How to use extra 9K flash memory in LSM5DSO for storing accelerometer and gyroscope data
Hi,
I am using LSM6DSOx for a wearable device project. Currently all the accelerometer data is written in FIFO and device wait for data ready interrupt. This helps system to maintain low power mode and operate only when FIFO data is ready.
Currently FIFO is using only 3K of memory. But I want to use the additional 9K flash memory so that I can increase system sleep period.
Below is the accelerometer configurations that I am using. Please guide me what changes needs to be done to use 9K flash memory
