Raduino not working 0 Volts on Pin 6 (red wire) #ubitx-help #ubitx

 

Hi,
I am strugling with a uBitx. The Raduino isn't responging to any input.

There is 0 volt on pin 6 (red wire for the funktion button) to ground on the yellow wire (pin 4) or common ground on the chassis.

I guess that without power we can't switch anyting. I tested with and without the encoder connected etc etc.

Do I have a faulty arduino board or can this be fixed with software?

Looking forward to your replies.

If you have zero volts on pin 6 then either your software is not
working correctly or the nano is not working correctly.

Tests to-date seem to indicate that the Raduino board and its Arduino NANO
are working fine.? It gets all the way through boot up and displays the first data
screen.? What is not happening is front-panel controls do not seem able to
control it.? This would probably not be a Raduino or NANO problem, and not
a problem with the uBITX main board.? At this point it still looks like a wiring
problem of some sort.?

uBITX and Raduino boards are factory tested before being shipped out to
buyers.? Of course this is done with a set of test harnesses and not with the
wires that you have to put together for your uBITX build.? Connecting up a
simple wiring harness seems like an easy task, but it is surprising how many
have trouble with that.? I want to go back over the wiring instructions to see
if there might be some way to make the process easier and more clear.

We may eventually want to take this troubleshooting process off-group to
avoid using excessive bandwidth, and then come back to the group later
with a documented solution.

Will get back to you sometime tomorrow.? I'm busy today with other tasks.

Rogier,
Don't know what of the flavors of software you are using.? That pin is used as a digital port and the internal pull-up enabled in the 'factory' software posted on github.
One of the ways to trouble shoot the Radunio, is to remove it completely from the uBitx and power-up via the USB cable.? If all is OK, you should have ~4.5-5V on pin 6.

Is your display working?? ?I should be doing a "uBITX v0.20" splash when powered-on.

You said you tested without the encoder connected, I assume you also disconnected the F_BTN? (as part of the encoder assembly) too.?
Checked that the F_BTN is NOT always stuck in the closed position.? Rather state the obvious, then have that missed.

Regards,
Gary

Don't know if this will help but when I assembled my unit I accidently staggered the display pins. I only found this out when I assembled a case for it and my mounting holes were off. Another area is the pins on the board. They can be staggered accidently. Have you tried connecting the USB port to ur computer and see if it will fire up?


Hope this helps

Rogier has a few threads open on his problems.? Casually, hard to keep up with where he is at the moment.
He has shared more information than is contained in this thread.
I usually _try_ to look a threads I've responded to, to see if progress is made or if additional inputs? / coaching might be helpful.
I can see how using non threaded email, one might not understand this perspective.
So, please if you have an issue where others are trying help. Please stay on the same thread e.g. subject line.? Easier for others taking their time to try an help.
 

Yup, this one has been hard to follow.
Let's keep this thread going, seems a fine title for it.

Doing a search for "Rogier", I find these:
/g/BITX20/message/47715
/g/BITX20/message/49091
/g/BITX20/message/49445
/g/BITX20/message/49496
/g/BITX20/message/49518

I'm assuming all his posts have been signed "Rogier".
It seems he still has the original firmware installed, the Raduino worked at first,?
but now it powers up with a display of "LSB A : 7150.000" and fails to respond
to the function button or the encoder or the PTT switch.

He also reports that? ? "There is 0 volt on pin 6 (red wire for the funktion button)
to ground on the yellow wire (pin 4) or common ground on the chassis."

His iMac does not see the Raduino when hooked up with a USB cable, but then?
that's not unusual.? Many possible reasons for this.
?

###########################
I've got my uBitx Raduino totally unhooked from the wiring harness and the uBitx board,
laying flat on my desk.? Have a USB cable to a laptop to power up the Raduino.
Using a corner mounting hole of the Raduino for ground, I see 4.6 volts on the
first four pins in from the right on the top connector (ENCA, ENCB, FUNCTION, PTT).
The 5'th is ground, so I see 0 volts there.
The 6'th is 5 volts, and I see 4.7 or so because of a diode drop in the Nano.
The 7'th and 8'th are analog pins without pullups, so are pretty much undefined.

Be very careful when probing the 6'th pin that it does not get shorted to adjacent pins
by the probe, but if you see around 4.7 volts there that will verify that the meter is set up correctly.

If the Function button pin is low and the others high, could be there is something like a piece of wire
or a glob of solder on the Raduino that is shorting it to ground.? With power off, how many ohms
from the Function button pin to ground?? I see several mega-ohms.
A shorted function button will put it into calibration mode, and it may be waiting for the function
button to be released before updating the display.

If all four of those pins on the right side are low, that suggests more serious trouble.
Perhaps the flash program in the Nano got corrupted?? (I doubt it!)
Perhaps the IO cells into the Nano got blown? (Not all four!)
I'm betting the other three pins are high, and the Function button pin
is getting shorted low somehow, and thus hanging up the processor.

