Wave Generator with U1
A signal generator project using the InvIoT U1 board and a module with the IC AD9833 DDS.
The module can generate from 0 to 12.5 MHZ square, triangle and sine wave.
There are many boards with the AD9833 chip. I use the one that has an onboard applifier.
Step 1: Set up
1. connect the AD9833 module with the U1.
VCC - 5V
GND - GR
FSY - D10
CLK - D13
DAT - D11
2. Upload the sketch that is found in the library of the InvIoT. Open your arduino IDE, file/examples/InvIoT_U1/applications/signalGenerator 3. press upload
