Summary of Another DIY function generator using PIC16F628
This low-cost Custom Function Generator uses the AD9835 DDS chip to produce sine and square waves from 1Hz to 10MHz with 1Hz resolution. Controlled by a PIC16F628 microcontroller, it features three push buttons and a sliding window LED display. The design requires no wiring and fits neatly into a standard UB3 Jiffy Box.Parts used in the Custom Function Generator:
- Analog Devices AD9835 Direct Digital Synthesis (DDS) Generator chip
- Microchip PIC16F628 controller chip
- Three push buttons
- Sliding window LED display
- Standard UB3 Jiffy Box
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.
