A121 STM32CubeIDE User Guide
A technical guide for integrating the Acconeer A121 radar sensor with STM32CubeIDE, covering project setup, pin configuration, and software integration for the XM125 and XE121.
Overview
This user guide provides comprehensive instructions for integrating the Acconeer A121 pulsed coherent radar sensor into the STM32CubeIDE development environment. Using the Nucleo-L476RG board and XE121 evaluation kit as primary examples, the document details MCU selection, project initialization, and specific pin configurations for SPI and GPIO interfaces. It outlines the process of adding Acconeer SDK source files, headers, and libraries to a project, configuring UART for print functionality, and selecting appropriate HAL integration files. Additionally, the guide provides troubleshooting steps for common development issues including sensor creation failures, SPI communication errors, and heap memory corruption.
Use Cases
- Project setup for A121 radar sensors in STM32CubeIDE
- Configuring SPI and GPIO for XE121 evaluation boards
- Integrating Acconeer SDK libraries into STM32 projects
