Re: problem while trying leds access example

Hello @sahithigurram25

Out of multiple example givens in the link which exact example are you trying to run ?

Can you check cross check jumpers power, power supply and switch settings and if there is any GPIO used switch used in the design to reset the LEDs ?

Thank you
