Comprehensive Comparison of Communication Protocols IIC and SPI

In today’s low-end digital communication applications, we frequently encounter IIC (Inter-Integrated Circuit) and SPI (Serial Peripheral Interface). The reason is that these two communication protocols are very suitable for short-distance, low-speed communication between chips. Philips (for IIC) and Motorola (for SPI) developed these two standard communication protocols based on different backgrounds and market needs. IIC … Read more

Key Concepts of SPI in AUTOSAR for Automotive Embedded Development

In AUTOSAR, the SPI module actually divides one SPI communication into many small segments for organization and management. This approach allows for flexible control and easy expansion. Thus, we introduce the following three levels:Channel → Job → Sequence. 1. Channel 👉 Channel is the smallest unit, which can be understood as **”a block of data … Read more
