Hello. In the card I designed, it seems like there is no issue with the communication between the BNO055 sensor and my STM32F103 microcontroller based on the basic "IsDeviceReady" check code I wrote. However, I have attached the signal waveforms I obtained from the logic analyzer program. Is there any problem? What does 0x14 mean? I would greatly appreciate it if you could assist me with this.
Github already has a sensor API for accessing BNO055, and you can access BNO055 based on the API(https://github.com/boschsensortec/BNO055_driver).
I attached example code on STM32 for your reference. Hope it will be helpful for you.
