Ver3 to CEC

 

Hi Evan,

Changed baud rate, could read the Nano.
Loaded the display files through the XLoader.
Loaded the CEC software ver 1.20. Compiled and uploaded. Again read it in the manager with the baud rate suggested. Read successfully.

Then tried to connect it in the box. Switched on and no display.

What could be the?problem?

The stock raduino which I have does not et read by manager 1.11 and 0.97. Is there any version which can read ver3 software. Tried all the baud rates.
 

Rajesh, did youbuse nextion or 16*2 lcd ?

?Eitherway you have to configure it in ubitx.h file before really uplading. I assume you might have done it.? However try to check . All the best.?

Rajesh,

First, verify that all of the boards are plugged into the correct pins in the connectors.??
NOTE: If you replaced the Nano, then did you get one without the headers soldered onto the Nano, and then soldered the headers such that the reset button is between the Nano and the Raduino boards when the Nano is inserted into the Raduino.? The Nano used in the Raduion must have the header pins on the "wrong" side of the Nano when compared to a Nano that is supplied with the headers already solder to the Nano board.

Next, let's eliminate the hardware as an issue.?
- Remove the Nano from the Raduino board.?
- Plug the Raduino board back into the mainboard (if you took it out to pull the Nano)
- Then power on the rig.?

The stock display should light up with grey boxes across the top row.? If the display lights, you may deed to adjust P2 to get the boxes displayed.? If the display does not light, then check the 5 volts on the output of the regulator on the Raduino board.? It should read 5volts.? If not, then try to isolate where the 5volts is shorted, or if the regulator has failed.

On my v4 board, the Display connector reads 5 volts on pin 2, .85 volts on pin 3 and 5 volts on pin 15 without the Nano.

You can also test the stock display by supplying +5volts to pins 2, 3, and 15 of the display connector.? Pin 1 and 16 are ground or negative. You should see the backlight LED light up, and have grey boxes across the display.

Once that testing has been done, and assuming that there were no problems, or you found and correct the problem, now plug the Nano back into the Raduino board.? This time we will test the Raduion unplugged from the mainboard.? This can be done with a 5volt USB supply, or when connected to the USB port of your computer.? The onboard regulators of the Nano are enough to power the Raduino and display.

I would highly recommend that you use Xloader and the "UBITX_CEC_V1.200_16P.hex" file to load into the Nano.? That way we would know that there is not a configuration issue with the compiled program.? Here is the Xloader download page:


Above are my suggestions.? Please do the research and verify it for yourself.? All of the schematics are on the HFSignals.com pages:

Hello Rajesh....

If you have taken the raduino out and replaced it various times, I'd double check to make sure one of the connecting pins has not missed it's target hole and is folded back where it escapes being seen. And double check the board's supply voltages to the raduino.

Sorry, this is the limit of my technical guess-work.

Hi

Thanks for the revert. I use the standard lcd display which comes with the box.

Have uploadrd the corresponding hex files as well.

But still the display does not light up.

Since I have ver3 running currently, ehich is the manager for it. Ver .97 and 1.11 dont seem to be able to read the stock raduino.

Rajesh,
First off, did you follow the suggestions in this message?
/g/BITX20/message/80271

NOTE: Please ignore the typo Arduion, it should have been Arduino.

There is only one file that needs to be loaded into the v3 uBITX Nano with the stock display using the Xloader.? For your situation that would be:
UBITX_CEC_V1.200_16P.hex

The tft files are used by the Nextion display, that you do not have.? They are not loaded with Xloader, rather they are transferred to the Nextion through a microSD card.??

From what I can understand from your messages, you are not seeing the backlight turn on in the stock display.? That is a hardware issue and has nothing to do with software.? If your setup is working EXCEPT for the backlight, you should be able to read text on the display if you shine a light on it at an angle.? You can adjust the contrast with the P2 control on the Arduino.

I believe that you are at the point that the best option would be to find a local club or ham that can help.? I am running out of suggestions for you to be described over the messages board.

Good luck

Shall keep?you posted when that?happens.
