The Goal For a small project I used the ATmega328P MCU – and then the small project somewhat exploded and I needed more and more I/O-Pins. Suddenly all but the PB6 and PB7 pins were in use, and I needed exactly two more… The Arduino IDE did not offer pin numbers for these pins, since they are used for the crystal oscillator on Arduino. My project however did not rely on ultra precise timing, so the internal oscillator was more than enough, leaving the two pins open for other use, but how to address them? I guess with Atmel Studio this […]
The BNO055 is a capable IMU that has on-chip sensor fusion and filtering. Interfacing can be done using I²C and UART. When used with the Raspberry via I²C, you get erroneous measurements because of the I²C clock stretching bug of the Raspberry. Using the UART, results are correct.
