The Attach demo consists of a 3 board stack up using the Arduino connectors on the Kinetis FRDM-KL26Z board. The demo runs from a Li Ion polymer battery and consists of 1x FRDM-KL26Z board, 1x FRDM-BATT board (including battery and loudspeaker) and 1x Arduino LCD touch screen board. The code builds using either CodeWarrior V10.6 or IAR EWARM V7.20.2. The software uses eGUI to drive the Arduino LCD and runs demos for the following Sensors - FXOS8700 (combined 3-axis Accelerometer and Magnetometer) and FXAS21000 (3-axis MEMs Gyro). The demo also includes 7-element eCompass code for which full source code is available. Finally, the board also uses the MC34673 1.2A charger for Li Ion batteries, charging is accomplished via either of the USB ports on the FRDM-KL26Z. All datasheets, schematics, source code and bill of materials are included in the zip archive. NOTE: software update which now includes 10-element eCompass software and Kalman filtering code creating a far more accurate eCompass solution.
