Another DIY function generator using PIC16F628

An extremely simple and low-cost Sine/Square wave generator, known as the “Custom Function Generator,” is developed 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, a Microchip PIC16F628, is programmed to facilitate various functions seamlessly. There is no wiring required, and the PCB snugly fits into a standard UB3 Jiffy Box, making it an ideal solution for a Custom Function Generator.
