There are 2 SPI interface firmware modules, the buffered SPI interface and the simple SPI interface, For your application, I would be tempted to use the simple SPI interface and talk to its registers directly with a comp > ------------------------------------------------------------------------------ > Learn Graph Databases - Download FREE O'Reilly Book > "Graph Databases" is the definitive new guide to graph databases and their > applications.
