5.8.3 LED Signals

eZ-FET emulators show their operating states using two LEDs, one green and one red. Table 16 lists all available operation modes. The eZ-FET 2.0 has an additional yellow LDO LED, that illuminates when the LaunchPad is connected to a computer.

An msp-fet_led_green_off_slau278.gif, msp-fet_led_red_off_slau278.gif, or msp-fet-led-yellow-off.gif icon indicates that the LED is off, an msp-fet_led_green_on_slau278.gif, msp-fet_led_red_on_slau278.gif, or msp-fet-led-yellow-on.gif icon indicates that the LED is on, and an msp-fet_led_green_blink_slau278.gif or msp-fet_led_red_blink_slau278.gif icon indicates that the LED flashes.

Power LED Mode LED LDO LED
(eZ-FET 2.0 Only)		 Function
msp-fet_led_green_off_slau278.gif msp-fet_led_red_off_slau278.gif – eZ-FET not connected to PC, or eZ-FET not ready; for example, after a major firmware update. Connect or reconnect eZ-FET to PC.
msp-fet_led_green_on_slau278.gif msp-fet_led_red_off_slau278.gif – eZ-FET connected and ready
msp-fet_led_green_on_slau278.gif msp-fet_led_red_on_slau278.gif – eZ-FET waiting for data transfer
msp-fet_led_green_on_slau278.gif msp-fet_led_red_blink_slau278.gif – Ongoing data transfer – during active debug session
msp-fet_led_green_off_slau278.gif msp-fet_led_red_on_slau278.gif – An error has occurred; for example, target VCC over current. Unplug eZ-FET from target, and cycle the power off and on. Check target connection, and reconnect eZ-FET.
msp-fet_led_green_blink_slau278.gif msp-fet_led_red_blink_slau278.gif – Firmware update in progress. Do not disconnect eZ-FET while both LEDs are blinking.
– – msp-fet-led-yellow-on.gif The LDO target supply is active (the LDO is the default supply).
– – msp-fet-led-yellow-off.gif The EnergyTrace power supply is active.
