The output of a 5V Arduino can not be used. That I2C address is however never used!

Because of the voltage regulator, connect 5V to the VCC kpu this sensor board. This is just as with other accelerometer and gyro sensors. The sketch uses the Arduino functions as much as possible. See his I2C lib: The acceleration and gyro values of the sketch are raw values, which are not yet compensated for offset.

In a new MPU appeared without any name or code. The Short example sketch on this page is a very short sketch that shows all the raw values. There is no voltage regulator and no I2C -level shifter on the board.


The 2k2 is rather low. The DMP is even able to do calculations with the sensor values of another chip, for example a magnetometer connected to the second sub – I2C -bus.

If it is connected to ground, the address ls 0x The price dropped fast, only 2. Click “Get code” at right, below the sketch, and copy it into a sketch. Below are the raw values of the sensor that I measured, so you can compare them with your own raw values. It is preferred to apply 5V to the VCC pin of the sensor board. The number of bytes to write. The FIFO buffer is used together with the interrupt signal. Sources for Electronic Parts. A pointer to the data to write.

The sleep mode has to be disabled, and then the m;u for the accelerometer and gyro can be read.

Update March 25 Mmpu that is finished, the Arduino selects another AD0 line, and can use that sensor. The pin ” AD0 ” selects between I2C address 0x68 and 0x The value of those pull-up resistors are sometimes 10k and sometimes 2k2. Board Setup and Configuration. A data visualiser that makes life easier when starting out. That makes it possible to have two of these sensors in a project. A sensor with SPI interface is faster. So every sensor is used at I2C address 0x68 one by one and 0x69 is never used.


This reduces the load for the microcontroller like the Arduino.


The header is on the right with the pins in this order: The 5V output pins can also be converted in 3. The board has pull-up resistors on the I2C -bus. The sensor uses the I2C -bus to interface with the Arduino.

However, someone in the forum mentioned a nice trick:.


The playground is a publicly-editable wiki about Arduino. It can be used with 3.

This DMP can be programmed with firmware and is able to do complex calculations with the sensor values. But the sensor also contains a byte FIFO buffer.

It can control, for example, a magnetometer. A little more complicated is the ability to control a second I2C -device.
