Sparkfun Minigen DDS AD9837 not working

Post by sruthisindu » Mon Oct 02, 2017 7:26 pm

Hi.
I had purchased a Sparkfun Minigen AD9837 signal generator in August 2017. Since then I have been trying to use through several methods. I used Arduino Uno for the SPI communication and used the libraries provided in the Sparkfun hook up guide.The only output I am getting on the DSO or CRO is the default sine wave of 120Hz and 1 Volt. I tried several modification in the code to obtain a sine wave of different frequency. But still the same default wave is coming. Is there any modification in the program and library for Arduino Uno as the library you have provided is for Arduino Pro.? Please help me with the solution as the component is very important for my project which has several blocks following your product.
