[En-Nut-Discussion] using SPI Controller of AT91SAM7X

[Dominik Schröder]

Hello

 

I want to use the SPI controller of my AT91SAM7X to communicate with an OLED
Display. I haven’t found some good information about which steps are needed
to get the SPI device working
 L

I know that I have to write something like this:

 

NUTSPINODE OLED_node = { &spiBus0At91, NULL, 150000, 0, 8, 1 };

 

But how can I write some DATA to the SPI BUS?

Can anybody give me an example?

 

Best regards!
