The sample code showcases the ability to light up the LEDs on the TLC69628Q1EVM. There are no modifications needed by the user to be able to light up the EVM.

There are two modes in the code: animation and simple test. The animation mode is selected by default. Section 3.3 describes how to change between the modes. In the animation mode, one frame is used to scroll left, right, up, and down and to fade in and fade out according to a predefined sequence. The frame is a Texas Instruments logo of 99x6 pixels. This means that not always the full frame is shown on the LED display of the EVM. Examples of this can be seen in Section 3.6. The method how to generate the frame in the sample code is outside the scope of this document.

In the simple test mode, the user can use some predefined APIs to light up the LED board, perform diagnostics, or build custom interface commands. The sample code comes with turning on all LEDs using a 50% duty cycle. In addition, diagnostics is executed to determine any LED and LED driver faults. For more information about diagnostics see Section 3.5. The predefined APIs automatically adjust to the specified system. More detail about the system specification can be found in Section 3.3 and Section 3.4.
