-------------------------------------------------------------------------------
- ChangeLog O-3000 Host Driver
-------------------------------------------------------------------------------
Version 2.0.2
2018-04-11-PR
* Function handle_transfer() rewritten:
The image frame synchronization was a bit hacky. Image frames were passed only to the
overlaying application after the next image frame has been received. But when receiving a single
snapshot, there won't follow an image. This causes a delay of one image until the application
receives it. Now the function passes images to the application after a image is
received completely without checking the preamble of the following image.
* Bug race condition at o3000_init() function:
Accessing the session table for getting next free session and allocation session structure
must be atomic.
* New function o3000_get_num_cam() added:
This function returns the number of connected O-3000 cameras to the system.
* New loglevel O3000_LOG_VERBOSE added:
This loglevel will set the libusb to debugging mode and is very useful for debugging purposes.
Version 2.0.1
2015-08-11 -PR
* Bugfix in function handle_transfer(): A negative byte offset was calculated when the resolution
has changed during wrap-around. A SEGFAULT occured.
* Fields added to image header and image header version update to 4:
- data rate in bytes/seconds
- frames per seconds
- field-of-view added used by lense distortion algorithm
* Short USB bulk transfers are supported now by the driver. Therefore the resolution
doesn't have to be a multiple of 512 bytes anymore and binning is done correctly.
There are following restrictions about image resolution settings:
- Window size must start with an even pixel coordinate (see examples below)
- Minimum image resolution is 640x480.
- Binning is allowed at full-screen only (1280x960)
E. g. valid window: X = 110 to 1111, Y = 32 to 917
E. g. invalid window: X = 111 to 1111, Y = 33 to 917 --> coordinate 111 and 33 are odd numbers
2016-03-01
* Calling convention added for Win32 and Win64.
Version 2.0.0 - 2015-02-16
* PR: Multi camera sessions capability. The host can scan the number of cameras and establish a connection to
each of them. Sending a XML message to the camera uses the synchronous API with OS dependet timeout handling.
Version 1.0.0 - 2015-02-16
* PB: Inititial version
