Blackhawk launches new I²C bus analyzer

Blackhawk has released Blackhawk Scribe , a new I²C bus analyzer, the company's first product introduction outside of its core JTAG emulation-based products. Combining a rich feature set with an affordable price, Scribe is well suited for both entry-level and complex I²C applications.

The Scribe is designed for embedded software and firmware development, hardware debug, and system performance verification. Developers are able to monitor and log I²C bus traffic in real-time. All decoded I²C protocol data is displayed in an easily comprehended format. Hardware debugging features include exercising the I²C bus and communicating with its peripheral components, which provides a convenient interface to “peek” and “poke” device registers while simultaneously watching traffic on the bus. In-System Programming (ISP) capabilities facilitate programming and verification of I²C-compatible EEPROM devices using the Scribe's single-click interface to display and update memory contents.
