Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[Bob Darby]

Rick,

It might be an adventure but ebay - doukstore  has a AD9959 Radio Frequency RF 
Signal Source Generator 4-Channel DDS Module DC5V for 50.99 and a DDS Module 
Driver Board LCD for AD9854 / AD9954 / AD9833 / AD9834 / AD9851 control board 
at 27.99 with push buttons and a LCD screen to set the outputs.  They also have 
a number of other DDS modules.

I have no idea what the quality is and I doubt there are English manuals or any 
schematics but for 78 bucks delivered it might suit.

Subject: [time-nuts] Simple open source microcontroller solution to tune DDS 
needed

I need a very simple controller to tune a DDS with up/down switches (imagine 
setting the time on a clock).  A DDS chip, such as an AD9836 would go on a PC 
board and a couple of pushbuttons would tell the controller to tune up or down.

Before reinventing this wheel, I thought I would see if anyone knows of a 
similar solution that can be leveraged.
What I would like is both hardware and software, where the software could be 
edited to accommodate the up/down buttons.  A last resort would be to write 
software from scratch.  My software skills are extremely limited.
Cutting and pasting code might work for me.

I need to be able to embed this onto an existing PC board.
I can't use a preexisting "daughter" card, other than to copy the design of the 
card.

Jim,

Forgot to add two things. There were two versions of the system - the rack 
mount had 6 slots and the portable had 5. And the rubidium oscillator is an 
Efratom FRK.

Re: [time-nuts] Argo AS-210 frame

[Steve - Home]

Jim,

I have an AS210 system that is on the “round tuit” list. It worked when I got 
it years ago but developed problems and had to be set aside. I have the -01A 
module controller, -02 freq comparator, -03 freq generator (500MHz), -04 
digital delay gen, and -20 clock module. I haven’t seen one with an 18GHz 
plug-in; that would be nice.

I have the manuals somewhere but it would take some archaeology to find them as 
I’m rearranging the lab.

One thing I remember is the modules will not work in a TM-series mainframe. 
Chances are good you would damage both the plug in and the mainframe. I don’t 
have a TM mainframe handy to see if the case parts might work. Mine was rack 
mounted and has very basic aluminum panels.

I’ve had all the modules except the controller out at one time or another. The 
controller looks to be a bear to remove and I believe that’s where the rubidium 
oscillator hides. It will be after the new year before I can have a look at 
mine but I’m happy to help if I can.

[time-nuts] European Electronics Systems Radio Clock Model 100

[GandalfG8--- via time-nuts]

Does anyone have a service manual or any information on the  
Europeanlectronics Systems (EES) Radio Clock Model 100.
The company was part of Siemens but closed down in 2005.
The Model 100 was supplied by Plessey Defence Systems to the UK  military.  
Some models could be GPS disciplined 
Any information would  be gratefully received for the Radio Communication 
Museum of Great  Britain.
(thanks to Robert with the hint about plain text !!)
Steve  Haseldine G8EBM
 
--
Now there's interesting!
 
With EES being quite a small outfit based in Maldon, Essex, or so I  
thought, I'm surprised to hear they were ever part of Siemens, are you  sure 
about 
that?
 
For some reason I thought they eventually became part of  Radiocode Clocks, 
although I could well be wrong on that  also, something not entirely 
unheard of :-), but do seem to recall  several mergers etc amongst the various 
UK 
off air standards  outfits.
 
I've got a few EES MSF and Droitwich clocks, including the earlier SFR060A  
and SFR200B, plus a 201 at the top of one of my racks in constant  use, but 
despite having some EES documentation I never did find much  on the model 
100.
 
With half a dozen or so of the GPS conditioned versions of the  model 100 
sitting in my garage I would also welcome some  documentation. My notes made 
several years ago seem to have disappeared but  I do remember being 
convinced that the GPS option was very much  an aftermarket afterthought, for 
that 
read bodge:-), based on a  retrofit Motorola Oncore if I remember correctly, 
and not really  something to get very excited about.
 
Regards, Nigel GM8PZR

[time-nuts] Argo AS-210 frame

[jim stephens]

Does anyone have a lead on the oscillator in this frame as far as repair 
/ replacement?


A friend has one with all the plugins, and one extra spot.  If I 
understand it, he also has an 18ghz plugin to fit that.


But currently the oscillator seems kaput.  He's checked all of the fuses 
he could get to according to the manual, and is looking for two others 
that currently alude him.


If anyone has had one apart and has some words on the process of working 
on them, he said he had a hell of a time disassembling things.  Also 
there are only shards of part of the case, and he seems to think the 
sizes of the panels are custom, and we can't rob from a donor TM-515.


Would appreciate anyone who has worked on one to let us know.

For quite some time (most of the last 10 years) Elektor magazine promoted 
BASCOM-AVR as an easy to use development language for the AVR micro. They have 
multiple books teaching BASCOM-AVR and a few hardware kits to go along. 
BASCOM-AVR is still available at

[time-nuts] Simple open source microcontroller solution to tune DDS needed

[Mark Sims]

The Arduino is basically just a processor chip on a breakout board that has 
some connectors, crystal, voltage regulator, USB interface.   The standard 
processor is an Atmel ATMEGA328.   The Arduino Nano is a shrunk down version 
that can be treated as a DIP packaged processor.  You can also buy bare 
ATMega328 chips with the Arduino bootloader pre-programmed.

