• Put ashunt on J53 to connect the USB2ANY 3.3-V supply to VCC. In this case, extra DC supply is not needed to supply the VCC.

• Connect the host computer to the USB2ANY board via a USB cable. xx

• Connect the ribbon cable between the USB2ANY board and the TLC6C5716-Q1 EVM board.

2.2 Software Installation

Download the GUI software from the TLC6C5716-Q1 EVM tool folder and install on the PC. Once installed, a shortcut to the GUI is found on the desktop and also in the start-up menu under the Texas Instruments folder. Figure 3 shows the landing page of the TLC6C5716EVM GUI.

2.3 GUI Function

This section provides instructions to run the TLC6C5716EVM using the TLC6C5716EVM GUI.

2.3.1 Connection Status

The TLC6C5716EVM connection status appears on the GUI landing page. A red status indicator means Device Not connected, a green status indicator means Device connected. Click the Go Advanced button and a quick configuration page opens for control of the TLC6C5716EVM.

2.3.2 Advanced Settings Page

The Advanced Settings page (Figure 5) provides more register configuration features. The GLOBAL RESET button resets the TLC6C5716-Q1 internal registers, meaning all registers values are set to 0, except the Mask LED Error bit is set to 1. The INITIALIZE ALL CH VALUES buttons turns on all channels with 50% grayscale (GS), dot correction, and brightness control values. GS and dot correction channels can be adjusted separately.

For APS TEST and LOD TEST, turn off all output channels first, then perform the test. For other configurations, refer to TLC6C5716-Q1 16-Channel, Full Diagnostics, Constant-Current LED Driver With 7-Bit Dot Correction and 12-Bit PWM Dimming for details.
