The EVAL-ADXL362-ARDZ shield illustrates the functionality of the ADXL362 - an ultralow power, 3-axis MEMS accelerometer.
The ADXL362 is capable of measuring dynamic acceleration (resulting from motion or shock) as well as static acceleration (gravity). It provides 12-bit output resolution and has three operating ranges, ±2 g, ±4 g, and ±8 g. Additional useful features include an on-chip, 12-bit temperature sensor accurate to ±0.5°, motion triggered wake-up functionality, and and several activity detection modes which makes is ideal for portable low-power instruments.
The EVAL-ADXL362-ARDZ Shield is designed in Arduino Uno R3 format which makes it suitable to used with both Arduino Due (e.g. EVAL-ADICUP360 based board) and Arduino Uno R3 base boards.
The EVAL-ADXL362-ARDZ board has a large capacitor(C18) on the board which holds charge for the LCD screen. When power cycling the system, you must wait approximately 5 seconds to allow enough time for the capacitors on the EVAL-ADXL362-ARDZ board to fully discharge. This is a power requirement for the ADXL362, which notes in the datasheet that the power rail must come all the way back down to 0V before powering back up.
This chapter describes the hardware and provides for download the schematics and the layout.
The EVAL-ADXL362-ARDZ Shield has four jumpers to increase flexibility when stacking systems together. Each jumper and it's purpose is described below.
