4.1 Test Setup

The typical parameters for TLC6984 EVM are shown in Table 4-1.

Table 4-1 TLC6984EVM Parameters
Parameter Value
VCC device supply voltage 2.5–5.5 V
VLEDR/G/B supply voltage 2.5–5.5 V
ICH constant output source current 0.2–20 mA

The TLC6984EVM can be setup and tested by following these steps:

  1. USB power supply
    1. Download the code to TMS320F280039C LaunchPad with TI Code Composer Studio software.
    2. Connect boosterpack connectors (J1, J2 on EVM board) with the TMS320F280039C LaunchPad. The connection method is shown in Figure 4-1.
    3. Disconnect J4 jumpers (5V/ 3V3) block, connect J5 jumper, and connect J3 with the mini-USB cable (the same cable with the TMS320F280039C LaunchPad).
  2. External power supply
    1. Download the code to TMS320F280039C LaunchPad with TI Code Composer Studio software.
    2. Connect boosterpack connectors (J1, J2 on EVM board) with the TMS320F280039C LaunchPad. The connection method is shown in Figure 4-1.
    3. Disconnect J4 jumpers (5V/ 3V3), connect J5 jumper, and connect TP1/TP2 to 5V/GND power source.
    4. Power on 5V/GND power supply.
