Note: 1. The DSP library in the new CMSIS V5.6 is much more user-friendly than previous versions. 2. This post shares a method for adding source code. Previously, we used libraries, which made it inconvenient to view the source code. 3. You can also refer to the first version of the DSP tutorial, which is … Read more
Debugging with Segger Ozone What if our firmware gets stuck somewhere and printf debugging doesn’t work? What if even the startup code doesn’t work? We need a debugger. There are many options, but I recommend using Segger’s Ozone debugger. Why? Because it is standalone and does not rely on any IDE. We can provide the … Read more

Where does the speed improvement of STM32 come from? That’s right! The component that accelerates the image classification processing speed of STM32 is the Digital Signal Processor (DSP). Currently, Arm‘s Cortex-M4, Cortex-M7, Cortex-M33, and Cortex-M35P microcontroller cores all come with DSP. Compared to CPU (which excels at scheduling), DSP is very good at computations, handling … Read more
