In this series of videos I go though how to build a VFO based on the Arduino platform using the SI5351. The VFO includes IF offsets, frequency displays and a high speed rotary encoder. The VFO can be used for making home brew radio projects, tuning many types of radio equipment including SDR receivers. This VFO has good performance and is relatively cheap to build. No programming skills are required and I will supply the code for the project and go through how to configure and upload it. In the video I go through how the circuits work and cover troubleshooting to get the VFO working.
If you are experiencing any difficulties please drop me a line to m0xfx.channel@gmail.com
I am planning to make a Q and A video regarding this project.
Part 4
In this video we look at a new PCB for the project, take a look at future options including the ESP32-S3, TFT LCD colour display and look at mode sensing for LO frequency shifting and .

SPI TFT LCD Screen RGB Touch Display Module ILI9341
NOTE: The LCD driver IC used in this video is the ILI9341 320x240 pixel.
The code will only support this IC at this time.
2.2", 2.4", 2.8" or 3.2" sizes will work fine.
Also we are using a no touch display but a touch will work fine but
the VFO has no touch control functionality.

Many Thanks John for producing an excellent series of videos. My PC boards arrived yesterday and impressed with the quality of them. Just waiting now for the components to start the build. Its great that the code is available and makes this so flexible I can see its uses already in future projects

Great videos on the Si5351 build and code. I ordered and recieved my PCB's from John and they really are nice quality.

thak you i look forward to making this

@DuanesMind 4 месяца назад

Thanks for making the time to create these videos. I've been trying learn how the coding part works and how it fits with the hardware. These videos are an awesome learning tool!

Very good instructional series! Thank you

@paultomlinson528 5 месяцев назад

Absolutely brilliant, im so going to use this with my multi bitx project!

@stevelewis121 4 месяца назад

Hi John, awesome project! Is it possible to change the ILI9341 display pins in your sketch? I have a project with the TFT already connected to different pins and wanted to use this to try out your VFO.

Hi John, For your information, I have just tried compiling the code on my windows 11, machine using arduino ver 1.8.19 and I get the following errors: F:\Utils\m0xfx\SI5351_VFO_001\SI5351_VFO_001.ino:57:24: warning: overflow in implicit constant conversion [-Woverflow] int Cal_si5351 =(122360);// need to go through calibration routine to get this figure ^ F:\Utils\m0xfx\SI5351_VFO_001\SI5351_VFO_001.ino:78:36: warning: narrowing conversion of '1.0e+6' from 'double' to 'long int' inside { } [-Wnarrowing] long freq_rangeHz[3]{1e6,10e6,100e6}; ^ F:\Utils\m0xfx\SI5351_VFO_001\SI5351_VFO_001.ino:78:36: warning: narrowing conversion of '1.0e+7' from 'double' to 'long int' inside { } [-Wnarrowing] F:\Utils\m0xfx\SI5351_VFO_001\SI5351_VFO_001.ino:78:36: warning: narrowing conversion of '1.0e+8' from 'double' to 'long int' inside { } [-Wnarrowing] Best regards...........Peter

Hi Peter Thank you for the detailed feedback, I will look into this. Quick question: what micro controller is the IDE set to when you try to compile? Also under Tool/Boards Manager search for "Arduino AVR Boards" I have version 1.8.6 installed and it's compiling.

@M0XFXUK 5 месяцев назад

Hi Peter, I think that I have figured out the issue. Apologies it was an oversight on my part. I will update the code and links. Here's a quick fix. Note: This is for sketch "SI5351_VFO_001" only! On line 57: the integer type is defined wrongly. Replace the "int" with a "long" type variable, it should read long Cal_si5351 =(122360); . Also on line 78: comment out this array as it for the seven seg display and is not being used in this sketch. So it looks like this //long freq_rangeHz[3]{1e6,10e6,100e6}; The compiler seems to overlook the integer type issue on the later revs of the IDE and I'm not sure why, it could be that I have been using 32bit micro controllers with the IDE. Please let me know how you get on and thank you for bringing this to my attention Peter. Best Regards John

@@M0XFXUK Hi John, Just tried your fix and it compiles ok, Thankyou. I know that with the Arduino that different versions of the libraries can give various compile issues, so it's nice to know what versions are being used in the code. Anyway excellent work . Best regards............Peter
