SPI Bus

[BluesBilly]

Can you overload init() function? You can specify which SPI bus to use.

void EthernetClass::init(uint8_t sspin)
{
W5100.setSS(sspin);
}

void EthernetClass::init(uint8_t sspin, SPIClass &spi)
{
_spi = spi;
W5100.setSS(sspin);
}

Can you make a Pull Request? .init is reserved it should changed to .setSPI

[sstaub]

For change the CS pin there is Ethernet.setCsPin(3); // set Pin 3 for CS

Indeed, setspi is more reasonable. You need to add the function of setspi instead of using global SPI.
