Open Logic Sniffer bootloader rescue

Some Logic Sniffers shipped without a bootloader, and will require a firmware flash before USB upgrades are possible. This post describes how to program the OLS bootloader using a Bus Pirate. It’s also possible to program the bootloader with a PIC programmer like a PICkit or ICD2. If you don’t have a Bus Pirate or […]

“Logic Analyzer in a Day” Experts’ Challenge

Development board manufacturer Opal Kelly has invited three FPGA experts to design logic analyzers. Each participant has 8 to 10 hours to complete a design, the final designs will be posted online. The analyzer will be built with Opal Kelly’s modules and software development kit, but there might be some interesting takes on a common […]

Ril3y’s new Open Logic Sniffer case

Ril3y sent photos of a new laser-cut case for the Open Logic Sniffer. This case isn’t available yet, but we’ll keep you updated. Ril3y also sells a popular laser-cut case for the Bus Pirate. You can order the OLS at Seeed Studio for $45, including worldwide shipping. Don’t forget that Seeed now has probe cables […]

Windows Logic Sniffer client update

There’s a new version of raphihouri’s Windows/.Net client for the Logic Sniffer.  This update incorporates suggestions from the forum. Fixed: – glitches at the beginning of trace. – invalid trace returns in demo mode. – window resizing stretches the trace. – channel and trigger numbering and mapping. Added/changed: – Buffer size is now a combo […]

Logic Sniffer: Major update, testers needed

This is an old version, see the latest version on the documentation wiki. This week there should be a major update for the Open Logic Sniffer that fixes a communication problem on some boards when alternate bitstreams are loaded. This fix implements the SPI connection between the PIC and FPGA.  The update improved sample download […]

Bus Pirate PIC 18F24J50 programmer update

We’ve been working on a PIC 24F programmer for the Bus Pirate, now we’re working on PIC18F24J50 support. PIC 24Fs and the 18F ‘J’ parts can be programmed directly by the Bus Pirate because they are 3.3volt chips that don’t require a separate programming voltage. 18FJ support means the Bus Pirate can reprogram any Logic […]

Sigrok: Open source logic analyzer client

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 […]

Logic Sniffer FPGA bitstream/ROM update

This is an old version, see the latest version on the documentation wiki. The Logic Sniffer stores the FPGA (IC3) bitstream in a flash ROM chip (IC2). The PIC microcontroller (IC1) can update the bitstream from a computer using the multi-platform pump-loader application. This feature lets us release FPGA design updates with new features and […]

Logic Sniffer mention in Nuts & Volts

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Logic Sniffer got a mention in a Nuts & Volts article titled Reading and Writing an EEPROM Using the […]

Logic Sniffer quick start video

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. Logic Sniffers are starting to arrive worldwide, and the Gadget Factory has a quick start video to get you going […]

Logic Sniffer probes available next week

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. We’ve got a long-awaited update on probe cables for the Open Logic Sniffer. Word from Seeed is that they should […]

Open Logic Sniffer assembled, in testing

Openbench Logic Sniffer is an open source logic analyzer. It’s designed to support the SUMP logic analyzer software at the lowest possible cost. This project is a collaboration between the Gadget Factory and Dangerous Prototypes. The Open Logic Sniffer returned from the factory. It will be programmed and tested soon. Seeed makes the rather ambitious […]

Open Logic Sniffer preorder update

This is the manufacturing prototype of the Open Logic Sniffer logic analyzer. Parts are all in-house at Seeed Studio. Procurement is usually the most hazardous and delay-fraught phase of a preorder. Assembly, which will begin by Monday, is usually pretty quick. After assembly, the boards will be inspected, programmed, tested, and shipped to preorder participants. […]

Sigrok: Open source logic analyzer client

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 […]
