Software Setup ==== Download and extract the WaveForms workspace from the {{reference:test-and-measurement:analog-discovery-2:spi-protocol-viewer:spi-protocol-viewer.zip|SPI Protocol Viewer Workspace ZIP Archive}} (also linked in the inventory section, above). ---- <WRAP GROUP> <WRAP COLUMN HALF> Open WaveForms. Upon launch, WaveForms will generate a prompt asking to switch to the device used with the workspace. As this is the device originally used when the workspace was created and archived, select **No**. Navigate to //Settings -> Device Manager// in the menu bar at the top of the window, to check that the active device is your Discovery device. </WRAP> <WRAP COLUMN HALF> {{reference:test-and-measurement:digital-discovery:pmod-kypd-output-to-console:device-manager.png|}} </WRAP> </WRAP> ---- <WRAP GROUP> <WRAP COLUMN HALF> Click the **Open Workspace** button on the Welcome tab. Navigate to and open the //spi-protocol-viewer// workspace in WaveForms. </WRAP> <WRAP COLUMN HALF> {{reference:test-and-measurement:digital-discovery:spi-protocol-viewer:open-spi-protocol-viewer-workspace.png?600|}} </WRAP> </WRAP> ---- ==== 3. Running the SPI Protocol Viewer ==== The workspace is ready to use. Press the "Single" button in the Logic window, then press the **Execute** button in the //Protocol Analyzer// instrument. The //Logic Analyzer// will display the decimal values of the ASCII codes for "Hello World!". **Note:** //To view the data through the Logic Analyzer while using the Protocol Analyzer, the Protocol Analyzer was placed into debug mode, which disables the Protocol Analyzer's ability to receive data. If this workspace is used to receive data through the Protocol Analyzer, the debug button will need to be deselected.// ---- <WRAP GROUP> <WRAP COLUMN HALF> {{reference:test-and-measurement:analog-discovery-2:spi-protocol-viewer:shot2.png|}} <html><center></html>//Protocol Analyzer Instrument//<html><center></html> </WRAP> <WRAP COLUMN HALF> {{reference:test-and-measurement:analog-discovery-2:spi-protocol-viewer:shot1.png|}} <html><center></html>//Logic Analyzer Instrument//<html><center></html> </WRAP> </WRAP> ---- ===== Final Notes ===== This workspace is a good starting point for testing a SPI device through WaveForms. By simply modifying the contents of the ASCII array, different values can be sent to a SPI slave device. An additional SPI bus can be added in the Logic Analyzer to view a device's responses on the MISO data line.
