Datasheet

The firmware is a working example of how to initiate the system and wait for a user's input. A user can select
the output mode and type in the DAC input codes. The simple process flow is shown in Figure 2. The
firmware is written in C using the Xilinx software development kit (SDK) tool, which is based on the
EclipseTM open source standard. Custom Alameda-specific design functions were created utilizing the
standard Xilinx XSpi core version 3.03a. The SPI clock frequency is set to 2MHz on the LX9 platform and
3.125MHz on the ZedBoard platform.

The complete source code is provided to speed up customer development. Code documentation can be
found with the corresponding firmware platform files.
