use of SPI2 on SPI- or Ethernet lib

[Ralf9]

Hi,

is there a possibility to use on Maple Mini SPI2 on the SPI- or Ethernet library?

I don't find any way at the SPI- or Ethernet library, how I can specify that I want use SPI2

Thank you

With this it works with the pins of SPI2

Code: Select all

	#define csPin	31
	#define mosiPin 28   // MOSI out
	#define misoPin 29   // MISO in
	#define sckPin  30   // SCLK out
	
	SPI.setMISO(misoPin);
	SPI.setMOSI(mosiPin);
	SPI.setSCLK(sckPin);
	SPI.begin(); //Initialize the SPI port.
	SPI.setBitOrder(MSBFIRST);
	SPI.setDataMode(SPI_MODE0);
	SPI.setClockDivider(SPI_CLOCK_DIV16);      // Slow speed (72 / 4 = 4.5 MHz SPI speed)

When I try this

Code: Select all

	#include <SPI.h>
	SPIClass SPI2(mosiPin, misoPin, sckPin);

I become on the Arduino IDE the follow Errors

Code: Select all

I want use cc1101 Modules on SPI2 and a W5500 Lan Modul on SPI1


My sketch should work too on an existing hardware with the cc1101 Modules on SPI1 and the Lan Modul on SPI2.

Ist there a a possibility to use the W5500 Lan Modul on SPI2?

You couldn't call your SPI2 instance SPI2 because it is a CMSIS definition.
So call it SPI_2 for example.
