Click the Blue Text Follow Us 1. What is SPI SPI stands for Serial Peripheral Interface, which is a serial interface for peripheral devices. SPI is a high-speed, full-duplex, synchronous communication bus with a master-slave structure, occupying only four lines on the chip pins, saving pin space and providing convenience for PCB layout. Due to … Read more
👇Click to follow for daily technical insights!👇 1 Introduction SPI: Serial Peripheral Interface, a serial peripheral interface. SPI was developed by Motorola around 1985 and is a synchronous serial interface suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors … Read more
Hello everyone, I am Daji Zong, and today I will talk about two commonly used communication buses on microcontrollers: SPI and I2C. As the names suggest, SPI stands for Serial Peripheral Interface, while I2C stands for Inter-Integrated Circuit Bus. Both are common methods for chip-to-chip communication. Introduction to SPI The SPI bus consists of four … Read more
A pull-up resistor connects a signal line to a fixed high level VCC, keeping the signal line in a high state when idle, which is known as a pull-up resistor. The pull-up resistors on a bus have different roles; for example, the pull-up resistors for I2C are determined by the internal structure of the I2C … Read more
Theme of This Issue With the rapid development of LLMs and their demonstrated application potential in various fields, research on LLM-based agents has garnered widespread attention from scholars. However, single-agent systems often exhibit drawbacks such as lengthy context and poor interpretability in reasoning processes in complex task scenarios. Meanwhile, research on multi-agent systems has recently … Read more
