Main communication commands

This section shows the basic sequence of commands to start a data communication session

and to retrieve the acceleration data from Evaluation kit:

The first step is to connect the board and to bring the microcontroller out from 3-state mode:

ek S ek A ek 0 ek 0 (ASCII) --> 65 68 53 65 68 41 65 68 30 65 68 30 (Hex)

with these two command user can start the single data acquire session:

ek O ek o ek u ek a (ASCII) --> 65 68 4F 65 68 6F 65 68 75 65 68 61 (Hex)

or continue data acquisition:

ek O ek o ek n ek n (ASCII) --> 65 68 4F 65 68 6F 65 68 6E 65 68 6E (Hex)

the command to stop the acquire session is:

ek O ek o ek f ek f (ASCII) --> 65 68 4F 65 68 6F 65 68 66 65 68 66 (Hex)

In the same way the user can retrieve informations from the Evaluation Kit such as the

version of the Firmware loaded onto the microcontroller.

Note:

The commands supported by the Evaluation Kit are intended for the usage with a dedicated

SW written by the user and running on PC. The method described above involving the

usage of the hyper terminal is only intended to help the user to understand how to handle

the communication with the board and not to acquire, to set and to manipulate data.
