luciasar00 Posted March 1, 2016 Report Share Posted March 1, 2016 Hello, We're testing a new design that uses multiple MPU6050s connected to a TCA9548a I2C Splitter, mediated by an Arduino. We'd like to be able to sample the IMUs for DMP data individually based on instructions sent to the Arduino, but we're not sure how to request the FIFO buffer for data that isn't streaming. We don't need the system to be lossless - whatever data comes in between requests is irrelevant. We tried having the system sample all the IMUs every cycle and store that data until requested, but because of how many sensors we're the I2C transactions slowed the whole system down to unacceptable levels. There's some part of the FIFO buffer that's only for the most recent data, correct? Is there some way we can access that and ignore the rest? lapedNok 1 Quote Link to comment Share on other sites More sharing options...
DuckDam Posted July 4, 2016 Report Share Posted July 4, 2016 Good day, I have the same problem that you have. Please let me know if you got this to work. I need 3xMPU6050s connected to a TCA9548A via a Mega2560 Regards Quote Link to comment Share on other sites More sharing options...
