Dear Kristin and Clancy,

Why is it LED still at red light though it already connected to GUI?

Hi Janine,

This thread explains the functions of the LEDs: e2e.ti.com/.../700086

Are you saying that only your red LDC turns on when the GUI shows that the EVM is connected?

Best Regards,

Are you able to read registers on the register page of the GUI? What does the Device_ID register show?

Dear Kristin,

I noticed that if i only used 1 channel when its connected to GUI, LED green will light.
But, If i used 3 channels when its connected to GUI, LED red will light. Why?

Green or red light, still have a variation.

Hi Janine,

If you are able to read and write to the registers and stream data from the GUI, I would not worry about what the LEDs are doing. They are not a critical part of the EVM's functionality.
