Hello together,
i bought a Digil Pmod CMPS2 3axis compass modul to get the compass data on my arduino mega 2560. To start i followed all the steps described on your websites. After programming a long time and using all kind of available code examples for this sensor, the result in the serial monitor is the same: Pmod measures 141.11 degrees all the timeĀ“. There is no chance to get functional data of this sensor.
Like i said, i use Arduino Mega 2560, combining the SCL(21), SDA(20), VCC(3.3V) and GND pins.
