That I2C address is however never used! The value of those pull-up resistors are sometimes 10k and sometimes px. The number of bytes to write. This reduces the load for the microcontroller like the Arduino.

The I2C -address depends on the AD0 pin of the sensor. A sensor board with the MPU and a magnetometer and barometer.

There is a voltage regulator on the board for 3. However, someone in the forum mentioned a nice trick:. Since they are 16 bits, a variation of 50 is just a very small variation. This is just as with other accelerometer and gyro sensors.

The board has pull-up resistors on the I2C -bus. The values of the magnetometer can be passed on to the Arduino.

The accelerometer and gyro values are called the “raw” values. The sensor values can be programmed to be placed in the FIFO buffer. The default sensitivity is high, and the sensor returns 16 bits, but the actual valid number of bits is less than 16 bits.


Click “Get code” at right, below the sketch, and copy it into a sketch. The Example sketch base code on this 6000aa is also just showing the raw values, but it is an attempt to be a complete base for more functions. Suppose all AD0 lines are default high 3. Even more than 10 sensor should be possible. So every sensor is 600a at I2C address 0x68 one by one and 0x69 is never used.

Arduino on other Chips. Pullup resistors to 3. The sketch uses the Arduino functions as much as possible. The FIFO buffer is used together with the interrupt signal.

This breakout board must be used with 3. This DMP can be programmed with firmware and is able to do complex calculations with the sensor values. In that case a voltage divider or level shifter for 3. The sleep mode has to be disabled, and then the registers for the accelerometer and gyro can be read. A schematic is not provided. There is no voltage regulator and no I2C -level shifter on the board.


It can be used with 3. The 2k2 is rather low. Update March 25 There are a few sensor boards with the MPU sensor already soldered on it. So it can be used with 3. If the number of pins is a problem, then a shift register or a port expander can be used. A sensor with SPI interface is faster. If it is combined with other sensor board which have also pull-up resistors, the total pull-up impedance might be too low. It is preferred to apply 5V to the VCC pin of the sensor board.


On the back are three solder jumpers, one of them for AD0. That makes it possible to have two of these sensors in a project. 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.

The pull-up resistors for the I2C -bus are 10k. A more sophisticated application is using the DMP to retrieve specific computed values from the sensor.

The pin ” AD0 ” selects between I2C address 0x68 and 0x The header is on the right with the pins in this order: The very first acceleration and gyro values after power up are 6000 not valid. Reading the raw values for the accelerometer and gyro is easy. Also includes an extended version By http: Most breakout boards pd a pullup or pulldown resistor to make AD0 default low or high. However, some have used reverse engineering to capture firmware.

It is almost equal to the GY board.

In a new MPU appeared without any name or code. Below are the raw values of the sensor that I measured, so you can compare them with your own raw values.

The Short example sketch on this page is a very short sketch that shows all the raw values. The playground is a publicly-editable wiki about Arduino. After that is finished, the Arduino selects another AD0 line, and can use that sensor.
