I would like to know miminum I2C communication interval between transmissions.
I mean, BNO055 supports clock stretching. So then, required time of one transmission may
How could I determine the minimum transmission interval?
Thank you and best regards.
Solved! Go to Solution.
All I2C required timing are already included in the BNO055 datasheet.
As additional information, you can put around 2 - 3 us interval between I2C command under normal power mode.
For reading sensor data, just polling as defined ODR should be OK or you can use interrupt based reading.
Sorry for late to reply.
Thank you very much for your advice.
As far as I know, the processor from Broadcom that is used on the Raspberry Pi has a bug in the I2C master and doesn't support clock stretching as per the standard specification. It is only within spec for speeds of 3.4MHz which the BNO055 doesn't support.