ESP8266 is my favorite as of late. It comes in a "DIP Form Factor" and does
SPI and random DIO very nicely.

Even better, as to user interface, it has Wi-Fi and instead of physical
buttons, the UI can be as simple as buttons on a web page it serves up.

The digispark and digispark pro are also some nice <$15 development boards
that are USB programmable, use the Arduino IDE or AVR compiler, and have
just enough pins to be useful.

I agree - $20 for a Teensy, some jumper wires from solder holes on the 
Teensy to your breadboard, load up the Teensyduino libraries into the 
Arduino IDE and your SPI/I2C/serial interface is done.  I did this to 
write arduino code to drive a Silabs part.

yes to both.

There's also a fair amount of "non arduino" software that runs on the 
arduino hardware platform (whether ATMEGA or Freescale or some other ARM 
processor).


The pjrc.com teensy is available with pins sticking out, so you can 
mount it like a sort of thicker than normal wide DIP.


I've built standalone designs inheriting the processor schematic from 
the pjrc.com Teensy series (which use the Freescale parts which have a 
built in USB interface, useful for me).


If you're used to cross compilers using the usual GCC toolsets, and 
such, then you don't need the Arduino IDE environment (although it *is* 
easy, and gives you a nice prototyping platform).  You can program most 
of these chips using the JTAG interface, assuming you have a JTAG pod of 
some sort.  That gives you a single chip solution that still has a 
fairly clean development environment.

Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[paul swed]

Must have missed something here. Basic? Arduino uses C behaviors. God knows
everythings been written for it so maybe there is a basic language. That
said schematics are readily available and I believe its all open source.
Thats why its been so popular. Lots of nice simple tools for it also.

Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[Richard (Rick) Karlquist]

I should have said AD9832.  But that was just an example
that would work.  I may choose a different one for whatever
reason.

Regarding the Arduino board:  that is what I would call
a "daughter" board, which I can't have.  Is the Arduino
board open source, so that I can just copy the schematic
of it to my own board?  Is the Arduino software also
open source?

Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[paul swed]

bob
I also had trouble and assumed it was the AD9835.
That said I was curious. The DDS boards are always on ebay with mounted
chips and clock for $10.
Yes sir they are plenty to choose from still. I go along with Jerry's
comment on the arduino. Plent of code snips for control and DDS chips.
Additional note. The Arduino has SPi libraries and such to make 3 wire
control interfaces for numbers of things like the everset clock chip.
I have used these and I am by no means a great programmer.

Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[Bob kb8tq]

Hi

I’m having a little trouble spotting the 9836 in AD’s current lineup of DDS 
chips. The
stuff below is thus a bit generic. 

My guess is that you will have a hard time finding a canned solution. There are 
a
bunch of registers on your typical DDS part. The what to stuff where tends to 
be pretty
application specific (output frequency, clock frequency, amplitudes, modes ….). 
It’s not
rocket science, but it also will vary quite a bit from application to 
application. 

By far the most common “easy to use” programming environment is the Arduino. 
You 
still will be pretty deep into this and that to get anything done. A simple PIC 
done in
assembler would be the lowest parts count approach. That’s not exactly a simple 
thing
to learn just for a project like this.

Re: [time-nuts] Simple open source microcontroller solution to tune DDS needed

[Jerry Hancock]

I was using PIC chips to talk to AD9854 and 9851 and switched to the low cost 
Arduino boards as they are so much easier to program and have so much 
accessible I/O and adapter boards.  I know there is a lot of code out there for 
AD chips as it could be a little tricky to clock the bits out to the various 
registers.  The nice thing about the Arduino boards is that they have built in 
serial so whatever you write can be easily converted to USB control for both 
error logging and setting of parameters.  There are ethernet shields, wireless, 
etc.  There are a lot of AD9854 codes out there that can probably be used as a 
foundation for the AD9836.

[time-nuts] Simple open source microcontroller solution to tune DDS needed

[Richard (Rick) Karlquist]

I need a very simple controller to tune a DDS with up/down
switches (imagine setting the time on a clock).  A DDS
chip, such as an AD9836 would go on a PC board and a couple
of pushbuttons would tell the controller to tune up or
down.

Before reinventing this wheel, I thought I would see if
anyone knows of a similar solution that can be leveraged.
What I would like is both hardware and software, where
the software could be edited to accommodate the up/down
buttons.  A last resort would be to write software from
scratch.  My software skills are extremely limited.
Cutting and pasting code might work for me.

I need to be able to embed this onto an existing PC board.

Ed,
I am inclined to beleive you.
I have not found any RF-wiring into the "core".Only what seems to be heater 
flex cable.
A small part of the heater winding can bee seenin the gap where the flex cable 
is routed to theinnards.
The only way to learn the truth will be to unwindthe kapton tape and from there 
unscrew the lidand see if the oscillator really is inside.
Magnus got some pictures. He can upload themwhere he see fit.
