1. Introduction This is a module for signal acquisition and computation built a couple of days ago using the H7B0 microcontroller, which uses its 16-bit ADC to capture signals and perform spectrum analysis, with results displayed on an OLED screen. Calculating a 2048-point FFT takes about 10 milliseconds. Next, let’s test if the computation speed … Read more

SystemView is an embedded system visualization analysis tool that provides complete insights into applications, including visual windows for timelines, CPU load, runtime information, and context runtime information, helping developers gain an in-depth understanding of application runtime behavior. It supports μC/OS-II, μC/OS-III, FreeRTOS, embOS, and bare-metal systems without an OS, allowing for a deep understanding of … Read more
The Cortex-M architecture uses a vector table lookup mechanism. When an exception occurs, the core automatically looks up the entry address of the handler from the vector table. The vector table is essentially an array of WORDs (32-bit integers), where each index corresponds to a specific exception, and the value of that index is the … Read more
