Subject: [PATCH 11/13] iio: imu: inv_mpu6050: dynamic sampling rate change
Date: Wed, 12 Feb 2020 18:40:46 +0100 [thread overview]
Message-ID: <20200212174048.1034-12-jmaneyrol@invensense.com> (raw)
In-Reply-To: <20200212174048.1034-1-jmaneyrol@invensense.com>
Sampling rate can be changed while the chip is running. It can
be useful thus do not prevent it.
