The LP5890EVM can be powered either by the
TMS320F280039C LaunchPad with the USB power (when the current consumption is low) or an
external power supply (the LP5890EVM and the TMS320F280039C LaunchPad are powered
separately). Single LP5890EVM can be quickly set up and tested by following these steps:
- USB power supply from the TMS320F280039C
LaunchPad
- Download the code to the
TMS320F280039C LaunchPad with TI Code Composer Studio software.
- Put the J6 jumper on "MCU5V" and the
middle, and set the switch S1 towards "SOUTHOST" , which are marked with red boxes in
Figure 2-3.
- Connect BoosterPack connectors (J1,
J2) on the LP5890EVM with the TMS320F280039C LaunchPad, the connection method is shown
in Figure 2-3.
- Power the TMS320F280039C LaunchPad
through the USB cable.
- External power supply
- Download the code to the
TMS320F280039C LaunchPad with TI Code Composer Studio software.
- Put the J5 jumper on "TP1 5V" and "EX
5V". Then put the J6 jumper on "EX5V" and the middle. Set the switch S1 towards
"SOUTHOST".
- Connect BoosterPack connectors (J1,
J2) on the LP5890EVM with the TMS320F280039C LaunchPad, the connection method is shown
in Figure 2-3.
- Power the TMS320F280039C LaunchPad
through the USB cable.
- Connect TP1 and TP2 to 5V/GND power
source.
- Power on 5V/GND power supply.
