Run with any SPI port on boards with multiple SPI #134

Open KooLru opened 4 years ago

KooLru commented 4 years ago

For use another than defined SPI "port", you need:

  1. Declare an SPI class object with appropriate pins

SPIClass SPI_2(PB15, PB14, PB13);

I have try SPI2 on STM32F103xB also known as "Blue pill"

  1. Call Ethernet.init()

Ethernet.init(SPI_2, PB12);

  1. Profit!

I also add this line in DhcpAddressPrinter sample, and define for Serial port, for debug on boards with more than one UART

@KooLru nice! Needed this and it works as described!

do I need this patch too, if I only want change the pins of spi-1? I want at the maple mini use the w5500 lan module at the pins of spi-2 this does not work:

SPIClass SPI_1(28, 29, 30);  // SPI2 pins
Ethernet.init(31);
Ethernet.begin(mac);  // DHCP
