Part Number: FDC2114EVM


Hi

I have simple question.

There is Green LED and Red LED on EVM. What is that for?

On the app note , there is no explanations.

The each LED may be shown some condition. For example ,I would like to know the status when Red LED lights on.(green LED as well)

Best Regards,
Koji Hamamoto

    Hi Koji,

    The LEDs follow the following pattern after the device is plugged in and powered on:

    1. The Red LED turns on to show that configuration has begun.
    2. Both Green and Red LEDs turn on to show the EVM is ready.
    3. If the GUI is streaming data, both LEDs will turn off to show data is being read. The Green LED will turn on to show the cycle has been
    completed.
    4. If the EVM is no longer connected, the Green LED will turn off and the Red LED will turn on.
    5. If something is wrong with the I2C communication, the Red LED will blink every 100 milliseconds.
