Si5351 VFO/ Sig Gen - Arduino Nano- Homebrew

A homebrew VFO/ Signal Generator using Si5351 clock chip. I used a 1.3 inch I2C OLED and
I will share with you the changes made to the sketch (orig by Julio Cesar) to make it work.

Without module connected everything works smoothly no hang no freezing display

[@mm0umz426]

Then check the code for the si5351 or the pin connection

[@TheNixJohn]

As i connect si5351 module after feq switches clicks whole system freezes.whats the issue?

[@mm0umz426]

Hi,it seems like the encoder switch is not being read at all. Check the code, make sure you have the sketch for the encoder. If it freezes, it has to be a code issue. Hope this helps.

Hello would this replace the raduino on the ubitx kit 🎉 thanks ✅

[@mm0umz426]

@@echo-_-radio hi,it will work but some changes would be made in the sketch to adjust the frequency offset to match that of the units,honestly I haven't done it but there's a possibility, 73

@@mm0umz426 Thankyou that’s great 73 👍

[@andreabaldini7073]

hello I would like to ask one thing, how do you keep the last used frequency before turning it off ? every time it is turned off or restarted the frequency returns to the start

[@mm0umz426]

That's the way the code is written my friend. When it's turned off then on,it always starts at the first line of the code.

[@atul_sane]

Why dont you share your sketch from google drive, that will help viewers

[@mm0umz426]

@@atul_sane sorry my friend as I can't publish the sketch for copyright reasons. I only modified it for my application. Search Google for"cesarsound"

How do you use this to received signals/Audio ?

[@mm0umz426]

Hi Alnoor,this can be part of a receiver. It's a signal generator for Rf frequency.

[@mm0umz426]

This is only a generator of signals,which can be used as part of a receiver, a direct conversion one or a superhet type.

[@x-hacker-2648]

Can you send the file

[@mm0umz426]

It's available online @arduino projects, I only made mods to suit my own kit,73s

Hello! I made this project Julia. However, I miss the output of the second CLK1 generator so that it would give my IF. Do you know how to modify this sketch. For CLK1?

The original code and Schematics is by Julio Ceasar.See Arduino Project Hub @internet. You will see the mods I made in the code in my vlog. Hope this helps.

Code and Schematics in arduino Project hub. It is not my design,only made modifications in the code. Credits to Julio Cesar.
