Communicating with module
To communicate with the module, a serial COM-port with a speed set to 115200 bits needs to be opened. Commands consists of a single character in UTF-8 encoding. It is good practice to communication with the module following these steps:
...
These steps apply also for read operations.
Using the ADC for high speed consecutive measurements
The module provides a method to gather highly accurate consecutive ADC measurements in a single event. In this mode of operation, one mega sample of ADC values are performed and stored inside the modules SD-RAM.
...
Convert the RAW ADC data into standard integer values.
