Function Generator


This project didn’t look complicated but it was. The MCU part is really simple: just some code for the Display, Keypad and DDS Communication.

A DDS is a chip that is driven by a hi-frequency oscillator. I used a 50 Mhz clock. Inside this IC there is a big divider that goes down to less than 1Hz. The resulting clock is passed to another counter which is connected to a Sine ROM table.  If you need a triangle wave, the counter is directly connected to the output.  For a square wave, the signal which drives the counter is redirected to the primary output.

Please note

All my source codes were taken from my personal projects.

Everything is for your information only. The C/C++ codes have been written
with ICCAVR. You can find the header and source CRT files by downloading their compiler.

All is for your information and everything is AS IS without any warranty of any kind. No other files are available and I don't make any modification for any body.
