The Kionix Accelerometer Application and Firmware Development Kit provides a simple environment to quickly begin the development of applications and firmware that incorporate Kionix accelerometers. The Development Kit provides a common interface to Kionix evaluation boards. The included software provides an easy-to-use interface for displaying and recording acceleration data. Plus, a graphical register map allows the user to see and change the contents of control registers.
The Silicon Labs development board allows the use of a standard 8051 microcontroller core and a USB interface for PC development/evaluation environments. Additionally, the F340 Adapter Board provides a visual indication (through an LED array) of interrupts (motion and tap) and screen rotation output states for Kionix products that include those functionalities.
Here is a brief description of the applications and utilities supported by the Development Kit:
This application allows the user to monitor data coming from the attached sensor. This data can be saved to a file or viewed in real time. With only two verification steps, the application will display a series of graphs representing acceleration with respect to time for each axis.
This application allows the user to test and calculate the zero-g offset and sensitivity parameters of the accelerometer. Once the accelerometer is properly placed relative to the Earth’s gravity, simple mouse clicks initiate a series of test sequences that result in the display of raw-count data.
This application allows the user to read and write to specific registers of the accelerometer. The registers and their values are all displayed simultaneously on one color-coded grid.
This utility allows the user to test whether the accelerometer has detected motion on any of the axes. Options are available to change the resolution (8-bit or 12-bit), output data rate, high-pass filter settings, WUF_THRESH and WUF_TIMER register values, or mask any of the axes.
This utility allows the user to monitor the orientation of the accelerometer. It can be used to determine whether the accelerometer is in the face-up, face-down, left, right, up or down orientations. Options are available to change the resolution (8-bit or 12-bit), output data rate, TILT_TIMER, TILT_ANGLE, or HYST_SET (hysteresis) register values, or mask any of the axes.
This utility allows the user to detect tap/double-tap events and see the axis and direction in which the events occur. Options are available to change the resolution (8-bit or 12-bit), output data rate, TDT (Tap/Double-Tap) Timer, TDT_H_THRESH, TDT_L_THRESH, TDT_TAP_TIMER, TDT_TOTAL_TIMER, TDT_
The EZ430-C9 is an evaluation board (containing Kionix's KXTC9 accelerometer) which easily plugs into the Texas Instruments eZ430-F2013. The eZ430-F2013 is a complete MSP430 development tool including all the hardware and software to evaluate the MSP430F2013 and develop a complete project in a convenient USB stick form factor.
To facilitate prototype work with Kionix accelerometers, Kionix has created evaluation boards for each accelerometer product. The evaluation boards provide access to the pins of the accelerometer, contain all of the appropriate decoupling capacitors and pull-up resistors, and allow for easy connection into a prototyping system.
