3.1.1.4 LEDs

Power indicator LEDs (red) are included on the F29H85x LaunchPad board. Table 3-3 shows descriptions of each LED.

Table 3-3 Power LED Indication Descriptions
LED NumberIndication Description
LED1+5V power from the USB Type-C™ connector
LED7+3.3V power on the XDS110 side of the PCB
LED3+5V power on the F29H85x 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 GPIO19 and GPIO62 of the F29H850TU, 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 NumberDescription
LED4Active-low user-configurable LED controlled by GPIO19
LED5Active-low user-configurable LED controlled by GPIO62

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 NumberIndication Description
LED8Indicates that the XDS110 device is actively connected to a debugger target session (for example, CCS IDE debug session)
LED9Indicates that the XDS110 device is powered and functional
