Hi again,

First of all a data point: The cracked display meant that the touch screen did not work causing what seemed to be a lockup.
Therefore I purchased a replacement display it is identical in every way to the original one apart from one thing. It only displays a white screen, no graphics.
On the basis that it could be the initialisation bug discussed in the forums, I compiled and uploaded the firmware with the fix to the Raduino (successfully).
I still get the white screen. With the new display I turned the volume to maximum and heard birdies and whistles so lots seem to be working - this did not happen with the original display. I also have an 1.8" display with the same controller (used on a Raspberry Pi) - and the same pin out; plugging that in displays something. I think I got a duff replacement display so will order another one. Looking around I get the impression that the IL19341 controller operates on 3.3v but I noticed that the Raduino uses 5v. I can't track down a data sheet so I was just checking that 5v is OK.

Dan,

Thanks for the info.? To this point, I have only used .hex files in the Raduino.? I need to successfully compile and build a version, and will definitely include your code.? When I do, I'll see if I can figure anything out about it not displaying for CW.

I'm still experiencing infrequent times where the S-meter is frozen mid-scale.? Have you run into that?

Regards,

Mike

Hi Andy,

I'm glad to hear it fixed your white screen problem. I've made some changes to the code since then, and can get you an updated binary if you can't compile yourself, though I don't know that it will solve any of your specific issues.

1) the stock code changed the LO in steps of 875Hz, which is ~1ppm, since the PLL target is 875MHz. I know that my setup is also slightly off of zerobeat, but I figured "close enough" and left the step size as is. I could make the step smaller, but then you'd have to do a lot more turning. I'm hoping to get a "momentum" thing built in to the encoder, so if I get that in place, I can drop all the step sizes without sacrificing speed of tuning.

2) This is quite likely due to the step size of the cal

3) A couple other threads have mentioned issues with keying, so you're not alone. I haven't looked into improving those functions at all, so I can't comment as to how easy or hard a fix might be.

4) I haven't experienced much, if any, lag on my touch inputs recently, but I know that if it's not well calibrated, it will drop inputs because it will think you're pressing where no buttons are. If you haven't already, remove the protective film that shipped covering the screen. Try recalibrating the touch screen using the stylus, even if you plan on operating using your fingers, and see if that helps.

hello given there are a few different sets of software for the ubitx v5 whatare the latest that are available and from who? many thanks?? dave c gw0nvf

Hi Reed,

I finally managed to get your arduino hex file uploaded into the nano and the display back to what appears to be normally visible. The 17M selection is working properly, albeit sluggishly,? with this version also.

I managed to get the test menu to work also somewhat sluggishly.

1. I am unable to set the ref FREQ to 10 000 ; the closest is 10500

2. The zero beat adjustment adjusts above and below but does not produce a zero beat state. The receiver works and I am able to hear WWV on? 2.5 MHz and CHU Canada on 3.330 MHz The zero beat adjustment allows me to hear the signals and voice components/announcements but continuously has approx a 500 Hz tone superimposed on the time signals which appears as though it might be due to the freq setting from step 1. not working as text instructions state it to be set.

3. I am able to select Hand Key setting and in CW mode it outputs the full 10 Watts on 80 M band on key down; however if I key a test transmission at about 10-12 wpm with the hand key the lag between key down and RF output is serious problem (no setting of key delay helps improve). It is so bad I would not be able to use it for CW operation. I plug the hand key into the Mic jack and have the key control the PTT; in CW mode it generates CW sidetone signal but hand key does not work when plugged into the J4 Morse Jack at all.

4. Changing modes using the color display buttons and a stylus works but it also exhibits serious delays and even sometimes requires selecting the new band a second or third time to finally get it to change. It is almost as if the morse code hand keying and TFT screen servicing routines get hung up in an idle code loop delay of some sort that makes the overall operation seem sluggish or seriously lagged or unresponsive/insensitive.

But on the plus side The BRICKED white screen appears to have been cleared up; The only other possibility is that the TFT/nano daughterboard pair has a problem that is creating the sluggish performance; and HFSignals promised replacement has not been sent to me and thus I am unable to compare it with a supposed new one. They promised on two separate emails to send me a replacement however have not so far lived up to that promise.

Any suggestions now Reed?

Thanks for the hex file download

Andy

Thanks Reed!? Found it, used it, and now I have a voltage display on my screen.? It would have been slightly easier if they hadn't cut the wires flush with the connector but I got it done ...

Andy,
I have a little Beofeng radio and mic and the mic’s are known for their week mic signal so back in August I bought “10x5 mm 30-40 dB electret condenser microphone high sensitivity pickup” 5 pieces for $3.95 including shipping. This item is still available from eBay.
1 I replaced?the small pick up with the 10 mm one. (I had to cut away the plastic ring around the small pickup)
2 I drilled a couple more small holes in the microphone face above where the new pick up sits

PS: I am using CEC firmware version 1.20.

Hi Mike,?
I took some time this weekend to look into the code. Indeed, the analog pin A7 is read only during RX, in a process called idle_process() .With a very simple code change I was able to read the analog pin during TX. but only for PTT and TX from CAT. It does not work when keying down (I don't know why, I wasn't able to figure it out).
So now I am using A7 for both S-Meter (during receive) and for FWD/REF during TX.?
The code change as follows:
ubitx_20.ino, line 1515, insert the following lines between ?" } //end of check TX Status" and ? "//we check CAT after the encoder as it might put the radio into TX"

On uBitx v6, A7 is definitely available. It's only connected to the CONTROLS1 port pin8, and that wire isn't connected to anything on the corresponding wiring harness in the kit. It can only be used as an analog input (can't output at all, but you can threshold it to make it pseudo-digital). In the stock software, you'll see it listed as a define called "ANALOG_SPARE", but I'd recommend renaming it to whatever purpose you use it for, if you do use it for something.


Reed

Are there any analog pins available on the Nano of the V6?? From looking at the documentation it looks like A7?might be available.? Anybody know for sure?

Awesome!
Thank you all very much

weight is 2 lbs 4.3 oz.

Enhanced has more memory. Surprised that it didn’t compile for basic, as I had no problems compiling it for basic 5”. I seem to remember that someone else had a compile problem for a basic. But don’t recall the fix.?

when I am in front of my system late next week I will try it. I know that I ran this close to the maximum on the 5” basic. ?One of the spectrum displays takes a lot of memory. Had to reduce it size to compile on the 5”basic.?

What did you do to upgrade the mic Mick?

Hi all,
I have been looking around but cannot find the dimensions and weight of an assembled 'full kit' uBITX v6
Does anyone know what those dimensions and weight are?
Thanks

Another clue, when unit is powered successfully the 5 volt regulator on the raduino gets quite warm. You can affirm its action by checking to see that there is 5 volts on the board.

With my v4 it is visually easy to plug the raduino into the board and be off by one pin.

If a tiny piece of wire is shorting something, a good power supply may stop outputting voltage then.

The need to debug is part of the journey. My v4 is on the bench because one of my mods isn't properly installed, even though it is working nicely on transmit. Debug time, I will find it.
