10MHz DDS Sine/Square Function Generator based on the AD9835 using PIC16F628
An extremely simple and low cost Sine/Square wave generator based on the Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip. The frequency can be set for any frequency from 1Hz to 10MHz in 1Hz resolution steps! All this with three push buttons and a novel “sliding window” LED display. The controller chip is a Microchip PIC16F628. There is no wiring, and the PCB fits into a standard UB3 Jiffy Box.
