Accelerometer (ADXL345)

This script measures acceleration using the widely available ADXL345 Accelerometer, which can measure acceleration up to 16g on 3 axes. The accelerometer on a breakout board is available here:

The data obtained from the accelerometer is published to USER_RAM registers, which can be accessed by any other programs connected to the T-Series device. This allows a program to be doing one task while the device simultaneously obtains the accelerometer data.

The datasheet is extremely useful for determining the setting on the device, such as low-power mode and range (2g, 4g, 8g, or 16g)

The other functionalities of this device, like configurable interrupts, fall detection, and tap detection can be configured just as the range is configured, although these specialized functions are outside the scope of this example.

In the above images, an inexpensive LJTick-LVDigitalIO was used to source the 3.3V needed for the ADXL345. A CB15 was used to expose the EIO4 and EIO5 connections.

This example can be found in our Kipling git repository:
