• LPS Arduino library

  This is a library for the Arduino that interfaces with our LPS22DF, LPS25HB, LPS25H, and LPS331AP pressure/altitude sensor carriers as well as the pressure sensors on the various AltIMU-10 modules, which can be found here. It makes it simple to read the raw pressure data from the sensor, and it provides functions to help calculate altitude based on the measured pressure.

• MinIMU-9 + Arduino AHRS

  This Arduino program (sketch) allows an Arduino-compatible board like an A-Star connected to a MinIMU-9 v6 or AltIMU-10 v6 (or older versions of those boards) to function as an attitude and heading reference system, calculating estimated roll, pitch, and yaw angles from sensor readings that can be visualized with a 3D test program on a PC. It is based on the work of Jordi Munoz, William Premerlani, Jose Julio, and Doug Weibel.
