PS-MPU-6000A-00v3.4 Datasheet.pdf

The value of those pull-up ;s are sometimes 10k and sometimes 2k2. A more sophisticated application is using the DMP to retrieve specific computed values from the sensor. 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.

The 2k2 is rather low. The MPU is not expensive, especially given the fact that it combines both an accelerometer and a gyro. The sketch uses the Arduino functions as much as possible. A sensor with SPI interface is faster.

If the number of pins is a problem, then a 60000a register or a port expander can be used. If they are 10k, two extra pull-up resistors of 10k to the 3. If it is connected to ground, the address is 0x The sensor uses the I2C -bus to interface with the Arduino. The output of a 5V Arduino can not be used. If it is combined with other sensor board which have also pull-up resistors, the total pull-up impedance might be too low.

The very first acceleration and gyro values after power up are sometimes not valid. On the back are three solder jumpers, one of them for AD0. It can be used with 3. It can control, for example, a magnetometer. After that is finished, the Arduino selects pps AD0 line, and can use that sensor. The playground is a publicly-editable wiki about Arduino. In a new MPU appeared without any name or code.

The acceleration and gyro values of the sketch are raw values, which are not yet compensated for offset.

Some GY modules have the wrong capacitor or a bad capacitor and that results into a high noise level: It is actually a GY breakout board. The header is on the right with the pins in mpy order: A pointer to the data to write. A schematic is not provided. Reading the raw values for the accelerometer and gyro is easy. Since they are 16 bits, a variation of 50 is just a very small variation. The number of bytes to write.

A data visualiser that makes life easier when starting out.

Arduino Playground – MPU

Therefor it captures the x, y, and z channel at the same time. The sensor values can be programmed to be placed in the FIFO buffer. This reduces the load for the microcontroller like the Arduino.

So every sensor is used at I2C address 0x68 one by one and 0x69 is never used. This is just as with other accelerometer and gyro sensors.

Below are the raw values of the sensor that I measured, so you can compare them with your own raw values. Arduino on other Chips.

It is preferred to apply 5V to the VCC pin of the sensor board. The pin ” AD0 ” selects between I2C address 0x68 and 0x For now, it is just a simple and basic sketch to get the MPU working. 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.

Board Setup and Configuration. Pullup resistors to 3. It is almost equal to the GY board. However, someone in the forum mentioned a nice trick:. Things get really complex with the “DMP”.

This breakout board must be used with 3. A sensor board with the MPU and a magnetometer and barometer. But the sensor also contains a byte FIFO buffer.

There is no voltage regulator and no I2C -level shifter on the board. Start address, use a define for the register.

The sleep mode has to be disabled, and then the registers for the accelerometer and gyro mup be read. In that case a voltage divider or level shifter for 3.
