Background Knowledge of Communication Interfaces Ways of Communication Between Devices Generally, the communication methods between devices can be divided into parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the direction of data transmission, it can be divided into: … Read more
In STM32 microcontrollers, the microcontroller is equipped with a USB interface, designed to facilitate high-speed data transfer and communication between devices. The USB interface can be divided into two roles: Host and Device. So, how does STM32 control USB? 1. USB Device Function Control Enable USB device functionality: Enable the USB device functionality in CubeMX … Read more
Little Science Gas Station In embedded learning, the STM32 series chips are particularly favored due to their many excellent features, such as the STM32 MCU integrating a wealth of peripherals, including communication interfaces (like UART, SPI, I2C, CAN, etc.), analog and digital interfaces, timers, and interrupt controllers. Today, Little Science introduces the interrupt system of … Read more
This Saturday (September 7), I will join Teacher Xintian (the head of the embedded course) to participate in the STM32 national tour seminar in Nanjing. First, let me introduce that STM32 is a series of 32-bit microcontrollers (MCUs) produced by STMicroelectronics, designed with an ARM Cortex-M core, known for its high performance, low power consumption, … Read more
Miniware’s DS203 is one of the earlier mini oscilloscopes in China, followed by others like ZYBO and DreamSource. I bought this DS203 in 2014, and it is already 10 years old… Let’s open it up and appreciate the internal materials. The entire body is made of aluminum alloy CNC, with four hex screws at the … Read more
