Hi all
I am currently working with the LP5562 LED driver EVM.
I am having problems with the LEDs lighting up via the GUI.
I think my settings are OK and the board is connected correctly. I know how to load the sequences into SRAM via the program tab, but I can't get them to light up...
Can anyone help me? What am i doing wrong?

Thank You already now!!!

Hi Florian,

Can you please check if you can light the LED in manual mode first?

Hi Jared Thanks for your response! I couldn't get the LEDs to work in manual mode either... maybe I'm doing something wrong? Can you briefly explain to me how this works?

Thank you very much!!

Greetings from Switzerland!

Hi Florian,

I think you should set the clock as internal clock if you don't have any other clock input.

Hey Jared
Thanks for the tipp, i have no external clock... I have looked at it again with my supervisor on his PC and we went trough the whole instruction manual... He has some more experience... it works now. To be honest, The GUI is not very clever...

Thank you and have a nice day!!
