In this demo the general approach on how to communicate with the module and perform high speed measurements with
the ADC are shown.
Communicating with module:
To communicate with the module, a serial comport 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.

Information to convert the RAW ADC data into standard integer values.
