Uniden Remote Head Project

[eorange]

Do you have any interest in selling one or 2 of those adsb monitors that you've made? Or sending me the inform to attempt making them myself?

Thanks,
Robert

That was me who built the ads-b monitor. I am not interested in building and selling them (due to time and other commitments), but I'd consider sharing my instructions to make one. There are some prerequisites, i.e. a base level of knowledge that you really need to have:

- Know how to download the Raspberry Pi OS
- Know how to write the OS to a SD Card
- Know how to boot a rPi, login, and perform basic configuration with raspiConfig
- Know how to use SSH
- Be comfortable with the command line shell, and have the ability to troubleshoot if you type something in wrong.

If you can get that far...then you'll be able to load all the necessary software packages and install my software, which is freely available (under license) on github.

I don't mean to sound standoff-ish, but knowing the above will help you achieve success. I'd suggest starting out by purchasing a Raspberry Pi 3B or 3B+, and get it going with the full rPi OS with your HDMI monitor, keyboard, and mouse. If you can do that successfully, then you'll be in good shape.

Excellent, I have 3 Raspberry Pi's right now and just built the remote head that mancow designed and coded. As far as the other referenced knowledge goes, I'm confident with all of that. Can you share your github links?

Thanks,
Robert

That's good! You should have no problem. I need a few days to merge some code changes and move my instruction guide to the repo as a markdown file.

That looks right. The first in its own box should be 5v USB host/ client power then the two data and then two grounds. If you got the data+ - mixed up it won't damage anything. It just won't work. Just be sure to never allow 5v on any data lines as it's only 3.3v compliant.

OK, when all was done, I briefly saw the Uniden intro and got the serial port prompt but now I don't get the data, I only see the screen code that was programmed into the display. It seems like its not sensing the connection. rebooting ther scanner doesnt trigger the port prompt either and the Uniden monitor info on the screen hasnt been back through it all. Swapping the data lines doesnt have any effect. Reprogramming both the Teensi and the monitor were successful but there wasnt any change. Thoughts?

 

[mancow]

Thinking...

Not sure.

I'll try to get the new stuff posted today for you to try.

 

[eorange]

Do you have to put the scanner into a serial port mode?

 

[mancow]

The KDU initiates USB mode when plugged in. Once it sees the radio is up it sends the. NO button command to choose serial mode?

Short answer, no.

I just noticed the nextion monitor isn't the enhanced NX4827KO43_011 Nextion, I must have mistakenly ordered the basic NX4827TO43_011, I changed that during the Nextion programming as it propmpted be that the set model for the code was different. I ordered a new one but unfortuately it wont be here until Monday. Could that be causing the issue?

 

[mancow]

I'm surprised it even compiled but I just tried switching to that in the editor, recompiling and debugging and it worked. I was sure there would be a memory issue but it didn't complain. HMMM When I get time this evening I will fire it up in in the simulator with the basic selected and try running live against the Teensy and radio.

I'm trying to think of what could be different that would render it unable to communicate. If you go to their web page you can read the command protocol sheet. They have color legends by each command that tells what level of display the command will work with but if it were not supported by a basic it should have thrown an error when compiled.

 

[ra7850]

I'm surprised it even compiled. You have me wondering now if we could get by with a basic.

Hmmmm

OK, reprogrammed both the Nextion and the Teensie, still get the same results. Verified all connections per your diagram, changed usb cables to verify if that was not the issue and were back to right where we were. No prompt for the serial connection and it doesn't appear that the nextion display changes whatsoever, even after powering down and reconnecting the power. All of that and the Teensie still accepted so its a safe bet that its not dead. I even replaced the solder-less breadboard.

 

[mancow]

The Teensy, if connected and programmed correctly, should initiate the serial command and talk to the radio even without the Nextion connected.

Does the debug serial monitor display anything?

Tried reprogramming teh teensie, opend the serial monitor and got nothing there during programming, got the prompt to press the button on the teensie heard the windows driver unload then load.

 

[mancow]

You can't open it during programming as that's the same port it's using to load the firmware.

Disconnect it from the radio. Program it. Open the serial monitor. Plug it into the radio. Does it display any info?

Removed the usb cable from teensie to the SDS, using a different usb cable from the laptop to the SDS got the propmt for the serial port, restarted the scanner, plugged in the teensie board and nothing. It not sensing it being attached, however i'm able to reporgram it repeatedly, with success and without any compiling errors upon upload.

OK, Nope not 1 thing is displayed in the serial monitor

Im going to try another cable from the teensie to the SDS

Not sure if you saw my post from December, but I ordered a Nextion. I couldn't get the Tx/Rx to communicate with my Arduino, no way, no how. I am not a novice when it comes to serial ports and programming, but nothing I did made it work. The SD card upload was fine. I chalked it up to a bad serial port on the display and returned it, but never really got to the bottom of it.

Is there a reference do to upload the data to the sd card? Cable change didnt help

You can upload to the nextion via SD but not sure about the Teensy. I've never looked into that.

Have you tried swapping the USB lines again to be sure?