I am (unfortunately) counting in from the right, so my pin numbering?
is reversed from that shown at? ?

These might not apply to Rogier's issue, but since I have already typed this up, it may be still helpful to him or someone else.

I had 2 issues when trying to connect to the supplied Nano on the Raduino board to my Windows 10 machine.
1. USB connection.? ?I started with a cheap working cable (that I use with Segger J-link debugger boards all the time) and did not get a power connection.
? ? Fiddled around on a Friday evening, I am aware that the USB connector on the Nano clone board may be an issue. (socket + connector tolerance)
? ? With the right pressure from the thumb, I could get intermittent connection.? OK, making progress.
? ? Went through the stash box and found a 'better' (well at least more expensive) USB cable with ferrite chokes on either end, that made solid connection.
2. Driver. (nothing found on PC comport)? Well there had been some discussion of issues with Macs (that wasn't forefront in my mind at this time)?
? ?With hesitation, I downloaded a CH341 driver for Windows.?? ?(installation complained about not being successful, but the driver was working)

Now I was up and running. Time for an adult? refreshment, sofa and bed.
Project gets side tracked for other things.? When I get back to playing with the Nano clone,? What do I do?? Use my everyday cable.
It doesn't work. Momentary lapse of sanity.? Get the 'better' cable and all is O.K.

This was the first time I played with a Nano clone.? My only experience with Arduino is the Uno R3.? I use them often for adding quick instrumentation, remote pin control of hardware under test, etc.
Clones are cheaper and make sense to use in various projects, like this one.??
However, If your budget allows, I'm an advocate of having at least 1 of the mainstream top tier manufactured products when you are self teaching.
Having additional obstacles to overcome when your intent is to 'learn Arduino' can be frustrating.??

Gary
 

This might help :-)
 

Hi Gary,

Thanks for sharig yoru experience.

I was able connect to the Raduino and load software. But it still did not fix the problem I even ended up resolding the board thinking that there might be a cold weld causing the missing voltage.

This morning I received a and was able to load the software. I noticed a mayor differece in the fact that the led's on the Arduino are acrive whil on the failed Raduino there is only one sad led.


Meantime I ordered a new Raduino board from Farhan. Meantimme I am going to try to recplace the current one with this generic one, wish me luck...!
Mike aka KC2WVB
 

Sweet, thanks.

Rogier,
Thanks for sharing your progress.? Best of luck on the swap out.?
Have a fun weekend.

It as a dearing undetaking but with some patience a hot soldering iron and solder sucker I was able to pull the Raduino from the board and solder the Generic Arduino Nano.

Before installing the new Nano I was able to compile the software but after I installed it its failing.
I tripple checked for shorts between the solder points but could not detect any. It was a good excersize in soldering but I am not going to waiste more time on this becuase by now I am sure the error is in the board that carries the Raduino. There is one on its way from India untill then the project is shelved...
 

Did you check for a short from that function button wire to ground?

Excellent job at removing the Nano. I too will probably be ordering the Raduino board from India because I am beginning to believe my issue is your issue.?

I did put together the BitX40 this evening. Right now its on a bare bones chassis and it has been functioning without a glitch for an hour or so. If it is still stable tomorrow I'll go online and find a nice enclosure for the radio.

I had been thinking that my UBitX's problem was restricted to the encoder because, supposedly, the boards are tested prior to being shipped. I am beginning to believe the testing in India may be restricted to the main board and not the Raduino.?

Any how, good luck with the replacement board and if I run into difficulty finding how to order one for my rig I will drop you a note asking for the specifics.?

I have yet to perform the voltage test on the Nano. I ran out of steam after the 40 meter rig was completed but I will make the test tomorrow. Incidentally, should the reading across the two pins be spot on 5 volts or is there some leeway?

Thanks again and best wishes,

Mike

Probably more like 4.5v if taking power from the USB host, no other connections to the Raduino Nano+display assembly.
All four pins on the right side of that connector (for ENCA, ENCB, FCTN and PTT) should be at 4.5v to ground.
If any of them are not up around 4.5v, power down and measure ohms from that pin to ground, I am very curious.

It is only with a Nano that has been programmed with stock firmware (as they arrive from hfsignals)
that will have around 4 or 5v on those four pins.? A raw unprogrammed Nano will have those pins floating,
and they could measure anything between 0 and 5v.

Yes and it isn't even connected to the board.
 

Yep on the board with the replaced Arduino Nano it has all the 4.5V you asked for :-)

Perhaps its "just" a programming issue.
Strangely enough if I recall correctly I was able the upload the software without error message from the Arduino application on my Mac witch.
After I mounted it on the board it did give me the error message.
I read somewhere that the issue might be the fact that my iMac has USB 3.0 ports. So I installed the software on my old MB Pro, loaded the driver. But now the second I connect the USB cable the MB Pro instantely crashes hard.

Will try later with an old PC running Umbuntu Linux....
