3.1.3 LEDs

Power indicator LEDs (red) are included on the F28P65x LaunchPad board. Table 3-3 shows descriptions of each LED.

Table 3-3 Power LED Indication Descriptions
LED Number Indication Description
LED1 +5-V power from the USB Type-C™ connector
LED7 +3.3-V power on the XDS110 side of the PCB
LED3 +5-V power on the F28P65x side of the PCB
LED6 +3.3-V power on the F28P65x side of the PCB

Two user LEDs are provided on the board: LED4 (red) and LED5 (green), see Table 3-4. These user LEDs are connected to GPIO12 and GPIO13 of the F28P650DK9, 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 the LED. These LEDs are dedicated for use by the software application.

Table 3-4 User-Configurable LED Descriptions
LED Number Description
LED4 Active-low user-configurable LED controlled by GPIO12
LED5 Active-low user-configurable LED controlled by GPIO13

Two blue LEDs, LED8 and LED9, are connected to the XDS110 debug probe, see Table 3-5. These indicate debugger activity and are not controllable by any application software.

Table 3-5 XDS110 LED Descriptions
LED Number Indication Description
LED8 Indicates that the XDS110 device is actively connected to a debugger target session (for example, CCS IDE debug session)
LED9 Indicates that the XDS110 device is powered and functional

To properly conform with the EtherCAT protocol, the F28P65x LaunchPad comes equipped with a number of LEDs that indicate activity for EtherCAT communication. In addition to the PHY link status and link active LEDs, Table 3-6 lists the LEDs included on the board.

Table 3-6 EtherCAT Communication LED Descriptions
LED Number Indication Description
D11 Controlled by GPIO33, EtherCAT run LED (green)
D12 Controlled by GPIO61, EtherCAT error LED (red)
