“In a journey of three people, there must be my teacher among them. Choose the good ones to follow, and correct the bad ones.” The teardown of the actual device reveals that the micro design will provide designers who continuously pursue industry-leading design solutions with a “different” good design scheme, enabling quick application and bringing … Read more
In embedded development, handling asynchronous events is an unavoidable challenge. For instance, reading sensor data from an accelerometer to calculate steps, or triggering RTOS context switches via timers, all rely on the support of exception handling mechanisms. Today, we will discuss the exception handling model of ARM Cortex-M. The Core of Exception Handling In the … Read more
