• DATALOG2 and PDetect can also work standalone,
saving all the sensor data at the highest possible rate
onto the SD card.
• DATALOG2 and PDetect can read a custom sensor
configuration from the SD card root folder. To do so, you
can simply save a JSON configuration file in the root
folder of the SD card (same as described in 2.1.1).
• In the same way, you can configure the MLC by saving
the proper UCF in the root folder. Start an acquisition in

loaded from the file itself.
