Power consumption scales automatically with bandwidth. A in standby mode at VS = 2. User-selectable resolution. And it supports output data rates ranging from 10Hz to. The sensor consists of a micro-machined structure on a . Datasheets , EagleCAD PCB files and Fritzing object available in the product tutorial . ADXL3, 3-Axis Digital Accelerometer with 13-Bit Resolution. EVAL-ADXL345Z-DB datasheet link, BOARD EVAL FOR ADXL3.
Digital output data is formatted as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. Libraries for both communication protocols are provided below. AXIS ACCELEROMETER ADXL345. Bandwidth selectable via serial command. Gaming and pointing devices.
The ADXL3is well suited to measures the static . This new version adds standoff holes as well as an extra decoupling capacitor. The datasheet shows all of the registers ADXL3up to detect a single and double tap event. MEMS – Micro Electro-Mechanical Systems.
The Adafruit_ADXL3driver takes advantage of I2C mode to reduce the total pin count required to use the sensor. More information on the ADXL3can be found in the datasheet : . Instead of a mux you could use additional pins on the Arduino for a SoftTWI bus. Last, you can connect more modules on an SPI bus as a . The PmodACL utilizes Analog Devices ADXL3to provide high resolution acceleration changes including inclination changes of less than 1. Interfacing with the Pmod. Triple Axis Accelerometer Breakout – ADXL3from Sparkfun contains the Analog Device ADXL3sensor.
This version of the ADXL3adds standoff holes as well as an extra decoupling capacitor. ADXL3will give your projects ability to sense the static acceleration of gravity in tilt-sensing applications plus dynamic acceleration resulting from motion or shock. Lets look the main Features: Supply Voltage: . Jump to: navigation, search.
PIC18F25K(electrical characteristics, page 441) says a high level on a port with IIC should be above 0. If your Vdd is 5v then I calculate you need a signal of 3. Perhaps the intermittent nature of your problem is something to do with this. Per the data sheet , using SPI is more complicated because another device on the same bus could do something that looks like an I2C start command while CS is high, so they recommend adding external components . For that, you need to send a second (dummy) byte, during which the ADXL3will send your data back (see data sheet , page 16). Please see the ADXL3datasheet for further specifications and features. Most development environments provide a 3. This diagram is an IIC connection method suitable with Arduino UNO.
And if you want to use SPI interface, please refer to ADXL3datasheet for more info. Notice: Before you got this sensor, we have tested it to ensure that the sensor is working right. Sometimes there might be a small offset of the sensor, but it is within the acceptable error range.
Warning: wrong operation can cause danger.
