SPI Protocol Analyzer

The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification
used for short-distance communication, primarily in embedded systems. There are four SPI inter-
face signals: MISO (Master Input Slave Output), MOSI (Master Output Slave Input), SCK (Serial
Clock), CS/SS (Chip Select or Slave Select). Information is transferred between Master and Slave on
defined clock edge when CS/SS is in active state (if CS/SS is used). Active state of Chip Select
(LOW or HIGH) is configurable.
Using digital inputs, optional SPI protocol analyzer is available for easy monitoring of two SPI in-
terfaces within the Embedded system either alone or in conjunction with the program execution.
SPI protocol analyzer modules (SPI1, SPI2) are by default disabled because they consume digital
I/O connectors or BANKS as specified in winIDEA. Note that if SPI1 is enabled it consumes DIO
BANK0, and if SPI2 is enabled it consumes DIO BANK2.
To configure the SP1 and/or SP2 open Hardware menu / Options / FNet tab and double-click FNode
ADIO to open the ADIO configuration dialog.
1. Open SPI1 tab (or SPI2 tab) and enable SPI.
2. Click Network and give it a meaningful name which is shown in the Analyzer window.
3. Add SPI description files (*.spi). Find TASKING SPI protocol description format in winIDEA Help.
4. Chip Select is required. Click Edit and select CS0, CS1 or CS2.
NOTE: Make sure physical SPI signals are connected according to the Pin mapping on DIO BANK0
(or DIO BANK2).
