Finding common SPI error

Keywords:interface  failure  microprocessors 

How can an interface turn a happy face to a sad face? Engineers have happy faces when an interface works properly. Sad faces indicate failure somewhere. Because interfaces between microprocessors and ICs are simple—even easy—they are often ignored until interface failure causes sad faces all around. In this article, we discuss a common SPI error that can be almost impossible to find in a large system. Noise as a system issue and ICs to minimise its effects are also described.
