6. APC220
In combination with the APC220 module, ASURO can be controlled
via the „ASURO control“ programme that needs to be installed on
the PC. “ASURO Control” can be downloaded from the website. The
software has been written in Visual Basic and is available to the user
as a variable source.
The ASURO software needs to be slightly adjusted. This software is
also an open source product.
The adjustment is necessary because the system has to transfer a
protocole that includes a control byte and a set of information bits.
Fig. 12 shows how the application (in orange) transmits the signal
for the data request at the PC. The ASURO system replies with the
reply data in red.
Protocole from ASURO to PC:
Fig. 12 : Communications exaomple
The ASURO software contains some functions to send requests to
the sensors and to control the motors. If the control programme
sends a request, ASURO transmits immediately the data to the
client. At this stage you have the option to add 4 more information
bytes to the signal. This could e.g. be a thermometer that is
connected to the free connectors of the extension set.
The following text describes the code for the data transfer of this
kind of measurement data.
