DDS VFO with AD9850 and PIC16C84
Here’s a wonderfully-simple project first done by Curtis Preuss, WB2V in the July ‘97 issue of QEX. The article was entitled “Building a Direct Digital Synthesis VFO” and was geared as a straightforward starting point for building and evaluating a DDS VFO based on the Analog Devices AD9850 chip.Curtis used the PIC1654 microcontroller but this project ported the PIC16C54 software to work on the PIC16C84 .
