Line Format#
Using the Feature#
Determining the Line Format#
To determine the electrical format of an I/O line:
- Set the LineSelector parameter to the desired I/O line, e.g., Line1.
- Get the value of the LineFormat parameter.
This parameter is read-only.
Possible Values#
Possible values are:
- NoConnect: The line is not connected.
- OptoCoupled: The line is an opto-coupled I/O line.
- OpenDrain, TTL, or LVTTL: The line is a general purpose I/O (GPIO) line.
Sample Code#
// Select the desired I/O line camera.LineSelector.SetValue(LineSelector_Line1); // Get the electrical format of the line LineFormatEnums e = camera.LineFormat.GetValue();
INodeMap& nodemap = camera.GetNodeMap(); // Select the desired I/O line CEnumerationPtr(nodemap.GetNode("LineSelector"))->FromString("Line1"); // Get the electrical format of the line String_t e = CEnumerationPtr(nodemap.GetNode("LineFormat"))->ToString();
INodeMap& nodemap = camera.GetNodeMap(); // Select the desired I/O line CEnumParameter(nodemap, "LineSelector").SetValue("Line1"); // Get the electrical format of the line String_t e = CEnumParameter(nodemap, "LineFormat").GetValue();
// Select the desired I/O line camera.Parameters[PLCamera.LineSelector].SetValue(PLCamera.LineSelector.Line1); // Get the electrical format of the line string e = camera.Parameters[PLCamera.LineFormat].GetValue();
// Select the desired I/O line Pylon.DeviceFeatureFromString(hdev, "LineSelector", "Line1"); // Get the electrical format of the line string e = Pylon.DeviceFeatureToString(hdev, "LineFormat");
/* Macro to check for errors */ #define CHECK(errc) if (GENAPI_E_OK != errc) printErrorAndExit(errc) GENAPIC_RESULT errRes = GENAPI_E_OK; /* Return value of pylon methods */ size_t len = 0; char e_str[64] = {0}; /* Select the desired I/O line */ errRes = PylonDeviceFeatureFromString(hdev, "LineSelector", "Line1"); CHECK(errRes); /* Get the electrical format of the line */ len = sizeof(e_str); errRes = PylonDeviceFeatureToString(hdev, "LineFormat", e_str, &len); CHECK(errRes);
You can also use the pylon Viewer to easily set the parameters.
