ISC Root Device

Detailed Description

Manages NvMediaISCRootDevice objects that are the root of the Nvmedia ISC object system.

The NvMediaISCRootDevice object manages an I2C port on the host hardware device.

Function Documentation

NvMediaISCRootDevice* NvMediaISCRootDeviceCreate

(

uint32_t

portCfg

)

Creates an NvMediaISCRootDevice object.

Parameters

[in]

portCfg

The CSI/I2C ports that this root device. Using macro ISC_RDEV_CFG(csi, i2c) to generate this value is strongly recommended. In the case when the application is being run on a slave Tegra while master Tegra is in charge of controlling isc devices, using macro 'ISC_SLV_RDEV_CFG(csi, i2c)' is strongly recommended. The following I2C ports are supported: NVMEDIA_ISC_I2C_BUS_0 NVMEDIA_ISC_I2C_BUS_1 NVMEDIA_ISC_I2C_BUS_2 NVMEDIA_ISC_I2C_BUS_3 NVMEDIA_ISC_I2C_BUS_4 NVMEDIA_ISC_I2C_BUS_5 NVMEDIA_ISC_I2C_BUS_6 NVMEDIA_ISC_I2C_BUS_7 NVMEDIA_ISC_I2C_BUS_8 NVMEDIA_ISC_I2C_BUS_9 NVMEDIA_ISC_I2C_BUS_10 NVMEDIA_ISC_I2C_BUS_11 NVMEDIA_ISC_I2C_SIMULATOR The following CSI ports are supported: NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_A NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_B NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_AB NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_CD NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_E NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_C NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_D NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_F NVMEDIA_IMAGE_CAPTURE_CSI_INTERFACE_TYPE_CSI_EF

Returns

device The new device's handle or NULL if unsuccessful.

void NvMediaISCRootDeviceDestroy

(

NvMediaISCRootDevice *

device

)

Destroys an NvMediaISCRootDevice object.

Parameters

[in]

device

Handle of the device to destroy.

Returns

void
