Some of the new MEGA processors like ATMEGA328<span style="font-weight: bold;">PB</span> have a second SPI bus. This is not a USART that can work in SPI mode but a full SPI bus.

&nbsp;

In order to use the second SPI which is named SPI1, you have to add a '1' to the SPI commands&nbsp;:

&nbsp;

[[CONFIG SPI|CONFIG SPI1]]

[[SPIINIT|SPI1INIT]]

[[SPIIN|SPI1IN]]

[[SPIOUT|SPI1OUT]]

[[SPIMOVE|SPI1MOVE]]

&nbsp;

The statements above link to the description of the SPI statements (SPI0).
