This project contains module designs and arduino sketches
for a simple power meter (based on the LTC5564) and an
inexpensive DDS frequency synthesizer (100kHz to about 40MHz).

Code for the modules is in

AD9850_Synth: the synthesizer -- requires an arduino, an LCD Button Shield,
and an AD9850 module installed on the RF shield.

LTC5564_Meter: the power meter -- requires an arduino, an LCD button shield,
and a power meter installed on the RF shield.

module:

The shield module is in the "module" directory which contains EAGLE
files for an Arduino shield that can hold either an LTC5564 power
detector, or a DDS synthesizer module based on the AD9850.  (This is
the popular and very cheap module available on the web, at
Banggood.com, Ebay, and others.)

The 5564 output is routed to Analog input A1.  The G0 and G1
controls are connected to D2 and D3, respectively.  This keeps
the pin assignments out of the way of the 16x2 LCD button shield
(Sparkfun DEV-13293.)

The AD9850 is connected to avoid the LCD as well.
