Calling External Code in LabVIEW PDA for Pocket PC - Battery Information Example
Print
Note: For LabVIEW PDA 8.0 and later see the shipping examples for the latest example.
This example is intended to illustrate how to call external code using the LabVIEW PDA for Pocket PC module. This example in particular shows how to call to the Pocket PC OS and retrieve information regarding the battery of the device. The same procedure would be used for other calls to external code. A stub dll must be created in order for LabVIEW to be able correctly us the Call Library Function Node. This stub dll only has to have to proper function declaration as the code actually used when built for the Pocket PC device is taken from the .c or .lib file attached in the Build PDA Application dialog box. The stub dll is built as a normal Windows dll. The PPCBatt.dll must also be copied to the Windows directory on the device. The Visual Studio 6.0 project for the stub dll and the Embedded Visual C++ project for the Pocket PC dll is included. Embedded Visual C++ should already be installed if the LabVIEW PDA for Pocket PC module is installed.
Note: LabVIEW PDA 7.0 uses Embedded Visual Tools 3.0, while LabVIEW PDA 7.1 uses Embedded Visual C++ 4.0. That attached examples include projects for their respective versions.
