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).

 

  

'in this demo we only use the second SPI interface
Config Spi1 = Hard , Interrupt = Off , Data_order = Msb , Master = Yes , Polarity = Low , Phase = 0 , Clockrate = 128
 
'second SPI
Spi1init
B = 5
Spi1out A(1) , B
Spi1in A(1) , B
A(1) = Spi1move(a(2))
