STM32F0 Discovery
Overview
The STM32F0 Discovery development board uses an STM32F051R8T6 MCU and integrates the ST-LINK/V2-1 debugger and programmer. It also comes with a comprehensive STM32 software HAL library and various packaged software examples.
More information about the board can be found at the STM32F0DISCOVERY website [1].
Hardware
The STM32 Discovery board features:
STM32F051R8T6 microcontroller featuring 64 KB Flash memory, 8 KB RAM in an LQFP64 package
On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone ST-LINK/V2 (with SWD connector for programming and debugging)
Board power supply: through USB bus or from an external 5 V supply voltage
External application power supply: 3 V and 5 V
Four LEDs:
LD1 (red) for 3.3 V power on
LD2 (red/green) for USB communication
LD3 (green) for PC9 output
LD4 (blue) for PC8 output
Two push buttons (user and reset)
Extension header for all LQFP64 I/Os for quick connection to prototyping board and easy probing
An additional board is provided which can be connected to the extension connector for even easier prototyping and probing.
Comprehensive free software including a variety of examples, part of STM32CubeF0 package or STSW-STM32049 for legacy Standard Libraries usage
More information about STM32F051R8 can be found in the STM32F0x8 reference manual [2].

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.
Default Zephyr Peripheral Mapping:
UART_1_TX : PA9
UART_1_RX : PA10
UART_2_TX : PA2
UART_2_RX : PA3
For more details please refer to STM32F0DISCOVERY board User Manual [3].
Programming and Debugging
STM32F0DISCOVERY board includes an ST-LINK/V2-1 embedded debug tool interface.
Applications for the stm32f0_disco board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
Flashing
The board is configured to be flashed using west STM32CubeProgrammer [4] runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to Nucleo F030R8
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b stm32f0_disco samples/basic/blinky
west 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 Blinky application.
# From the root of the zephyr repository
west build -b stm32f0_disco samples/basic/blinky
west debug
