug tool interface. |
| This interface is supported by the openocd version included in the Zephyr SDK. |
| |
| Flashing an application to ST25DV Discovery |
| -------------------------------------------- |
| |
| First, connect the ST25DV Discovery kit to your host computer using |
| the USB port to prepare it for flashing. Then build and flash your application. |
| |
| Here is an example for the :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: st25dv_mb1283_disco |
| :goals: build flash |
| |
| Run a serial host program to connect with your board: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| Hello World! st25dv_mb1283_disco |
| |
| Debugging |
| ========= |
| |
| You can debug an application in the usual way. Here is an example for the |
| :ref:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: st25dv_mb1283_disco |
| :goals: debug |
