maintained updated with the last program releases and configurations. So plan to use the
"update" system folder, as explained in the dedicated chapter.
4) Use Shut Down signal to properly close applications at power off
Windows uses an internal digital signal to communicate that the 4GMCU is closing. The
applications will not receive a close message by Windows, but have to poll for the status of
the IPRESHUT signal, and start the closing procedures when this signal is detected to High
level. This is important to disconnect properly from the network and to save.
5) Use Digitax SDK Dlls to simplify the interface with the custom hardware
Our SDK provides not only the platform specifications for compiling the applications with the
EVC, but also gives some DLLs that implement both the basic digital I/O and the serial port
interface, and also the high level protocols for GPS, Card Reader, ComTax2, and AITP
(Automotive Intensive Task Processor) interface. Using this DLL you will have in a little time
the full control of all the hardware included in the MCU and all of its special functionalities.
You will also have sample source codes to see how to use and interface this DLLs.
6) Make bootable SD Card (CE load)
A suggestion is to use the SysUtils application to create a CE Bootable SD Card and then add
to it all the files needed by your application, for example large maps. In this way, you have a
further possibility to load Windows CE if Hard Disk boot files are corrupted.
7) Don't use Windows Registry to save your application settings
We discourage to use Windows Registry for saving application setup, it is suggested to use
setup files instead.
Leave the registry for Windows CE and for System setup, and save the registry only manually
with the SaveReg application.
In this way is not necessary to save the registry from your application, and this contributes to
CE stability because saving a corrupted registry may inhibit CE from starting.
Also a remote setup update is easier and faster to achieve because only a little configuration
file has to be transferred and replaced, not the whole big registry.
