This module integrates the sensor MMA7455L (produced by Freescale), able to detect the movement on three axes, and then in every direction. The chip offers the possibility to select three different sensitivity (± 2g, ± 4g, ± 8g) and makes available, on an SPI bus and the I ² C-Bus, the data detected by allowing a more easily read by a microcontroller. There are also two programmable interrupt lines to communicate a certain event, or to perform one or more actions when it detects a certain acceleration or when the module is stopped.

Here’s a demo of the MMA7455L 3-axis accelerometer in SPI mode using the Bus Pirate. The MMA7455L has:

  • 2/4/8g selectable measurement range
  • 10bit or 8bit output
  • force and pulse detection with interrupt
  • I2C and SPI interface
  • 3.3volts

MMA7455L is an inexpensive 3-axis accelerometer with adjustable measurement range of 2/4/8g. It can communicate with microcontrollers through an SPI or I2C interface. Features are:

  • 2/4/8g selectable
  • 10bit or 8bit output
  • force and pulse detection with interrupt
  • I2C and SPI interface
  • 3.3volts
