Example 11

Example 12
INT nRet = IS_SUCCESS;

// GPIO1 configured as RX is not supported!
gpioConfiguration.u32Gpio = IO_GPIO_1;

// GPIO2 will be configured as IS_GPIO_COMPORT_RX automatically!
nRet = is_IO(hCam, IS_IO_CMD_GPIOS_SET_CONFIGURATION, (void*)&gpioConfiguration,
sizeof(gpioConfiguration));
// The following code leads to the same setting
// Set configuration of GPIO2 (COM-port RX)
gpioConfiguration.u32Gpio = IO_GPIO_2;
gpioConfiguration.u32Configuration = IS_GPIO_COMPORT_RX;
// GPIO1 will be configured as IS_GPIO_COMPORT_TX automatically!

Example 13
INT nRet = IS_SUCCESS;

// Get the minimum values for the GPIO flash delay and flash duration
nRet = is_IO(m_hCam, IS_IO_CMD_FLASH_GET_GPIO_PARAMS_MIN, (void*)&flashParams,

// Set the minimum values for flash delay and flash duration. Be careful: The normal flash does not work with val
nRet = is_IO(m_hCam, IS_IO_CMD_FLASH_SET_GPIO_PARAMS, (void*)&flashParams,
sizeof(flashParams));
