Feb 28, 2001 — by LinuxDevices Staff — from the LinuxDevices Archive — 4 views

Davie, FL — (press release excerpt) — Maple Signal Processing announced the DAQStick line of embedded signal processing cards. The first model, DAQ6854 is a compact, low power board based on the Motorola DragonBallVZ microcontroller and high speed Texas Instruments TMS320C541xx Digital Signal Processor. The DAQStick line runs the freely available uClinux on the DragonBallVZ allowing for cross development on any Linux platform. The C5416 is supported by TI's Code Composer line of development and debugging tools.

Maple Signal Processing designed the DAQStick to be adaptable to a wide variety of OEM and user applications. The DAQStick is “Net” ready providing for the design of systems that are easily field upgradable due to its support for http, telnet, ftp, and nfs. Applications for the DAQStick include: Real Time Control, Data Logging, Acoustic Processing, Remote Telemetry, and a host of others.
