Does anyone have experience using the ADXL337BCPZ-RL7 acceleration chip? Code or libraries?
The ADXL337 is an analog output accelerometer. It’s cheap, but I would go with one of the SPI output devices like the ADXL362 which has a Particle library.
The LIS3DH also has a well-tested library and can be used in both I2C and SPI modes.
There are lots of accelerometers and libraries of course, but I mention those two in particular because the Particle InternetButton uses the ADXL362 and the Particle AssetTracker (v1 and v2) use the LIS3DH.
