1 Introduction The Hardware Abstraction Layer (HAL) is an interface layer located between the operating system kernel and the hardware circuitry, aimed at abstracting the hardware. It hides the hardware interface details specific to a platform, providing a virtual hardware platform for the operating system, making it hardware-independent and portable across various platforms. The HAL … Read more

Introduction This sharing is just an entry-level tutorial for controlling an LED using the CC2530 microcontroller. As the first code tutorial in this Zigbee series, there are a few points to explain: This is my first time encountering Zigbee, so I will share while learning, and the sharing intervals will become uncertain. I am using … Read more
0 Introduction Before discussing Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC), let’s first clarify what analog signals and digital signals are. Analog signals can be understood as physical quantities from the real world, but these quantities are electrical signals. For example, radio signals, etc. The characteristics of analog signals are that … Read more
Abstract: This paper proposes a design method and specific implementation plan for a control system based on dual STM32 chips. The control system uses two STM32F107VCT6 chips as master and slave controllers, communicating via a high-speed SPI interface to ensure real-time performance during the control phase. The hardware layout of the system is introduced, and … Read more
