Re: ATU-10 3x more DC Current in SLEEP & OFF ?? #ATU-10

#1802

Hi Glenn.

I have already been studied the the schematic, but can't find any reason to this in the hardware, and any other software don't give any changes, bus it must be software related, to when it blanks the display, in standby or OFF mode.

It is by the way, the ATU-15 model, that looks like to be the ATU-10, but with the two LED's in the front.

i fixed it. It was in the programming
Thanks for the help

I can't help directly with the problem but a copy of the Schematic drawn by myself is available on David's Github page here...

It should be pretty close to your Chinese ebay purchase although Ref numbers will not be the same.

ok I have everything to program it, I did the QRP mod so I may have made a mistake.?
Thank you

Re: Inverted OLED display

#1798

Hi,
no need to flip the display physically…
there’s a parameter on the config for.
you need btw to program the pic, and need then a programmer (pickit2 or 3)
Look on the old group posts, there’s plenty of information for.

cheers

Inverted OLED display

Hello,
I bought a ATU-100 from ebay. It is one that operates off of internal batteries. It works pretty good and the only issue is that it has an inverted OLED display.

I took off the front panel hoping that I could just flip it and i looks more complicated than that

I contacted the seller and it appears like he is gone with the wind. As I said it works pretty good. Is it possible to flip the OLED? Also if it is possible would it be a complicated procedure??
Thank you

Impedance match range for ATU-100.

I am working on a story on how a AT-100 might be useful fora rig with a built in autotuner.

Now I? need info on the impedance range of the ATU-100.

Also if anyone has skewed the ATU-100 to very low impedance, like 4-5 ohms.? For very short antennas.? Think 80m on mobile whip.

Please include your callsign, to be included in author list

Cheers.

Hi Dave,

Have a look at the thread from a few days back called " [ATU100] Firmware version 1.6 for ATU-10 #file-notice" - there are details in there for modifying the parameters and resetting the checksum. The instructions are from David Fainitski in a message from the 13th November.

I haven't done it, but? the instructions look clear enough to me.

Best Rgds.,

OK, I read the GitHub file more closely and figured out the process to load the .hex file to the USB drive, so that worked and I'm ready to do some testing.

But what if I want to modify some of the firmware parameters from the default like "Time to Power off".

Thanks - Dave, N4ELM

OK, more reading and I think I have it sorted out.

I really like Notepad++.
I have used it at work for editing long command text strings.

ATU-10 How to upgrade firmware? #ATU-10

#1792

I have a couple of ATU-10s to upgrade from 1.4 to 1.6 firmware.
I bought these off Amazon and noticed the OLED display connections are soldered to the programming pins.
The example picture off the GitHub redme.md also shows the OLED soldered to the programming pins.

Do I need to unsolder the OLED pins to connect the programmer or can I leave them connected?
If I do have to unsolder the display pins can I replace the wire with a header and Dupont connectors?

Thanks - Dave, N4ELM

ATU-10 3x more DC Current in SLEEP & OFF ?? #ATU-10

#1790

Hi.

I have a new ATU-10 from ebay, that in SLEEP ( Display OFF ) and on OFF State, has a DC Current of 35 mA, but is OK, at only 12 mA, with display ON.

I can't at any diagrams see, what it can be, other that the PIC it self.
So do anyone have a clue on this problem ??

Re: Which Pickit for programming firmware

#1789

Hi, Bill

I would buy the most inexpensive Pick it 3 found on Ebay or AliExpress.
The programming soft you can find in the pinned message here .?

Re: Which Pickit for programming firmware

#1788

Hi Bill,

My ATU-100 has the PIC16F1938 chip which is supported by the PICkit 2
and 3 programmers (and presumably future versions). Same for the
PIC18F2520 which is also supported in the design for both the mini and
extended boards.

Like you I've been looking for a cost effective programmer and pretty much
settled on the PICkit 2 as the knock off ones are cheap and appear to be
well reviewed - although I haven't bought and tested one for myself.

Matt

Hi All -

I am interested in getting an ATU-100, and also would like to be able to update new firmware as it becomes available.

I see that you need a Pickit programmer.

Which version will work - there is a large difference in price between the different versions, and I am on a limited budget.

Thanks

Bill

Re: Which Pickit for programming firmware

I have a "Bolsen Tech" Pickit 3 and it works fine for programming the ATU-100.  I purchased it from Amazon, but I note the price has gone up at least by 50% since I purchased mine.

I am unsure what you mean by "After changing the values you will need to change also the last bite in each modified string - checksum". What exactly do I have to do?

Re: ATU-10: an alternative PCB layout?

#1784

Oh I hope the necessary firmware modification will be done soon, I built one board and wanted to give it as a Christmas present to a fellow ham :). Is there anything I can do to help speed up getting the firmware?
What is actually the problem with the current firmware? Is there any way to modify the board to work with the current firmware as a temporary solution?
(These are questions for Anton/ZAO rather than for Luca.)

Re: ATU-10: an alternative PCB layout?

Edited

The new firmware is not yet available unfortunately.
I am still waiting for it.
It is necessary to get in touch again with Paguo.
