IMU Framework is to simplify the development of projects based upon the most powerful and new consumer grade inertial, magnetic and pressure sensors. The main application of Free. IMU is orientation sensing: by reading the data from the various sensors is possible to compute precisely the orientation of Free. IMU in the space. Recent boards also feature an high resolution barometer allowing to precisely track the device altitude. This can be useful in many applications: human- computer interaction device prototyping, flying machines, robots, human movement tracking and everywhere orientation sensing is a key aspect. As Free. IMU breakout the sensors interrupt pins, it's also possible to detect per axis single and double taps, free fall as well as activity or inactivity. This makes Free. IMU a very good choice for Human- Computer devices prototyping. Interrupts pins are also very useful if you are into interrupt based reading of the sensors, useful to develop high frequency interrupt based sensor reading. Video presentation of Free.

IMU versions. Free. IMU version 0. WARNING: Discontinued due to the phasing out of the HMC5. Free. IMU v. 0. 1 is the simplest Free. IMU available. It contains the ADXL3. ITG3. 20. 0 gyroscope and the HMC5. F capacitor to help keeping the power to the sensors stable. It doesn't have any voltage regulator nor any level translator so it needs to be connected to a 3. V power source and the I2. C level signals have to be 3. V. When used on a 5. V microcontroller, an I2. C level converter and a voltage regulator are needed. Free. IMU version 0. WARNING: Discontinued due to the phasing out of the HMC5. Free. IMU v. 0. 2 has the same sensors (ADXL3. ITG3. 20. 0 and HMC5. I added an integrated voltage regulator (MIC5. PCA9. 30. 6). With these components it's extremely simple to use Free. IMU v. 0. 2 on 5. V boards like 1. 6MHz Arduinos, just connect Free. IMU to the 5. V, GND, SDA and SCL on Arduino and you are ready to go! IMPORTANT: in version 0. The drill hole should have been 0. Consequence of this is that only rounded pins will fit inside the drill and standard squared pins won't fit. This is not really a problem as the big oval pad makes actually possible to use 9. The Kicad sources above and the gerbers marked with "Fixed" have this issue fixed. However they haven't been tested on production so double check them before send them to fabrication. Free. IMU version 0. Free. IMU version 0. ADXL3. 46 as accelerometer and the HMC5. L as magnetometer. The gyroscope is still the ITG3. Free. IMU v. 0. 3 integrates a voltage regulator (MIC5. PCA9. 30. 6) as well as all the pullups resistors needed. Free. IMU version 0. Free. IMU v. 0. 3. Free. IMU v. 0. 3. There have been some corrections in the silkscreen and the footprint of the HMC5. L have been made slightly bigger to make assembly easy. Everything else is just as in Free. IMU v. 0. 3. Free. IMU version 0. 3. Free. IMU 0. 3. 5 is a small (2. IMU MARG sensor featuring the BMA1. ITG3. 20. 0 gyroscope and the HMC5. L magnetometer. Free. IMU 0. 3. 5 also has two additional subversions, Free. IMU 0. 3. 5_MS which features the MS5. BA high resolution pressure sensor and the Free. IMU 0. 3. 5_BMP which features the BMP0. Free. IMU v. 0. 3. MIC5. 20. 3) allowing you to plug it from 3. V3 to 1. 6V providing you 8. A of current which you can use to chain it to other 3. V3 sensors or devices. By using the MIC5. Tantalum is not a good idea socially and environmentally. The board has integrated 2. K2 pullups resistors (which can be enabled or disabled by means of a solder switch) but doesn't have an integrated logic level converter. We decided to not include the LLC (which is present in my Free. IMU v. 0. 2 and v. In fact, given a properly configured software, it's a redundant part. Moreover the upcoming development of many 3. V3 based control boards (eg: Multipilot 3. LLC not a very far- seeing choice. The IMU board is however compatible with my LLC board which can be stacked above the IMU, so that you can easily add the LLC protection keeping the amount of additional wires at the minimum. The board, a part from the usual power and I2. C connectors, breaks out the interrupt pins for all the three sensors. This should empower software developers to design interrupt based sensor reading and sensor fusion algorithms (opposed to the currently common polling based approach) which should provide possibility to shorten the cycle path of our algorithms. Free. IMU library. Free. IMU can be easily used on Arduino compatible boards using the Arduino Free. IMU library which implements sensor fusion MARG orientation filter enabling you to do easy and straightforward orientation sensing. Free. IMU library - 2. Use Arduino 1. 0. IDE or later version.

In order to use them, Download and install Processing. Copy the folders within the processing folder of the Free. IMU library archive into your Processing sketchbook. Remember to change the Serial port address in the Processing code to match the address used by arduino on your system. Ports to Other platforms. Free. IMU library on PIC 2. Hari Nairhair [dot] nair [at] gmail [dot] com. Author notes: 1. assumes a 6. MHz crystal is attached and x. PLL internally, so Fosc = (6x. Mhz 2. trivial to use the internal FRC oscillator, instead of FNOSC_PRIPLL in the configuration words, use FNOSC_FRCPLL. This will give you Fosc = (8x. MHz, but of course with less precision. This does slow down the sampling rate. Without the quaternion print, the code completes in less than 1. S, so the sampling rate is exactly 1. Hz as set by the timer. Free. IMU library on NXP LPC1. Cortex m. 3 processor by Hari Nairhair [dot] nair [at] gmail [dot] com. More details and possibility to contact the author on the Free. IMU community development forum. Have you ported the Free. IMU library to other platforms? Please let me know and I'll list your work here! Calibration. A calibration GUI application is available. The software is currently in alpha state, however many people are already using it. The calibration, when properly executed, drastically improve the orientation sensing performance of the Free. IMU framework. If you are experiencing drifting or inconsistent results, your sensors may need to be calibrated using the Calibration GUI. Community. There is now a Free.
