Recently, GigaDevice officially launched its new entry-level MCU—the GD32C231 series. As a leading player in the domestic MCU field, GigaDevice is targeting the 32-bit “low-end” market with a succinct summary:“Affordable yet fully equipped, performance maximized”.. What Makes It “High-Performance”? First, let’s look at the core parameters: the GD32C231 is equipped with theArm Cortex-M23 core, with … Read more
As a “jack of all trades” in the embedded field, the configuration of high-speed interfaces in STM32 directly determines the data throughput capability of devices. From USB 3.0 to Gigabit Ethernet, what high-speed communication features are hidden in different series and models? This article gets to the core, listing key interfaces and technical parameters. USB … 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
