From AVRFreaks Wiki

Jump to: navigation, search

Serial Peripheral Interface (SPI) is used for generic serial communication between AVR32 processors and peripherals.

The SPI is used to configure both the external DAC and the LCD screen. In addition the interface is routed to the dedicated SPI header, the general expansion headers and the PCI style expansion connector.

Peripherals and connectors

  • External DAC (1)
  • LCD screen (2)
  • PCI style expansion connector (3)
  • General expansion headers (4)
  • SPI header (5)

Signals

Please refer the datasheet for the AVR32 processor on you daughter board for a description of these signals
