AD469X-FMC HDL project
|
||||
===============================================================================
|
||||
|
||||
Overview
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
The AD469X HDL reference design provides all the interfaces that are
|
||||
necessary to interact with the devices on the :adi:`EVAL-AD4696 <EVAL-AD4696>`
|
||||
board.
|
||||
|
||||
The design has a SPI Engine instance to control and acquire data from the
|
||||
:adi:`AD4696` 16-bit precisions ADC, providing support to capture continuous
|
||||
samples at maximum sampling rate. Currently the design supports the Zedboard.
|
||||
|
||||

|
||||
|
||||
Block design
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
The reference design uses the standard :ref:`SPI Engine Framework <spi_engine>`
|
||||
to interface the :adi:`AD4696` ADC in single SDO Mode. The :ref:`SPI Engine
|
||||
Offload module <spi_engine offload>`, which can be used to capture continuous
|
||||
data stream at maximum data rate, is triggered by the BUSY signal of the device.

Building the HDL project
|
||||
-------------------------------------------------------------------------------
|
||||
|
||||
The design is built upon ADI's generic HDL reference design framework.
|
||||
ADI does not distribute the bit/elf files of these projects so they must be
|
||||
built from the sources available :git-hdl:`here </>`. To get the source you must
|
||||
`clone <https://git-scm.com/book/en/v2/Git-Basics-Getting-a-Git-Repository>`__
|
||||
the HDL repository, and then build the project as follows:
|
||||
|
||||
**Linux/Cygwin/WSL**
|
||||
|
||||
.. code-block::
|
||||
:linenos:
|
||||
|
||||
user@analog:~$ cd hdl/projects/ad469x_fmc/zed
|
||||
user@analog:~/hdl/projects/ad469x_fmc/zed$ make
|
||||
|
||||
A more comprehensive build guide can be found in the :ref:`build_hdl` user guide.
