Hello example for NUCLEO-G474RE

Simple "Hello World" example for STMicroelectronics NUCLEO-G474RE development board. This example prints Hello World and a counter value via the standard output which is routed to the debug console through a virtual COM port.

Prerequisites

The following tools need to be installed on your machine:

• CMSIS-Toolbox v2.12.0 or newer.
• Arm Compiler for Embedded (automatically installed via vcpkg when using Visual Studio Code).
• Microsoft Visual Studio Code with Keil Studio Pack extension.

Build the example

Using Visual Studio Code with extensions

Required tools described in file vcpkg-configuration.json should be automatically installed by vcpkg. You can see the status of vcpkg in the status bar.

Required CMSIS packs need to be also installed. In case a required pack is missing, a notification window will pop-up to install the missing pack.

Open the 'CMSIS' view from the side bar, select desired 'Build Type' and press the 'Build' button.

Using Command Line Interface (CLI)

Download required packs (not required when the packs are already available) by executing the following commands:

csolution list packs -s hello.csolution.yml -m > packs.txt
cpackget update-index
cpackget add -f packs.txt

Build the project by executing the following command:

cbuild hello.csolution.yml

Run the example

Run in Visual Studio Code

• Connect the board's ST-LINK USB to the PC (provides also power).
• Open the 'CMSIS' view from the side bar:
  • Press the 'Run' button and wait until the image is programmed and starts running.

Using Drag-and-drop programming or external programmer and terminal

• Connect the board's ST-LINK USB to the PC (provides also power).
• Program the image (.hex) using drag-and-drop programming or use an external programmer.
• Open a terminal on the PC and connect to the board's serial port with 115200 baud rate.
• Observe the terminal output.

Debug the example

Before starting to debug the application, make sure that you have gone through the steps as described in the run the application section.

Debug in Visual Studio Code

Open the CMSIS view from the side bar and press the Debug button. In the Debug view, use the SERIAL MONITOR to connect to the board's serial port with 115200 baud rate and observe the output.
