The iX example project
The cyclic check for USB and SD media is done inside the script module SCM_USB_SD_Check.
4.1 The Script Module
Inside the script module the following Namespace is inserted additionally to
enable access to the file system.
using System.IO;
Every iX script module brings a “Created” method with it, which is perfect to
initialize stuff as it is worked on exactly once at the start of the iX
project.
// The method is invoked when the script module object is created.
void SCM_USB_SD_Check_Created(System.Object sender, System.EventArgs e)
{
m_Timer= new Timer();
m_Timer.Enabled = true;
m_Timer.Interval = 1000;
//ms – adjust time for cyclic check here.
m_Timer.Tick += OnTimerTick;
}
// The method is invoked when the script module object is created.
void SCM_USB_SD_Check_Created(System.Object sender, System.EventArgs e)
{
m_Timer= new Timer();
m_Timer.Enabled = true;
m_Timer.Interval = 1000;
//ms – adjust time for cyclic check here.
m_Timer.Tick += OnTimerTick;
}
// Cycle
private void OnTimerTick(System.Object sender, System.EventArgs e)
{
if(Directory.Exists(“\\Hard Disk”))
// Check if USB key is connected
Globals.Tags.USB_plugged_In.SetTag();
// Set tag if connected
else
Globals.Tags.USB_plugged_In.ResetTag();
// Reset tag if disconnected
if(Directory.Exists(“\\Storage Card”))
// Check if USB key is connected
Globals.Tags.SD_plugged_In.SetTag();
// Set tag if connected
else
Globals.Tags.SD_plugged_In.ResetTag();
// Reset tag if disconnected
}
Adding the USB SD media Detection
Implementation
-
Import the script module “SCM_USB_SD_Check” , see example project (iX_Detect_USB_SD_V1_0_0).
-
Create the Tags “USB_plugged_in” and “SD_plugged_in” with Datatyp BOOL.
-
Optionally import Screen1 of the example project (iX_Detect_USB_SD_V1_0_0).
-
Adapt the screen to your needs.
-
Transfer the application.
-
Run the application.
5.1 Import the project parts
Follow the steps to add the enclosed screen and the script module to your iX project:
- Unpack the enclosed example ZIP-file to a temporary folder.
- Start iX Developer and load your project.
- In the Project Explorer, right-click in the lower left corner (1. in the picture)
- In the list, select Import… (2. in the picture)
- Navigate to the temporary folder, where you unpacked the ZIP-file and select SCM_USB_SD_Check.neo, click [Open].
- Select Screen1.neoxaml, click [Open].
- Done!
