Functions
peak_status	peak_FirmwareUpdate_CompatibleCameraList_Get (const char gufFileName, peak_camera_descriptor cameraList, size_t *cameraCount)
	Get a list of cameras that can be updated using the provided .guf-File.

peak_status	peak_FirmwareUpdate_Execute (peak_camera_id cameraID, const char *gufFileName)
	Upload the firmware provided by the guf file to the given camera.

Detailed Description

Functions in this module can be used to work with and upload firmware files to a camera. The firmware is distributed separately in form of .guf (Generic Update Format) files.

As an alternative to integrating firmware update procedures into your own application you can also use the installed firmware update tool, which is provided by the setup. On most systems this can be achieved by double clicking the .guf file.

Note: The firmware update features are only available for cameras with the interface technologies peak_interface_technology_U3V and peak_interface_technology_GEV.

The following sample code shows how to determine what cameras are compatible with a given guf file, and how to update them.

Note: Error handling is omitted for the sake of brevity.

// NOTE: We need to update the camera list, as it is used by
//       `peak_FirmwareUpdate_CompatibleCameraList_Get`
peak_CameraList_Update(NULL);
 
const char* gufPath = "GV-589x-C_3.30.21242.guf";
size_t size = 0;
peak_FirmwareUpdate_CompatibleCameraList_Get(gufPath, NULL, &size);
printf("Found %zu cameras that can be updated using the GUF file at: %s\n", size, gufPath);
 
peak_camera_descriptor* compatibleCameras = malloc(size * sizeof(peak_camera_descriptor));
peak_FirmwareUpdate_CompatibleCameraList_Get(gufPath, compatibleCameras, &size);
 
for (int i = 0; i < size; ++i)
{
    const peak_camera_descriptor* compatibleCamera = &compatibleCameras[i];
    printf("Updating camera: Model %s Serial %s\n", compatibleCamera->modelName, compatibleCamera->serialNumber);
    peak_FirmwareUpdate_Execute(compatibleCamera->cameraID, gufPath);
}
 
free(compatibleCameras);

For a practical example that includes message and error handling, refer to the provided firmware_update_c sample.

Enumeration Type Documentation

◆ peak_firmware_update_status

enum peak_firmware_update_status

Status of a firmware update step.

Enumerator
PEAK_FIRMWARE_UPDATE_STATUS_STARTED	The update (step) has been started.
PEAK_FIRMWARE_UPDATE_STATUS_PROGRESS	The update step has made progress.
PEAK_FIRMWARE_UPDATE_STATUS_FINSIHED	The update (step) has successfully finished.
PEAK_FIRMWARE_UPDATE_STATUS_FAILED	The update (step) has failed.

◆ peak_firmware_update_step

enum peak_firmware_update_step

Steps of the firmware update procedure.

Enumerator
PEAK_FIRMWARE_UPDATE_STEP_TOTAL	Step representing the whole update process.
PEAK_FIRMWARE_UPDATE_STEP_CHECKPRECONDITIONS	The firmware update is checking for compatability with the camera.
PEAK_FIRMWARE_UPDATE_STEP_ACQUIREUPDATEDATA	The firmware update is loading the firmware files to be uploaded.
PEAK_FIRMWARE_UPDATE_STEP_WRITEFEATURE	The firmware update is modifying camera properties.
PEAK_FIRMWARE_UPDATE_STEP_EXECUTEFEATURE	The firmware update is running tasks on the camera.
PEAK_FIRMWARE_UPDATE_STEP_ASSERTFEATURE	The firmware update is validating the cameras state.
PEAK_FIRMWARE_UPDATE_STEP_UPLOADFILE	The firmware file is uploaded to the camera.
PEAK_FIRMWARE_UPDATE_STEP_RESETDEVICE	The firmware update resets the device and waits for it to reconnect.

Function Documentation

◆ peak_FirmwareUpdate_CompatibleCameraList_Get()

peak_status peak_FirmwareUpdate_CompatibleCameraList_Get	(	const char *	gufFileName,
		peak_camera_descriptor *	cameraList,
		size_t *	cameraCount
	)

Get a list of cameras that can be updated using the provided .guf-File.

This function implements the Two Staged Data Query principle.

Parameters

[in]	gufFileName	Path to a .guf file
[out]	cameraList	Pointer to a list of camera descriptors. If `cameraList` is NULL, `cameraCount` will contain the number of cameras that are compatible with the .guf file at `guf`.
[in,out]	cameraCount	If `cameraList` is NULL: `cameraCount` will contain the number of items that `cameraList` needs to be able to hold. If `cameraList` is not NULL: in: Number of items that `cameraList` is able to hold. out: Number of items that were written into `cameraList`.

Note: Relies on the camera list being up to date. See peak_CameraList_Update.

Attention: Only cameras that are closed and can be opened will be listed. Make sure network cameras have their IP configured correctly.

Returns: PEAK_STATUS_SUCCESS Operation was successful; no error occurred.; PEAK_STATUS_INVALID_PARAMETER Either guf is not a valid path, or cameraCount is a nullptr.; PEAK_STATUS_BUFFER_TOO_SMALL cameraList is not able to hold the required amount of items.; PEAK_STATUS_NOT_INITIALIZED The library is not initialized.; PEAK_STATUS_ERROR An unexpected internal error occurred.

◆ peak_FirmwareUpdate_Execute()

peak_status peak_FirmwareUpdate_Execute	(	peak_camera_id	cameraID,
		const char *	gufFileName
	)

Upload the firmware provided by the guf file to the given camera.

This function is blocking. If you want to be informed about the progress, see the PEAK_MESSAGE_TYPE_FIRMWARE_UPDATE message.

The camera must not be opened in order to upload a firmware.

Note: During a firmware upload, the camera will be restarted, therefore the camera needs to be re-discovered using peak_CameraList_Update after the upload is done.
