Step 2: All white LEDs of TLC6C5748EVM board will be on and LED2 is on with green color if there are no problems. Otherwise, The LED1 and LED2 shown in Figure 2-9 will be on with red, blue or purple color to indicate the specific fault. The control signals of TLC6C5748-Q1 and the meanings of different status of LED1 and LED2 are summarized in Table 3-1. The number of LED short and LED open fault can be read back respectively through expressions in CCS along with the location of fault pins. Please refer to the concrete steps for adding watching expressions in CCS IDE. The meaning of fault data can be found from the comments in User_Param_Config.h file in the project of the sample code.

Step 3: Press S1 of MSP-EXP432P401 Launchpad shown in Figure 2-9 will switch the brightness of all The LEDs.

Step 4: Turn off the power supply and disconnect the MSP-EXP432P401 Launchpad from the PC. Then disconnect the MSP-EXP432P401 Launchpad from the TLC6C5748EVM.
