Adafruit nRF52840 Feather support

[Avamander]

I read on the forums and from the documentation that the nRF5 series are supported to some extent. I am wondering what does it actually take to get the gateway sketch running on the device?

Right now it didn't even detect the board properly so I had to help it a bit - I changed Flash.h to load the NRF5 HAL and nRF52840 flash parameters.

But now it's just erroring out further:

I don't think the nRf52840 supports 250KPS speed, so you need to set to 1Mbit and also remove reference to the 250KBPS in the enumeration definition in Radio.h and reference in Radio_ESB.cpp. Also the definition for pins is only up to 32 pins i.e. P0.0-P0.31. adafruit also uses connector P1.0-P1.31. So the pin definitions in MySensors would need updated to cover up to 64 pins i.e. pin references 0-63. I put a post about this here in MySensors forum

Not sure, it might not if the references remain (even if not used).

I'd love to have it working, but I don't know how exactly.
