Adxl345 turn on arduino i2c example code#

This code is designed to work with the ADXе…ѓ45_I2CS I2C Mini Module available from. Use it any way you want, profit or free, provided it fits in the licenses of its associated works. (Please add the Wire library, along with the ESP8266 library to the Arduino IDE) Thanks to Sparkfun, hereвЂ™s an edited version of their example which will work with the above. To use the ADXе…ѓ45 in I2C (One wire mode) you need to connect the pins as follows (as before, you can hook SDA/SCL to whatever pins you prefer): Unfortunately most of the off the shelf libraries IвЂ™ve seen assume you are using an Arduino and hard code the digital outputs вЂ“ this is entirely arbitrary, you are able to use whatever pins you have available to you. In most configurations you can connect it directly to the IC without any additional circuitry. I was looking at theADXе…ѓ45 I2C accelerometer example and did not find a wiring.

The ADXе…ѓ45 only requires two IO pin from the ESP, plus power. The ADXе…ѓ45 is a small, thin, low power, 3-axis accelerometer with high. and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. It is also operates at 3.3 volts which makes it a perfect match for the ESP microcontroller! The ADXе…ѓ45 is a small, thin, low power, 3-axis accelerometer with high. WhatвЂ™s particularly great about the IC is you can interface either using I2C or SPI вЂ“ both of which the ESP supports. In short the ADXе…ѓ45 is an ultra low cost accelerometer which can be used to measure, err, acceleration in three axis. Serial.print(acc, 3) Serial.print(' ') Serial.print(acc, 3) Serial.print(' ') Serial.Information around the ADXе…ѓ45 Accelerometer is rather sparse online so I wanted to make a quick blog post for those of you who are wanting to have a play with this very cool IC.
