In embedded development, delay functions are fundamental operations. However, when faced with microsecond-level precision requirements, the choice between loop delays and timer solutions directly affects system stability. 1. Loop Delay: A Legacy from the Bare-Metal Era Implementation Principle: Consumes CPU cycles through no-operation instructions (such as NOP) or decrement loops. Critical Flaw: Precision fluctuation > … Read more

NXP microcontrollers (such as Kinetis and LPC series) feature a module related to keyboard input called KBI (Keyboard Interrupt Module), which implements most of its functions that can also be achieved by microcontrollers from other brands. The difference is that the latter consumes more software or hardware resources (besides the MCU), and to highlight versatility, … Read more
In today’s rapidly developing fields of artificial intelligence and the Internet of Things, microcontrollers (Single Chip Microcontrollers) still play an indispensable role. Whether in smart homes, industrial automation, or wearable devices, microcontrollers remain the “unsung heroes” of the hardware world. Today, we will discuss the “hardcore strength” of microcontrollers and how they have become the … Read more
Many students are puzzled when controlling motors, as the microcontroller pins can output high and low levels. Why can’t we connect the motor directly to make it turn? Why is a driver necessary? What is its purpose? There are so many different driver models. Is it possible to operate without one? Today, let’s discuss this. … Read more
