2 Connectors
There are two connectors on the High-Speed SPI Flash Demonstration Board. These connectors can be used connect up to two devices. For example, a Cheetah SPI Host Adapter can be connected to the board to interface with the SPI Flash Memory and a Beagle I2C/SPI Protocol Analzyer can also be attached to monitor the bus.
These two connectors are connected together pin-for-pin with the exception of SS2 (Pin 1) and SS3 (Pin 3).
2.1 Powering the Activity Board
To power the High-Speed SPI Flash Demonstration Board, the Cheetah or Aardvark adapter must be configured to send target power to the board. This can be accomplished via the Rosetta Language Bindings, the Aardvark Control Center Software or the Cheetah GUI Software. When powered-on, the board's POWER LED will be lit.
2.2 Cross Connecting Aardvark and Cheetah Adapters
When cross connecting two adapters, the board must be powered on. Otherwise, results may be unpredictable. If you experience problems, please make sure that the Power LED on the board is lit.
3 Examples
Sample C code for the Cheetah SPI Host Adapter can be freely downloaded from the Total Phase website. While not all the examples will work with the High-Speed SPI Flash Demonstration Board, the flash.c example code was specifically developed against this target. The examples package include a README.txt file with instructions on how to compile the examples.
