What is MCUViewer? To put it simply: MCUViewer is a real-time visualization debugging tool specifically designed for STM32 (and other Cortex-M chips). Originally named STMViewer, it was open-source until version 1.1.0, after which it became closed-source, but the source code can still be found here. It consists of two modules: • Variable Viewer: It retrieves … Read more
What is MCUViewer?MCUViewer (formerly STMViewer) is a GUI debugging tool specifically designed for MCU developers, consisting of two core modules: Module Main Functionality Applicable Scenarios Variable Viewer Real-time reading of variable values in RAM, supporting plotting, logging, and manual value modification Monitoring global variables, debugging algorithm parameters Trace Viewer Parsing SWO traces, displaying high-frequency signals, … Read more
What is MCUViewer?MCUViewer (formerly STMViewer) is an open-source GUI debugging tool specifically designed for MCUs, especially the Cortex-M series. It combines two powerful modules into a single window: Module Main Functionality Variable Viewer Real-time reading, displaying, recording, and even rewriting global variables in RAM Trace Viewer Outputs high-frequency signals, function execution time, etc., in waveform … Read more
Click on the target device selection. If there is no response, it means the device library is not configured.The configuration method is as follows: Copy JLinkDevices.xml JLink_x64.dll JLinkARM.dll three files to the bin directory.After copying, unplug and replug the J-Link. If clicking the three dots shows the device library, it means the addition was successful. … Read more
IntroductionIs debugging STM32 giving you a headache lately? UART printing is too slow and resource-consuming, and you have to set breakpoints just to check variables. Not to mention, tracking high-frequency signals is nearly impossible… Don’t worry, today I want to introduce you to a powerful tool—MCUViewer—that will completely liberate your debugging process. What is MCUViewer?MCUViewer … Read more
Hey, embedded friends, are you still logging with UART, watching the serial output scroll line by line, which is tedious and time-consuming? Have you ever thought: what if there was a visual tool that could help you instantly understand variable changes and function execution times, could the debugging experience be elevated? The answer is — … Read more
