USB IR Toy: WinLIRC, irPyton updates

July 13, 2010 in Infrared toy, infrared by Ian | No comments

WinLIRC, the Windows version of the popular LIRC PC remote control decoder, has seen a spurt of development after 4 years of no activity.

The updated version uses a new plugin system that should be able to support the USB IR Toy’s irman decoder mode and rawIO modes. We’re also adding a new mode that gives the actual duration of each change in the remote signal.

Development continues on the cross-platform Python GUI for the IR Toy. See the latest build images and source code.

The USB IR Toy is $20, including worldwide shipping.

Open source logic analyzer software

July 2, 2010 in logic analyzer by Ian | No comments

We woke up in a strange world where everyone knew about a new logic analyzer frontend for the Logic Sniffer, except us.

LogicAnalyzer is a framework as well as an application to operate a PC based logic analyzer. It’s built using the Eclipse RCP and designed with extensibiliy in mind. Integrating devices, providing tools or creating completely new functionality is easy.

Sigrok: Open source logic analyzer client

May 21, 2010 in Bus Pirate, logic analyzer, utilities by Ian

We previously posted the Sigrok open source logic analyzer client.  They’ve done a lot of work and it now supports the Saleae Logic, EE Electronics XLA/ESLA100, and ASIX SIGMA. Open Logic Sniffer support is in progress, which will enable Bus Pirate support at the same time.

The Logic Sniffer is $45, including worldwide shipping. The Bus Pirate is available at Seeed Studio and Adafruit Industries.

Sigrok: Open source logic analyzer client

March 19, 2010 in logic analyzer, utilities by Ian | 5 comments

Bert tipped us to the Sigrok open source logic analyzer client. Sigrok is a multi-platform client that aims to support most common logic analyzer hardware. It currently only supports the Saleae Logic, but Open Logic Sniffer support is in progress.

Preorder an Open Logic Sniffer for $45, including worldwide shipping. The OLS should start shipping in April.

SparkFun's Bus Pirate

December 22, 2009 in Bus Pirate by Ian | 9 comments

Months ago SparkFun mentioned that they were working on something similar to the Bus Pirate. We asked them to please consider using the Bus Pirate design because it already has a bunch of features, and it’s in the public domain.

Today we received a prototype of the SparkFun Bus Pirate. SparkFun is the fourth company to sell Bus Pirate hardware, a group that already includes an eBay seller, Fundamental Logic, and Seeed Studio.You might call this the Arduino-fication of the Bus Pirate.

It’s awesome that the Bus Pirate is becoming a popular, widely available prototyping tool. Hopefully SparkFun’s exposure gives a lot more people the chance to use one. Of course, we’d prefer you buy a Bus Pirate at Seeed Studio because each sale directly funds the development of this open source project.

We give our impressions of the SparkFun hardware after the break.

Open source logic analyzer update

December 17, 2009 in logic analyzer by Ian | 7 comments

A few months ago we started working with the Gadget Factory to build an open source logic analyzer. After a very successful collaboration, we’re almost ready to order the first PCBs. Click here for a large PCB image [PNG].

The draft device has 16 buffered (5volt tolerant) input channels, and 16 unbuffered I/O channels on a wing header.  The PC connection is USB 2.0 with a PIC18F24J50 microcontroller. Both the PIC and the FPGA firmware will be USB upgradable.

You can follow our most recent progress in the forum. Uwe’s block diagram of the final design follows.
