Machine Vision Camera SDK (C) Developer Guide
Remarks
After the device is connected, call this API to set specified int nodes. For value of strKey, see
"MvCameraNode.xlsx" sheet. The node values of IInteger can be set through this API, strKey value
corresponds to the Name column.
Example
The following sample code is for reference only.
#include "MvCameraControl.h"
void main()
{
int nRet = -1;
void* m_handle = NULL;
//Enumerate all devices corresponding to specified transport protocol
within subnet
unsigned int nTLayerType = MV_GIGE_DEVICE | MV_USB_DEVICE;
MV_CC_DEVICE_INFO_LIST m_stDevList = {0};
int nRet = MV_CC_EnumDevices(nTLayerType, &m_stDevList);
if (MV_OK != nRet)
{
printf("error: EnumDevices fail [%x]\n", nRet);
return;
}
int i = 0;
if (m_stDevList.nDeviceNum == 0)
{
printf("no camera found!\n");
return;
}
//Select the first found online device and create device handle
int nDeviceIndex = 0;
MV_CC_DEVICE_INFO m_stDevInfo = {0};
memcpy(&m_stDevInfo, m_stDevList.pDeviceInfo[nDeviceIndex],
sizeof(MV_CC_DEVICE_INFO));
nRet = MV_CC_CreateHandle(&m_handle, &m_stDevInfo);
if (MV_OK != nRet)
{
printf("error: CreateHandle fail [%x]\n", nRet);
return;
}
//Connect device
unsigned int nAccessMode = MV_ACCESS_Exclusive;
unsigned short nSwitchoverKey = 0;
