Understanding Various Buses: A Comprehensive Guide to SPI, I2C, UART, I2S, GPIO, CAN, and SDIO

Buses, buses, they always get you tangled up. In this world, signals may be the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. Internal buses are used for interconnections between peripheral chips and processors within … Read more

SPI, AOI, and X-Ray: The Triple Guardians of SMT Production

SPI, AOI, and X-Ray: The Triple Guardians of SMT Production

In the SMT (Surface Mount Technology) production line, the birth of each circuit board is a game of precision and efficiency. From solder paste printing to component placement, and then to soldering and curing, even the slightest flaw in any link can trigger a “butterfly effect”—leading to unstable product performance at best, or mass rework … Read more

Design Challenges of Electromagnetic Compatibility (EMC) in High-Speed DSP Systems

Design Challenges of Electromagnetic Compatibility (EMC) in High-Speed DSP Systems

With the increasing popularity of high-speed Digital Signal Processors (DSPs) and their peripherals, electronic system designers are facing increasingly severe issues related to electromagnetic interference (EMI). In earlier studies, such issues were often referred to as electromagnetic interference (EMI) or radio frequency interference (RFI), while modern engineering more accurately adopts the concept of “electromagnetic compatibility … Read more
