I've verified functionality (CTRL_REQ1 = 0x03) and had data communicating with a micro-controller. After a while acquisitions stop. I have verified that the active bit is still enabled and i2c communication is still working (WHO_AM_I still returns 0xD7). I've even tried doing a software reset and reenabling the chip, but nothing changes. It just resends the last data acquisition. Any ideas on how to get it acquiring again?
