4.7 Step 6: Test the CLB Logic

This section discusses the instructions on how to test the Code Composer Studio™ example project provided for the LED driver example. The example is tested on the F280039C LaunchPad (LAUNCHXL-F280039C).

For test purposes, one LP5891-Q1 EVM is used to receive and display the image data from the F280039C MCU. The LP5891-Q1 EVM includes a 16x16 matrix LED display.
