SPI1INIT, SPI1IN, SPI1OUT, SPI1MOVE

Some of the new MEGA processors like ATMEGA328PB have a second SPI bus. This is not a USART that can work in SPI mode but a full SPI bus.

 

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

 

CONFIG SPI1

SPI1INIT

SPI1IN

SPI1OUT

SPI1MOVE

 

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