2.1.2 LEDs

Two power indicator LEDs are included on the board: LED0 indicates when the 3.3 V is available on the USB side of the isolation barrier and LED1 indicates when 3.3 V is available on the device side of the isolation. LED1 indicates that there is power supplied to the F28004x device as well as the XDS110 debugger.

Two user LEDs are provided on the board: LED4 (red) and LED5 (green). These user LEDs are connected to GPIO23 and GPIO34, respectively. These are connected to the SN74LVC2G07DBVR LED driver IC and are connected in an active low configuration; that is, drive the GPIO low to turn on the LED and high to turn it off. These LEDs are dedicated for use by the software application.

Two blue LEDs, LED2 and LED3, are connected to the XDS110 debug probe. These indicate debugger activity and are not controllable by any application software.
