Im newbie. I buy AD as like at the picture. Im try to connect AD to my UNO: ***. Using digital pins 8 through 11, proto shield installed. 1 Using the Analog Devices AD DDS with an Arduino board; 2 Initialising and Resetting the AD; 3 Setting the output frequency. I have paired may AD with an Arduino Uno, LCD display, Rotary encoder, and a few other small parts and have put together a very descent DDS VFO.

Using digital pins 8 through 11, proto shield installed on the UNO.

Im upload the sketch to my arduino uno and success uploaded. Can someone try teaching me to solve the problem and where is the wrong in wiring arruino sketch? Im waiting your response.


AD + Arduino Uno (ProblemPlease Help)

Try I2C connection instead of parallel,. On the Arduino UNO the ‘double’ is the same as ‘float’ and only supports 6 or 7 significant digits. You are going to lose some of the digits when you multiply a long integer with 10 significant digits by a float.

Try printing out ‘freq’ after you have calculated it. If the answer is not then you are getting round-off errors.

I don’t know how far off the frequency might be. Send Bitcoin tips to: TomGeorge Design and Repair of industrial control systems.

Hi, Can you please post a copy of your circuit, in CAD or a picture zd9850 a hand drawn circuit in jpg, png? Everything runs on smoke, let the smoke out, it stops running Hi TomGeorge; Here the Schematic. Please help me to make correction whats wrong with my schematic of my sketch.

I want transmit in 7.
