I have the same problem with my R4 UNO and I got a reply to my ticket saying that this library is only good for Atmel microcontrollers. My R4 did NOT have that microcontroller, so maybe yours too? I have ordered a new UNO R3 which I will test tonight or tomorrow and will try to report back. I also ordered and received another DMX shield which did the same thing. My R4 works fine otherwise, but even with the most basic code that blinks the onboard LED, when I install the shield, whether enabled or...

Hi, ok thanks. it seems the R4 uses a RA4M1 controller. Mind offering any tips for how to find this? I bought this hardware (including a DMX shield) which listed all sorts of compatibility and nowhere did anything mention anything about needing specified controllers. Abysmal docs; kind of typical. But, not being an engineer, I'm a little bit lost now. Thanks!
