Launching the demo application requires 3L‟s Diamond software suite to be
installed, at the very least the Server.
The demo is designed to be run using the SMT148-FX carrier board, with an SMT362
on TIM site 1 and an SMT351T-SX50 + SMT911 on TIM site 4. The comport
configuration for this SMT148-FX setup is the „default anti-clockwise‟. The latest
SMT6048 needs to be installed to connect to the SMT148-FX, and the SMT6002 will
be needed if the comport configuration of the carrier needs to be changed. If
„default clockwise‟ is instead loaded on the carrier, then the SMT351T-SX50 +
SMT911 can be alternately moved to TIM site 2, keeping the SMT362 in the same
position. (only T1C0 – T4C3 is used)
The „SMT911_Control.ngc‟ provides a ready to use interface for configuring the
registers of the mezzanine and switching between various states. This should not
need any modification when developing custom tasks, although new tasks or the
„Data‟ task can be modified any number of ways to create custom hardware
processing.
In the DSP task is an array called „BlockofRegisters[]‟ which has all the default
register configuration settings loaded at start-up. Details on the registers and the
structure for writing to specific fields can be found in the appendix. The datasheets
for the AD9863 and the MAXIM 2829 will offer further detailed information on what
each setting in these registers will do, and the format for writing to these registers
can be found in the header file for this task.
The applications depend on a couple folders being available, so these must be set
up first. On the „C‟ drive, make a new folder called „SMT911 Data‟, and in this folder
create a folder called „Received Data‟. The resulting path should be:
C:\SMT911 Data\Received Data\
Take the provided „SINE.dat‟ file and place it within the „SMT911 Data‟ folder. This is
the sample data file which the DSP will look for when loading the DDR memory for
transmit.
For both demo‟s, leave the jumpers off of the mezzanine to choose the onboard
crystal as the clock source, otherwise a larger system can be synchronized using an
external clock.
