Module Introduction The SPI Bus System is a kind of Synchronous Serial Peripheral Interface, it can make the MCU communicate with the different peripheral devices by the Serial Mode to exchange information. The SPI Bus System can start Data Transmission with a lot of standardized peripheral implements of the different manufacturers. There are three signal channels for the Protocol Analyzer SPI in general, which are the CS, SCK and SDA. The CS can be set as High Level or Low Level in effect, the Data Transmission is happened at the Rising Edge or Falling Edge of the SCK. Application Field It is applied in the aspect of Data Communication, such as FLASHRAM, Network Controller, LCD Display Driver, A/D Converter, MCU and so on. 【DOWNLOAD】
