Hi Phil,
A colleague has already responded to your query via support. To ensure we have all the information, I’m adding some additional questions here on the forum as well. We need more details from you:
Has the problem been present since the beginning, or did something change?
What has changed? Did the LEDs work well before?
What REXYGEN project are you using? Can you try running the "0121-09 Monarco HAT Demo Example" and see if you can trigger the LEDs?
What does the system log say?
Best regards,
Jan
