Workshop 3: Digital Input and Build a DDS
| Week 3 - Slides |
Sample working Arduino Sketches to build a DDS step-by step
These sketches require the following Libraries to work:
Encoder - from here
NewLiquidCrystal - from here
AD9850 - Would you believe it - a week after posting that library for the AD9850 has disappeared from the web - here is a direct download:

Note this DDS example uses a 16*2 character LCD with an I2C module attached. It would be straightforward to change this to a standard 16*2 character LCD display by changing just 2 lines - the include statement for the LiquidCrystal.h and the line that defines the LiquidCrystal display and it's pin mappings. Also note that there are several variants of I2D LCD adapters and you should identify your adapter and use the appropriate internal pin mappings as explained here.
