4.3 LED Lights

There are LED indicators on both the LAUNCHXL-F280049C and DRV8329AEVM when power is provided and the micro USB cable is plugged in to the LaunchPad.

The DRV8329AEVM has 4 status LEDs on the board. By default, the PVDD and AVDD LEDs will light up when the board is powered on. The fault LED will light up when the driver reports a fault, and the MCU LED (tied to GPIO59) can be used for debugging and validation. Table 4-1 shows the LED descriptions, with the LEDs that are on during power up indicated in bold. Figure 4-5 shows the LED locations on the EVM. These LEDs all have removable jumpers to reduce power consumed by the EVM.
