GENERAL DESCRIPTION
It is often a time saver in hardware development to make progress
on the firmware and the hardware simultaneously. The challenge is
that it proves difficult to develop firmware before the hardware
exists. The
i
MEMS® ADXL345 development board is an easy-
to-use tool that facilitates prototyping by providing a platform
that can be duplicated in the final application. Additionally, the
development board can be configured as a datalogger and can
be used to gather data for refining algorithms, tuning thresholds,
and generally familiarizing oneself with accelerometer data.
Two AAA batteries power the development board and thus it
integrates seamlessly into portable applications. Communications
and processing is done by an ARM7-based
ADuC7024
micro-
controller, and the interface provided is fully reprogrammable.
Moreover, all ADuC7024 pins are broken out into headers to
facilitate design of compatible expansion boards. Data is logged
onto a MicroSD memory card, providing essentially unlimited
memory capacity and operating system versatility. Data is stored in
a text file; therefore, there is no need to install any software to
operate the board or read data. Software is provided to assist
with programming the board.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
