#24 Arduino not running with shield attached
I have an Arduino R4 wifi - brand new. Tested and it seems fine. I have now ordered my 2nd DMX Shield MAX485 to rule out it being faulty and I get the same exact results.
I can't send sketches to it no matter what unless it is OFF the board.
Setting the jumper to enable/disable does nothing.
Not only can I not push sketches to it when the shield is onboard, but no sketches even run. Even those that just blink the onboard LED. I have the most basic sketch that just blinks the onboard LED, and that will not run if the shield is attached.
I'm definitely a newb, so maybe there is a requirement to have some preamble if the shield is attached, but I can find nothing about that in hardware.
Any ideas?
Am I in the right place for help? lol
Thanks!
The libraries are for Atmel based chips. If your Arduino uses a different controller then you should find a different library.
Kind Regards

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!
