Hello everyone, in this article we will talk about a common communication protocol in embedded development – the SPI protocol. However, today we will not discuss its basic principles, but rather explore a detail that many may not have noticed: the 4-wire and 7-wire versions of the SPI protocol. You might wonder, isn’t SPI just … Read more
# Click the blue text to follow us and never miss exciting content Origin of SPI The SPI interface was first proposed by Motorola (now NXP) for high-speed data transfer between processors and peripheral devices. Due to its simplicity, efficiency, and low resource consumption, it quickly gained widespread adoption and became one of the most … Read more
Introduction The previous article detailed the SPI module under the Autosar architecture diagram, but did not cover the SPI communication bus. This article is a repost of what I consider to be a well-written introduction to the SPI communication protocol for your reference.
