Nucleo C542RC

Overview

The STM32 Nucleo-64 development board with STM32C542RC MCU, supports Arduino and ST morpho connectivity.

The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features provided by the STM32 microcontroller. For the compatible boards, the internal or external SMPS significantly reduces power consumption in Run mode.

The ARDUINO® Uno V3 connectivity support and the ST morpho headers allow the easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo-64 board does not require any separate probe as it integrates the ST-LINK debugger/programmer.

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.

For more details please refer to STM32 Nucleo-64 board User Manual [3].

Programming and Debugging

The nucleo_c542rc board supports the runners and associated west commands listed below.

flash debug

Nucleo C542RC board includes an STLINK-V3EC embedded debug tool interface.

Applications for the nucleo_c542rc board 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, an external JLink (Software and Documentation Package Version >= v8.12e) can also be used to flash the board using the --runner option:

$ west flash --runner jlink

Flashing an application to Nucleo C542RC

Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b nucleo_c542rc samples/basic/blinky
west flash

You will see the LED blinking every second.

Debugging

You can debug an application in the usual way using the ST-LINK GDB Server. Here is an example for the Blinky application.

# From the root of the zephyr repository
west build -b nucleo_c542rc samples/basic/blinky
west debug
