Syntax
INT is_IO(HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
Description
You can toggle the color of the LED on the back of the USB 2 uEye SE camera housing. For the USB 3.1 and USB 3 uEye cameras, you can set the LED flashing.
The nCommand input parameter is used to select the function mode. The pParam input parameter depends on the selected function mode. If you select functions for setting or returning a value, pParam contains a pointer to a variable of the UINT type. The size of the memory area to which pParam refers is specified in the cbSizeOfParam input parameter.
Input parameters
hCam |
Camera handle |
pParam |
Pointer to a function parameter, whose function depends on nCommand. |
cbSizeOfParam |
Size (in bytes) of the memory area to which pParam refers. |
INT nRet = IS_SUCCESS;
UINT nCurrentState = 0;
// Get the current state of the LED
nRet = is_IO(m_hCam, IS_IO_CMD_LED_GET_STATE, (void*)&nCurrentState, sizeof(nCurrentState));
// Set LED to state 1 (red)
nCurrentState = IO_LED_STATE_1;
nRet = is_IO(m_hCam, IS_IO_CMD_LED_SET_STATE, (void*)&nCurrentState, sizeof(nCurrentState));
// Toggle LED state to green
nRet = is_IO(m_hCam, IS_IO_CMD_LED_TOGGLE_STATE, NULL, 0);
