How to configure swv itm data console in stm32cubeide?
Configuring the SWV ITM Data Console in STM32CubeIDE is a powerful technique for real-time debugging and printf-style logging with minimal performance impact. Here's a comprehensive guide. Overview: What is SWV ITM? SWV (Serial Wire Viewer) and ITM (Instrumentation Trace Macrocell) work together to provide a dedicated hardware-based profiling and debugging channel. ITM: A hardware module in the ARM Cortex-M core that allows the application to send data packets. SWV: The physical interface (uses the same SWD pins as debugging) to stream this data out. Key Advantage: No UART required, very low CPU overhead, and doesn't halt program execution. Step-by-Step Configuration Step 1: Hardware Setup Connect ST-LINK: Use a USB cable to connect your STM32 discovery / nucleo board No extra wires needed: SWV uses the existing SWD (Serial Wire Debug) connection Step 2: Project Configuration in STM32CubeIDE A.
