I am Lao Wen, an embedded engineer who loves learning.Follow me to become even better together! In communication design, considering the flexibility of protocols, they are often designed to be “variable length”. An example is shown in the figure below: the communication protocol frame of the Ruimi LoRa terminal. If a system receives the above … Read more
Why I²C is one of the most commonly used communication protocols in embedded systems?1. Background and Importance of I²C Communication The I²C (Inter-Integrated Circuit) communication protocol was developed in the 1980s by Philips (now NXP Semiconductors) to simplify communication between various integrated circuits within electronic devices. It is particularly suitable for scenarios requiring low-speed interconnection … Read more
Insights on AHB Bus Learning The AMBA 3 AHB-Lite protocol is designed for high-performance synthesizable designs, supporting a single bus master and providing high bandwidth operations. It features burst transfers, single clock edge operations, non-tristate implementations, and configurable data bus widths from 64 bits to 1024 bits, making it suitable for connecting internal storage devices, … Read more
1. IntroductionSPI (Serial Peripheral Interface) is a high-speed, full-duplex synchronousserial communication bus protocol developed by Motorola, operating in a master-slave mode, enabling data transmission between devices through four lines (SCLK, MOSI, MISO, CS). Its core features are:① Full-duplex communication: Data can be transmitted in both directions simultaneously, allowing both the master and slave devices to … Read more
