2.1.1.2 LEDs

Power indicator LEDs (red) are included on the F28P55x LaunchPad board. Table 3-2 shows descriptions of each LED.

Table 2-2 Power LED Indication Descriptions
LED NO.Indication Decription:
LED7+5 V power from the USB Type-C connector
LED0+3.3 V power on the XDS110 side of the PCB
LED1+3.3 V power on the F28P55x side of the PCB
LED6+5 V power on the F28P55x side of the PCB

Two user LEDs are provided on the board: LED4 (red) and LED5 (green). These user LEDs are connected to GPIO20 and GPIO21 of the F28P55X, respectively. The signals 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 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.
