Line Format#

相机的 Line Format 功能使您可以确定 I/O 线路的电气形式。

该功能的使用#

确定 Line Format#

要确定 I/O 线路的电气形式：

设置 LineSelector parameter to the desired I/O line, e.g., Line1.
Get the value of the LineFormat parameter.
此为只读参数。

可能的值#

可能的值包括：

NoConnect: The line is not connected.
OptoCoupled: The line is an opto-coupled I/O line.
OpenDrain, TTL, LVTTL, or RS422: The line is a general purpose I/O (GPIO) line.

示例代码#

C++ (Native)C++ (Generic)C#C (Generic)Python

// 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
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();

/* 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);

# Select the desired I/O line
camera.LineSelector.Value = "Line1"
# Get the electrical format of the line
e = camera.LineFormat.Value
