Logic Sniffer client version 0.9.6 beta release

Jawi continues to develop the Logic Sniffer cross-platform client. A beta of the new version 0.9.6 is available to testers. This has the killer new signal display component demoed previously. Jawi’s open source client will soon outclass every commercial offering we’ve ever used. Here’s the change log:  New signal display component is in place! While […]

Inexpensive Sniffer reveals 802.15.4 packet details

Jon used TI’s SmartRF Protocol Packet Sniffer to reveal 802.15.4 wireless packet details: For the last several months my work with the XBee modules from Digi International involved using a logic analyzer to monitor the serial communications to and from the modules so I could measure the times between transmissions and view data streams as […]

AVR based 4 channel mini logic analyzer

This small 4 channel logic analyzer uses a ATmega microcontroller and a Nokia 5110 LCD. It’s able to capture signals only up to about 100Khz, but there is probably some room for improvement. This mini Logic analyzer is a tool for you to watch on LCD the logic transitions 0 or 1 of a digital […]

Logic Sniffer client version 0.9.5 final released

Jawi released the version 0.95 final of his Logic Sniffer client. It has these updates: Client now also runs on Java 7, but remains backward compatible with Java 6 Fixed issues #82, #81, #79, #77, #76, #75, #74, #70 and #40 Use PureJavacomm as experimental serial library instead of RXTX Major cleanups in Tool/Device API […]

Logic Sniffer client: New signal display component

Jawi uploaded a preview of the new signal display component for the Logic Sniffer application. OLS is a java client designed to run on multiple platforms including Windows, Linux, and Mac. You can download this mock from ols.lxtreme.nl, which should run on Windows, Linux and OSX (only the latter is heavily tested ;)). A list […]

Logic Sniffer: Vote for signal display annotation style

Jawi is developing a new version of the Logic Sniffer client app. He’s currently deciding on which style to use for annotation. Help him out by casting your vote in the forum. The OLS client supports the annotating of data to present additional information along with the signal data. For example, many of the decoding […]

Logic Sniffer: Hacking cheap RFID readers

Aaron decided to hack a cheap USB RFID reader, by using the Logic Sniffer to figure out the internal IC protocol. To make it useful for his projects he decided to hijack the internal bus that has the initial RFID decoding. After some poking around he was able to find the UART TX transmitting pin. […]

Logic Sniffer client 0.95b1 beta release

A beta release of Jawi’s Logic Sniffer client version 0.95 is now available. It has these updates: Client now also runs on Java 7, but remains backward compatible with Java 6; Fixed issues #79, #77, #76, #75, #74, #70 and #40; Use PureJavacomm as experimental serial library instead of RXTX; Major cleanups in Tool/Device API […]

Logic Sniffer hack improves signal integrity

Tarloth designed this cool hack to improve signal integrity of the Open Bench Logic Sniffer. Instead of using the standard 1×18 pinheader, he used a dual row 2×18 header. One row is connected to the board, while the other is connected to GND. Unused signal pins are jumpered to GND using the extra header row. […]

Logic Sniffer: Bluetooth wireless connection

There’s an interesting discussion in the forums about enabling the Open Bench Logic Sniffer to work with Bluetooth. The consumer market is being flooded with cheap Android enabled tablets, and it seems like a good idea to use them with the OBLS to make a portable logic analyzer. Pppd is currently working with a BT […]

Logic Sniffer: RC transmitter module design debug

pppd created a removable RC transmitter module based on ATtiny25  with the Logic Sniffer. Annoyed by an uncomfortable RC transmitter design and its stick mode, pppd decided to build a removable RC transmitter. It works by converting the standard RC PPM into the IR signal used by the toy. But first he needed to reverse engineer the original using the […]
