Thank you Bill and rocketgeek for your replies!!!

I´m going to wait one day more before to make a decision.... smiley-wink


cheers!

Thank you Rob for your comments.  smiley-grin

Rocketgeek, what about your experiences with the USBee SX? I like that you can create your own protocols and it can work as generator.

The Open Logic Sniffer is the best hardware (100 MHz) for the minimum price ($49.95). It uses SUMP logic analyzer client. It´s open source and at the moment it has not the level of the other soft interfaces and doesn´t supports many protocols (as a protocol analyzer).
This client looks good => http://www.lxtreme.nl/ols/
Original client => http://www.sump.org/projects/analyzer/client/

Any experience with it?? I can´t find reviews about it.


Too many options....hehehe    smiley-wink

I´ve found a similar topic in other forum: http://www.rcgroups.com/forums/showthread.php?t=1023934

Zeroplus is better because you have more speed, but size limited.Not an user friendly soft.Limited the CAN bus protocol analyser (for CAN bus based protocols).
USBee looks a very good and allows to add your own protocols.
Saleae has probably the best software interface.

Thank you for your replies.

The prices are:
  • Saleae is 149 euros.
  • LAP-C 16032 is $120.00 (plus an special introductory offer: 2 free additional protocols).
  • USBee SX is $169.
  • Open Logic Sniffer is only 49 euros.

Now Saleae offers a SDK to develop your own app in .NET... From FAQ:
" Is there an SDK available?
Yes, right now we have a low-level data access SDK. It's still in development but email us and we can send you the latest. We're also working in an SDK for making your own protocol analyzers, but this isn't ready quite yet.
"
One good feature, it´s you can have a large capture, although limited to 24 MHz.

LAP C 16032 looks very good.... maybe it´s the best option price vs features. Although, if you want to have more addtional protocols, you have to pay for it. But right now, with the offer you can get the same than the other hardwares.....
I´m not sure if 512 KB of capture memory will be a problem....

USBee SX right now allows create your own protocols.
"The USBee SX Test Pod is a HUGE sample buffer PC and USB based multifunction logic analyzer and digital signal generator in a single compact and easy to use device and includes a powerful bus decoder that shows ASYNC, I2C, SPI, 1-Wire, USB, CAN, I2S, SMBus, Sync Serial, PS/2 and even your own Custom Serial Bus data.."

I´m interested to have CAN bus... Have you tried with Saleae or USBee ?



Graynomad now you have to reply to have again the same posts´ number.... smiley-wink

Hi,

I would like to buy a low cost Logic Analyser. I´ve found these devices:


Any recomendation?? Any experiencie with them?

Thank you!  smiley-wink

Hi,

If you want to use as datalogger, I recommend you to use flow control (RTS and CTS lines). To avoid problems with buffers.
And with DIP2, to test my example, pin 18 is equivalent to pin 10 of VDIP1 (mine). This means, connect it to gnd if you aren´t using flow control.
At the moment, I´ve only done this example. I haven´t problems with the device, but it´s true that I´ve read what you say.

Hi,

It´s based on Hello world example from vinculum, which it´s good commented for a PIC microcontroller.

Basically:
  • VNC1_Confirmation()=> returns 1 if D:\>+CR has been received.
  • VNC1_Sync()=> returns 1 if the sync method was ok. This means send and receive the echo characters ("e" and "E").
  • VNC1_FindDisk()=> return 1 if there is a pendrive connected to the device.

The command while (VNC1_Confirmation()==0); waits until D:\>+ CR has been received. First, I tested with hyperterminal what the vinculum device answer after the commands.


The objetive it´s expand it with flow control (CTS and RTS signals). I´ve used long commands and Serial 3 of Arduino Mega.
When a button connected to pin 9 is pushed, first sync, after look if there is pendrive and open to write igor.txt. The data saved is IGOR and millis() time + CR.
It´s very basic and fool example.

I hope this help you.  smiley-wink

Igor R.

Hi,

I´ve been tinkering with Vinculum chip (VDIP1 board).
http://www.vinculum.com/prd_vdip1.html
At the moment, without flow control....
I´ve based on:
http://www.arduino.cc/playground/Main/UsbMemory
http://www.vinculum.com/downloads.html#vutilities

The pin out of VDIP is:

Pin 1.- 5 volts
Pin 6.- TXD
Pin 7.- GND
Pin 8.-RXD
Pin 10.- GND


My code example with Mega is here. it´s quite fool... only to start with the device  => http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1247331076/0#0


When I connect a pendrive, the device is trying to see any firmware update inside before to start. Is it possible avoid this? Because it´s a long time...


Thank you



Kind Regards,



Igor R.

Hi,

Some time ago, I wrote a RS485 sample code in spanish forum.

I´m going to translate to english asap, while you can see the code here => http://real2electronics.blogspot.com/

ja,ja,ja

I would like KS0107/KS0108 or Toshiba T6963 because it´s easy to implement and there are many info and libraries in internet.
Something like this: http://www.crystalfontz.com/product/CFAG240128L-YYH-TZ

Size: 240x128 or 160x128

But in stead of Yellow/Green led backlight, I would like blue or red backlight. Both would be fantastic!!
Letters-Graph in black and background in blue is a perfect combination!!

Example:






Is it possible change the leds?
