Gentlemen:?
With the hardware all connected, I powered up the Arduino from my computers USB port, and the LED on both the Arduino?and DDS board lit up as well as the blank (16 square segments only) liquid crystal display.? I then uploaded the?"Blink" sketch, and the LED on the Arduino blinked away.? I then uploaded the Liquid Crystal?sketch with no change.? I then looked for the Rotary.zip file and I was not able to find that in my downloads, so I suspect, I have done something wrong in downloading both of these files.? I will have to confess; downloading software and getting it running is new to me!? The hardware part of this project, I feel that I have done pretty good at.? So gentlemen; what steps can I take to go on from here?? Thank you all in advance, de Karl, KO8S

First, make sure you have the latest version of the Forty-9er software from Farrukh's site:
?www.farrukhzia.com/k2zia?
Second, there are non-standard libraries that must be installed in the libraries subdirectory of where you installed the IDE. You can find any missing libraries by doing a search on the #include files:
#include ????????? // From Brian Low: https://github.com/brianlow/Rotary #include ? ?// Shipped with IDE #include ? ? ? ? ? ?// ? ? ? ? "
// Get the LCD I2C Library here: // https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads // Move all *_I2C files into a new folder named LiquidCrystal_I2C // in the Arduino library folder #include
Note that there are a bunch of libraries that use the same name, but are actually different. For example, the #include is NOT the same as #include ...case makes a difference! Put the correct libraries in the libraries subdirectory.
The fact that Blink works means you've installed the IDE software correctly. The fact that the rig doesn't work, unfortunately, could be hardware, software, or both. Just because the code compiles without error does NOT mean you're using the correct libraries. Check those first.?
If that doesn't work and you belong to a club, see if one of the members can help you track down the error.

Hi Karl The solution could be that you haven?t adjusted the display contrast! On the backside of the display, there is a small (blue?) potentiometer. You have to adjust this, when you see the 16 squares on the display. When you adjust the potmeter, the squares will disapper, but hopefully you will see charaters instead. Adjust for best readability, and forget all about it, hereafter.

Another thing to watch for is the?LCD I2C address "(0x27, 16, 2)"?in line 99, I have some that are 0x27 and others that are? 0xF3. I marked the address on the PCB on the ones I have.
LiquidCrystal_I2C lcd(0x27, 16, 2); ?// Create LCD object and set the LCD I2C address
The link below will help find the correct address.
| | | | // -------------------------------------- // i2c_scanner // // Version 1 // ? ?This program (or code that looks like it) // ? ?can be found in many places. // ? ?For example on the Arduino.cc forum. | | | | Preview by Yahoo | | | ?
|
Also, it is common for the constructor that creates the LCD object to be overloaded. For example, the code from our project uses:
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); ?// Create LCD object and set the LCD I2C address
which is different from many constructors. You may have to experiment a little before you find what matches the display you are using. As a rule, if I'm buying something new on the Internet, like a display, I always ask the vendor which library the device uses. If they can't answer that question, I look for another vendor.

Good advice!

Wow!? Thanks Jack, John and N0ngq for your responses to my (this) thread.? I can see now, that I am WAY over my head with this required, downloading of software.? For example, I tried to download the recommended sketch that would determine what liquid crystal display that I have.? I tried that, and in compiling that sketch, I got an error-stray # in program line 30, #include wire.h?
John advised that I increase the brightness of the display, and perhaps that would show characters; it got bright with adjustment, but no characters, only squares.? Also, I noticed that the back of the display board has a red LED lite when powered up.?
At this point, I will take Jack's advise and seek someone in the Detroit area (I do not belong to a radio club at this point of my life), or perhaps someone on a local repeater, that can help me with this software for this project.? Better yet, someone that?has completed this projected successfully.?
I feel quite confident, that my soldering and wiring is accurate, although, there is always a chance of error.? All components are mounted in my homemade case and I think that it looks very, very nice!? If I can find a way to attached a photo or two here of it, I will do that next.?
Regards, Karl, KO8S

Attached hereto, are?photos of my 49-er build and it is now ready for the software application.? The metal was taken from a old computer desktop power supply case.? I had to do some cutting and riveting to get it to the size I wanted and to eliminate some of the unnecessary cutouts.? The top and sides will be?clear plastic so all of the electronics can be seen and enjoyed!? 73, de Karl, KO8S

Good job on the case,. I'm impressed!!

This is the basic problem, I do not know enough about downloading, unzipping and installing the required software for this project.? If I did, I would have this project up and running, probably.? 73, Karl, KO8S

The attached Word DOC file contains suggestions for installing the IDE and downloading/installing libraries.

Jack;
I printed the DOC file above and tried to work through that today; no luck, because of my inexperience with computer downloads, files, and such things.? I was confused too, on installing the "non-standard libraries, that are found at the top of the AA source code file."
I was able to upload the "blink" sketch successfully though, but that is it.? After the blink sketch, I was looking for the rotary encoder sketch, to test that component, and I was not able to find it.??I?know that that I have a lot of required files missing.
With that being said, would it be possible for readers of this forum, that were successful on their build, to somehow supply me with the necessary software for this project, on a thumb drive or Arduino Nano, let's say; I can supply one or both of these items to the volunteer?? Otherwise, I am really going to be stuck.? With good working software, I'll then know for sure if I have any hardware/wiring issues in?my build.?
Thanking you all in advance, I am, Karl, KO8S

This is sent offline from the forum.?
Here's the offer. Send me an Arduino Nano. I'll send you one with the basic DDS VFO software installed. I'll check it with my VFO prior to shipment.?
It will be a few days before I can get back to the bench. Out of town for work. Can get it mailed out on Friday.?

Hank; your offer sounds great and I really appreciate it and your time in doing it!? Will?your Nano have all of the software on it for the display as well to make the radio fully functional?? I'll let you know when I get my Nano in the mail to you this week.? Thanks again, Karl, KO8S
