Related Hardware and Initiatives. It is very accurate, as it contains bits analog to digital conversion hardware for each channel. Therefor it captures the x, y, and z channel at the same time. The sensor uses the I2C -bus to interface with the Arduino. The MPU is not expensive, especially given the fact that it combines both an accelerometer and a gyro.

Reading the raw values for the accelerometer and gyro is easy. The sleep mode has to be disabled, and then the registers for the accelerometer and gyro can be read. Invesense the sensor also contains a byte FIFO buffer. The sensor values can be programmed to be placed in the FIFO buffer. And the buffer can invebsense read by the Arduino.

A little more complicated is the ability to control a second I2C -device. It can control, for example, a magnetometer. Invensehse values of inveensense magnetometer can be passed on to the Arduino. Things get really complex with the “DMP”. This DMP can be programmed with firmware and is able to do complex calculations with the sensor values. However, some have used reverse engineering to capture firmware.

This reduces the load mpy the microcontroller like the Arduino. 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 accelerometer and gyro values are called the invrnsense values. This is just as with other accelerometer and gyro sensors. A more sophisticated application is using the DMP to retrieve specific computed values from the sensor. The Short example sketch on this page is a very short sketch that shows all the raw values. Click “Get code” at right, below the sketch, invemsense copy it into a sketch. The Example sketch base code on this page is also just showing the raw values, but it is an attempt to be a complete base for more functions.

See his I2C lib: The pin ” AD0 invensens selects between I2C address 0x68 and 0x That makes it possible to have two of these sensors in a project. Most breakout boards have a pullup or invehsense resistor to make AD0 default low or high. However, someone in the forum mentioned a nice trick:. If the number of pins is a problem, then a shift register or a port expander can be used.

Suppose all AD0 lines are default high 3.

That I2C address is however never used! After that is finished, the Arduino selects another AD0 line, and can use that sensor. So every sensor is used at I2C address 0x68 one by one and 0x69 is never used. This should make it possible to have many MPU sensors in a project. Even more than 10 sensor should be possible.

A sensor with SPI interface is faster. Update March 25 There are a number of “breakout boards” or “sensor boards” with the Invenense The price dropped fast, iinvensense 2. The raw values raises questions in the forums, since the raw values might seem unstable. Below are the raw values of the sensor that I measured, so you can compare them with your own raw values.

The raw values changes a lot due to a number of reasons. The default sensitivity is high, and the sensor returns 16 bits, but the actual valid number of bits is less than 16 bits.

invensennse Since they are 16 bits, a variation of 50 is just a very small variation. The short example sketch is a very short sketch and it shows all the raw values accelerometer, gyro and temperature.

The sketch uses the Arduino functions as much as possible. For now, it is just a simple and basic sketch to get the MPU working.

The I2C -address depends on the AD0 pin of the sensor. If it is connected to ground, the address is 0x There are a few sensor boards with the MPU sensor already soldered on it. The acceleration and gyro values of the sketch are raw values, which are not yet compensated for offset.

The very first acceleration and gyro values after power up are sometimes not valid. A pointer to the data to write. The number of bytes to write. For more info pleae look at this Forum Post. The FIFO buffer is used together with the interrupt signal.

The output of a 5V Arduino can not be used. In that case a voltage divider or level shifter for 3.

Arduino Playground – MPU

The 5V output pins can also be converted in 3. Pullup resistors to 3.

This breakout board must be used with 3. There is no voltage regulator and no I2C -level shifter on the board. The pull-up resistors for the I2C -bus are 10k. A schematic is not provided. It can be used with 3. This invvensense board has a voltage regulator. It is preferred to apply 5V to the VCC pin of the sensor board.

The board has pull-up resistors on the I2C -bus. The value of those pull-up resistors are sometimes 10k and invvensense 2k2. The 2k2 invebsense rather low. If it is combined with other sensor board which have also pull-up resistors, the total pull-up impedance might be too low. Some GY modules have the wrong capacitor or a bad capacitor and that results into a high noise level: A data visualiser that makes life easier when starting out. Also includes an extended version By http: So it can be used with 3.

The pull-up resistors are sometimes 10k and sometimes 4k7. If they are 10k, two extra pull-up resistors of 10k to the 3. The pull-up resistors of the I2C -bus are 4k7. It is actually a GY breakout board. A sensor invensensd with the MPU and a magnetometer and barometer. The sensor board contains a voltage regulator, so it can be used with 5V.

There seems to be also a level shifter on the board for the I2C -bus. The pull-up resistors for the I2C -bus seems to be 2k2, which is rather low. The header is on the right with the pins in this order: On the back are 60050 solder jumpers, one of them for AD0.

In a new MPU appeared without any invensenxe or code. It is almost equal to the GY board. There is a voltage regulator on the board for 3. Because of the voltage regulator, connect 5V to the VCC of this sensor board. Start address, use a define for the register.
