20m WSPR Beacon
Below is the software. Looks like the formatting has been affected when it was copied over. Auto format in the Arduino IDE works great!

Hello Charlie, i can't compile this :-(
ReplyDeleteWhere did you download the library:
#include
thanks Daniel/Germany
Ohh the software cuts the Library name :-(
ReplyDeleteThe name is: DDS.h
Hi David. This was in the README file for the DDS library:
ReplyDeleteDDS : A Library to host an AD9850 DDS Module on Arduino, using soft SPI
This is a library which controls the widely available,
low-cost Direct Digital Synthesis ('DDS') Modules,
based on the Analog Devices 9850 chip
on the Arduino.
For more information:
http://m0xpd.blogspot.co.uk/2014/03/dds-and-duedds-libraries.html
Four IO lines are required to connect to the AD9850 module...
(W_CLK, FQ_UD, DATA & RESET).
To download and use this Library, click the Download ZIP button (on the RHS of this screen).
Uncompressed the downloaded ZIP archive and rename the folder DDS.
Put this DDS folder in you Arduino Libraries folder and restart the Arduino IDE.
To control multiple DDS Modules, see here:
http://m0xpd.blogspot.co.uk/2015/06/handling-two-dds-modules-in-library.html
Thank you Charlie, now i can compile the sketch :-)
ReplyDeleteWill set up the LEDs and the AD module.
I like the Si5351 more, its only half the size and 2 ports A4/A5
Great videos and a lot of calculations on your papers for all the resistors..etc!
That's great. Glad to hear!
