Hello,

This post announces and provides the Freeware Propalyzer Distribution.

This is not nag-ware, etc.... Bug fixes may come if issues are deemed significant by the author.
The release is for Windows PC users with .net 2.0+ pre-installed. Linux mono .net is not supported.
This program does not compete with "sponsored" applications; the features available are different.

Please see Propalyzer.txt in the .zip for user details.

Propalyzer Purpose:

To provide a serial interface logic analyzer GUI for a Propeller running capture code.
Propalyzer is designed with HP analyzers in mind. It is not an oscilloscope application.

Specifically, the timing diagram is displayed in the main window. Users
have control over triggers with a bit mask and an arm state. Users can
define groups for making data more meaningful.

Features:

- Serial communications with Propeller
- Compile and Download Propeller with Propellent program
- Flexible serial port settings
- Propeller Clock period to 2 second sample period (2Hz to 80MHz or more)
- Easy to use Mask, Arm, Trigger, Display settings
- Two waveform display color variants
- A state list window
- Pin Group definitions
- Display context controls
- Key stroke display controls

Propalyzer is a Logic Analyzer; it does not collect and show data in real time like
an Oscilloscope. If you want an Oscope use a program that advertises such a feature.

Please use this thread for Q&A, application feedback, or to point out errors or situations where
Propalyzer does not work as expected. At some point the application may be posted in the obex.

Version 1.0.1.4a:

Allows user to specify the Clock Frequency used for sample periods.
Enables Window edge resizing. Gives Propalyzer an icon for Windows.

Fixes State List window restart problem.
Fixes a Comm Port Options problem.
Fixes an issue where traces added to a group are not correctly dislpayed.

See Bug/Feature record in Propalyzer.txt for update history.

Version 1.0.1.4 had an initial setting problem that 1.0.1.4a fixes.

Propalyzer.exe will not start any install; it will just work if you have .net 2.0+ in your PC.
Please make sure your com port speed is set to 115200. Read Propalyzer.txt for usage.
It is recommended that the PiggyBack Propeller have it's own crystal for use with Propalyzer.

Thanks Steve, great work, and thanks for sharing.

and my apologies for not testing yet.

Hi jazzed

After launching Propalyzer: I only get

Sapieha,
Sorry for the trouble. Please find corrected version Propalyzer_1011.zip attached in the top post.
It is simply amazing that the program ever worked for anyone except me.

Hi jazzed

Next problem.

Look at Pictures.

First look on My setings. My ComPort is "Com15" but On butons marked in picture On Butons it stil wil have "Com1"
Next If I drag Setings window it hides below Propalyzer

Ps. After restart av Propalyzer it function corect !

Sapieha.

Wow! You have many COM ports! Thanks for your efforts and not giving up. I was able to reproduce the problem.
For the time-being, I hope restarting the program is an ok workaround. I will update the application with a fix later.

Another day another update. The program should not change for a while after this.
Enjoy :)

@Jazzed (or anybody else)

You should offer a "Propalyzer PCB board" (populated or unpopulated, SMD or through hole). Something that has two propeller chips with the proper electrical connections, and possibly a USB to Serial chip too. It should be made to just plug into a standard socket, and would be left there during development. Once done, just pop it out and replace it with a regular propeller chip. I'd try and use your program, but I don't want to have to solder chips together or bend pins and all that. If you do it with SMD then it could occupy the same area as a regular DIP prop.

@SLRM,

Yes, I've tried. The QFN is just beyond my abilities though. Maybe a QFP with SMT connectors. We'll see.

Jazzed,

I have the same problem, regardless fo the advice that it is "easy" to go SMT. But the PropII will only be offered in SMT, as far as I can tell, so a permanent solution has to be found. Perhaps Parallax will offer a breakout board with xtal, regulator and and other naughty bits.

@James,

At least you can see the pins on the QFP parts :)

Was thinking about making a QFP into a "J lead" and using that instead of a QFN.
If the Parallax store is open for sales this weekend, I'll try that.

Jazzed:

Did you use level shifting with this circuit ? I was wondering how fast the series MOSFET circuit can switch. Have you any idea ?. Something like the 2N7002.

I mean something like this circuit:

Excuse my ignorance as I am new to the Propeller world, but I am working on a project that I could use a logic analyzer. As I understand, I can take a spare propeller demo board, load the spin code in the propeller, install the software on my PC, grab some alligator clips and have a logic analyzer?
WOW!
Does this require the Propalyzer or Propalyzer2 board?

Thanks

No this does not require special boards. It is a great tool. It is a pity there aren't cheap probes to be found.

Can I get by with some micro alligator clips from Radio Shack if I am looking at timing signals @ about 500Khz?
What type of probes are typically used?

Thanks

These are great:

They come with that LA. But I think they can be bought somewhere else.

This is awesome! I can't wait to try it out. Almost seems to easy to use to be real!

I haven't though much about level shifting, but I do have some of the SparkFun voltage converters. www.sparkfun.com/commerce/product_info.php?products_id=8745
The schematic shows 2 channels that can be set to different voltages 5 to 3.3, 5 to 1.6, 3.3 to 2.8, etc .... Maybe I can do some measurements later today.

The circuit I've used mostly as mentioned in the first post is the one below. I just set it on top of the Propeller I want to test.

I've recently added a 6.25MHz crystal to that so there is less dependency on the device under test for clock (this requires a small Spin _xinfreq adjustment). It still relies on the power though.

The Propalyzer2.jpg picture above was an attempt at making a PCB with a QFN Propeller chip. Good size for a DIP40 - not so good for my soldering skills. I would like to see some kind of a PCB that adds value (maybe with level shifter options, etc...) for use with the software.

I really like those easy hook connectors. If I could buy about 1000 of them, I would make a hardware kit :) Regarding Radio Shack alligator clips: those should work too. With any connector, I suggest keeping your wires really short. Stay under 12" (300mm) if possible.

Happy Propellering.

Nice place Hector: Now I know how taps are called in English.

Edit: I thought the LA I have have mosfets as level shifters... but it hasn't. Only 2 series resistors, one capacitor and bias voltage.

The 14th update to Propalyzer is now available.

Version 1.0.1.3 had over 250 downloads. User feedback has been very encouraging.
Version 1.0.1.3 has been removed from the top post; if you really need it, I can provide it.

Based on user feedback, this release allows setting the Clock Frequency used for the sample period.

Also, the source code may be release specifically for non-Windows users experiments if there is interest.
Surely mono supports .net version 2.0 by now :)

Hi jazzed.

Some problems to start it with to big patch to it.
H:\Arbets\_Div Spin Code\-_ HardWare\HardWare\Propalyzer_1010\Propalyzer_1014 - on that path it wil not start.
But if I copy it to Z:\Propalyzer_1014 it is not problem to start it
