The TLC6983EVM can be setup and tested by following steps,

  1. USB Power supply
    1. Download the code to MSP430F5529 LaunchPadTM with TI CCS software.
    2. Connect boosterpack connectors (J1, J2 on EVM board) with the MSP430F5529 LaunchPadTM, the connection method is shown as below figure.
    3. Disconnect J4 jumpers(5V/ 3V3) block and connect J3 with the mini-USB cable (the same cable with the MSP430F5529 LaunchPadTM ).
  2. External Power supply
    1. Download the code to MSP430F5529 LaunchPadTM with TI CCS software.
    2. Connect boosterpack connectors (J1, J2 on EVM board) with the MSP430F5529 LaunchPadTM, the connection method is shown in Figure 3-1.
    3. Disconnect J4 jumpers(5V/ 3V3) and connect TP1 and TP2 to 5V/GND power source.
    4. Power on 5V/GND power supply.

      Figure 3-2 shows the hardware setup of the TLC6983 by using USB Power.
