SAMD21 (Arduino Zero) Support #155

Open ljbeng opened 8 years ago

Will this library be compatible with the SAMD21 any time soon?

Ethercard uses direct Register access on the AVR, which won't work on ARM.

a simple ( or simplistic ) way of looking at it is to make sure reads, writes and chipselects are changed to use the SPI library instead of direct register usage ( which is specific to AVR only in this case ).

The SPI interface will have to be rewritten/replaced by the Arduino SPI library's interace things likeSPDR = *data++; can be replaced by SPI.transfer(*data++); for example.

I did get UIPEthernet working on SAMD21E16, but I started with https://github.com/UIPEthernet/UIPEthernet. Found all defines for ARCH_SAM and added checks for ARCH_SAMD next to them. So far testing for few days and looks OK-ish. There are glitches but they may be unrelated.
