Start Playing With Your Papilio Pro Logic Analyzer!

https://youtu.be/D7FWUJoVaIc

If right now you are kind of what is this guy talking about? Then you should check this and learn one of the almost infinite applications of a Papilio Pro.

Today, we bring an article that explains one use for your brand new Papilio Pro Logic Analyzer. This is to capture the communication via I2C between a Bus Pirate and the fuel gauge chip on the Fuel Tank BoosterPack.

This article is part 2 of a series of 3. Read article one to get all the details about setting up the project and then start playing with your Papilio Pro Logic Analyzer to capture all the traffic. Enjoy!

Want a Logic Analyzer?? Then just get a Papilio!

https://youtu.be/pqCo8yAhLhQ

Not long ago we published an article about using an Arduino UNO as a logic analyzer. As it couldn´t be otherwise, you can also do the same with a Papilio. And guess what? The Papilio-based logic analyzer is more powerful. No hype, just real numbers. You can achieve 32 channels, at 200 MHz, while you can only get up to 4 MHz with the Arduino UNO.

Fine, we have to admit that there might be a minor drawback. Papilio works with signals at 3.3 V. Easy to solve, all you need to do is add a level translator and then you are ready to play with 5V signals as well!

Enjoy this great tutorial and have fun with your logic analyzer. Read the full article and you will know why you can make such a great logic analyzer from your Papilio!

Do you have an Arduino UNO? Then you have a logic analyzer!

arduino_as_logic_analyzerThis tutorial shows, step-by-step, how to turn your Arduino UNO into a 6 channel SUMP.

This logic analyzer is able to sample signals with a speed varying between 4 MHz and 10 kHz. Best results are obtained below 1 MHz. Above this mark, there is too much of a lag between the trigger detection and the sample start.

Get hands on and have fun with your recently discover logic analyzer!

OpenBench Logic Sniffer 3.07 “Demon” Core Release!

Download the OpenBench Logic Sniffer 3.07 “Demon” core Release from the new Logic Sniffer information portal.

 

There has been a lot of new progress with the OpenBench Logic Sniffer. “Dogsbody” has contributed an exciting new Verilog core that adds some significant improvements:

 

3.07 OpenBench Logic Sniffer Release

  • 3.07 FPGA “Demon” Core
    • Fix for 200Mhz sampling in “Demon” Core
  • 3.0 PIC Firmware
    • SPI speed increase
    • Fix for Winbond read issue
  • 0.9.3 SP1 Jawi OLS client
    • Bug fixes

 

3.06 FPGA “Demon” Core Release

  • RLE works correctly for all memory depths.
  • HP 16550a Advanced triggering mode. (The client does not support this yet, but the Verilog core supports triggers just like the HP 16550a!)
  • Meta tags inside the FPGA core allow the client to determine the version running on FPGA.
  • Jawi’s client “0.9.3.1” fixes RLE issues, adds JTAG decoder, and 1-Wire decoder.
  • Version 2.6 of the PIC firmware increases SPI transfer speed. The difference is noticeable, this release is named “Demon” because it is a speed demon.
  • OLS Upgrader works for both Windows and Linux now. A simple menu based GUI steps you through upgrading your OLS.

  • Main window (light theme) with scope.
  • Main window (light theme) with measure tooltip.
  • Main window (dark theme).
  • Measurement tool.
  • OLS general settings.
  • OLS trigger settings.
  • General preferences.

How-to debug internal FPGA Logic with the $50 Openbench Logic Sniffer.

This tutorial shows how to use the $50 OpenBench Logic Sniffer to debug internal FPGA logic. Debugging internal FPGA logic can be pretty challenging and time consuming, a lot can be done using simulation but when you have logic that interacts with the outside world debugging can come to a grinding halt. The traditional solution is to use the $500+ Chipscope Pro software, but for many this is just too expensive. This tutorial shows a cheap and effective way to get a look at what is going on inside your FPGA.

 

The FPGA development board used in the screencast is Gadget Factories Open Source Papilio One board. Think of the Papilio One as the “Arduino” of FPGA development boards.

OpenBench Logic Sniffers hot off the Pick and Place machine.

Open Bench Logic Sniffer

Gadget Factory is now manufacturing and selling OpenBench Logic Sniffers! We just finished programming the design into the pick and place and have the first batch tested and ready to go. For those who have been waiting for the OLS to be stocked at Seeed Studio, wait no longer.

 

The OpenBench Logic Sniffer is a low cost USB Logic Analyzer that was developed by Gadget Factory and Dangerous Prototypes. Manufacturing and selling them ourselves allows Ian and I to make a couple extra dollars per board. Ordering directly from us, the developers, is always appreciated.

 

Boards will continue to be sold and manufactured by Seeed Studio, but now North America has a quicker shipping option with Gadget Factory.

 

To purchase your own OpenBench Logic Sniffer for $49.99 visit the Gadget Factory product page.
