Re: PIC16f1938 and changing eeprom
I have tried with various approaches so far but none is working. I even installed VMware and valid windows XP os and still it did not work because of the USB interface.?
I surrendered and ordered a pickit 4. It's multiple times expensive than the target hardware.
Once I got it running (I hope it will) I will think about a possibility to change settings through knob sequence instead of the need for a programmer device. The current approach to change eeprom settings is not user friendly imho.?

Re: AT-100 build validation : L1 , L2 , L3
Thank you David and VA3RR for your comments.?
I found??to be quite helpful but it raises the question : When a schematic reads "4mm Air Core" does this mean 4mm from wire center to wire center ( taking into consideration the wire diameter as per the above calculator ) -or- the ID of the coil ( as in what drill size to use to wrap the coil around ) .? I suspect that VA3RR's comment that it does not matter much , but with a larger wire, large overall diameter and multi-turn , it might.
And here I am picking nits again.
Thanks to all.
Committing to solder.

Re: AT-100 build validation : L1 , L2 , L3
Hi. the best way - to follow recomendation you found on the original schematic.

Hi.
The tuning process will start automatically when large SWR is registered.
The most advantage of using External control connection to IC-705 - a tuning process will start automatically every time when you change a band with no requarement to touch PTT and choose eligible mode.

Hi David, Thanks for information¡
What do you get when connecting with a 3.5 mini jack cable? ?As you disconnected, the tuner continues to tune automatically when changing frequencies. ?I do not understand? Wys?ane z My?iPhone

No any special settings, exactly like AH-705

AT-100 build validation : L1 , L2 , L3
Good day all. After watching too many YT videos on the AT-100 , I admit I have one question remaining.?
My kits paperwork shows L1 as being a 3 turn on 4mm giving a 0.05uh value.
I have seen built kits on the videos that have a 3 turn L1 and? 4 turn L1.?
In one video , the builder shows the 'manual' and I can read that his paper reads a 4 turn L1.
My own feeble testing shows that the 3 turn is too low in value and the 4 turn is about right ( 0.023uh vs 0.049uh ).
Was there a board version change that prompted the 4 turn L1 ? ( e.g. a change in cap values requiring the change ) or is that an older version?
So.. should I proceed with the build per my instruction sheet , or build per value - testing each toroid before committing to solder?
Thanks - very much looking forward to the end product. Used to be that if a kit had toroids on it , I'd run as fast as I could away from it.
Now , I quite enjoy the fiddly little things.

Re: PIC16f1938 and changing eeprom
Hi, Onno
I think you can use a Windows emulator on your Linux machine and run PICkit 2 or 3 suite (not IDE)
To use pickit 2 you have to transfer a dll library from the version 3 you can find above. Version 2 nativelly does not support 1938 processor.

Hi Onno
Use MikroC for PIC , MikroE.

Re: ATU-100 firmware ver 3.2 has been updated
Hi,
Is there some documentation on how to compile the source code? Perhaps I can contribute too?

Hi, people.
I dont remember who exactly asked me about this problem, sorry.
Firmware 3.2 has been updated, display off timer issue resolved.
Ignore this update if you don't use a display off timer.
All the files and sources on Github as usual?

Re: PIC16f1938 and changing eeprom
I hope someone has experience updating the pic processor using command line instead of installing an ide to just push the bytes to the processor.?
I can access the pic processor, read the data and write data to the processor. It even works a little bit I expect I'm doing something wrong updating the eeprom. But I don't know what to look for or check.

Re: PIC16f1938 and changing eeprom
As far as I am aware, you need a PICKIT3 not the older 2 version

Hi,
Hope someone has experience with the following;
Ubuntu OS, pickit 2 and pk2cmd. That's the current environment I have available. I am able to program the PIC CPU but it seems I am doing something wrong with the upload of eeprom.?
I had a working (default) atu-1000. (Kw) but wanted to change some parameters as well upgrade the firmware. It was my understanding the hardware is wired the same as atu-100.?
How do you flash the eeprom to the pic normally and what settings are used???
Hope someone already figured out pk2cmd and changing settings for the atu-100.?
Unfortunately I lost the eeprom settings of the original flashed content. Perhaps someone in the group has as working hex file??
Thanks very much in advance!

Hello ,
Someone tested communication and automatic operation with the ic-705.
Do you have to set something up in icom?

Re: ATU-10 has been released
Thanks Glenn,? The overlay by value is how I found it,? R1 was the only resistor not populated so I went looking for it.? This sort of thing is to be expected in such a project, working it out is half the fun. Apart from that the build is going well, just the regulator?to fit on the underside.? The mosfets and relays are the hold-up on the top.? Time to order the toroids from GQRP club sales. 73

Good catch Ellis
Has been fixed on
The overlay by value section should be fine though.

Original ATU-10 board and Case available
Hello All,
About six months ago David sent an original board (cost recovery: ?board plus postage) to me. Thanks David. ?I then ordered the matching case from Alibaba (25x71x100 mm) to house the board.
The concept of gathering together all the hardware just to start the SMD process, let alone the actual process of soldering the SMD parts to that board are overwhelming for me¡ so, I am offering up these two - the case and unpopulated original board - for sale on a partial cost recovery basis. ?The overall cost to me (less postage) $12 CDN for the board + $10 CDN for the case.?
If anyone would like this pair (will not separate) - I will sell to a person on this group for $20 CDN plus postage costs to you.
Email me directly, off-group, if interested. ?
Thanks for your consideration.
Cheers and 73,
Dan. VE7CTN
