Software update V0.2

Here's the first software update!

Not a huge amount in this one, basically a few features requested by a few scientific users, and a bunch of low-hanging fruit . More major updates will probably have to wait until after the backlog of Kickstarter rewards and store preorders have shipped, since it's so busy leading up to production. Once we hire a software engineer, updates will be much more frequent and significant.

Features added and bugs fixed:

* Added Triggered Exposure and Shutter Gating modes
* Fixed bug where video can be saved to the mount point if no storage device is present
* Fixed minimum exposure time (now 1uS instead of an impossible 10ns)
* Added "About" tab to Util window, showing software version, serial number, and camera info
* Added missing backer Jared Reabow in backers list
* Added support for LUX1310 image sensor silicon revision 2
* Fixed incorrect bitrate computation in save settings window
* Disabled H264 profile and level controls (certain lower levels caused encoder to crash)
* Fixed incorrect shutter slider and exposure text after changing resolution
* Fixed incorrect updating of ROI indicator in Record Settings
* Fixed allowable range of window offset to proper multiples (16, 2). Record settings would not be applied if offset was set other than proper multiple
* Moved close button on keyboard to bottom right
* Changed arrows on keyboard from text eg. "Up" to unicode arrow characters
Known bugs in added features:

* Horizontal line issue is present in Triggered Exposure and Shutter Gating modes, to be fixed
Installation instructions:

* Unzip the Zip file into the root directory of a FAT32 formatted USB stick
* This should result in a camUpdate folder in the root directory of the stick
* Boot up the camera and insert the USB stick
* Backup your calibration data. Tap "Backup calibration data" and wait for this to complete (about 5 seconds). The cal data is now backed up on the USB drive as cal_[serial number].tar
* To install the update, tap Apply Software Update
* A message box should pop up indicating the software update was found. Tap Yes to install the update.
* The screen will go blank for a few seconds, then the updated application will start.
* Done! No need to restart the camera.
What if something goes wrong?
Don't worry, it's impossible to brick the camera. If the update fails for some reason and the camera won't boot, you can reflash the OS SD card yourself to recover the camera. If you need the image file to do this, let us know. It's just like flashing the OS card for a Raspberry Pi. You will need to restore the backed up calibration data after reflashing the card. If you don't have a backup, we have a copy of the original factory cal, available on request.

Next updates in the pipeline:

* Proper trigger delay setting (Timeline/slider, pretrigger percentage, and setting by time rather than frames)
* Remembering settings across reboots
* Indication of dropped frames on save
* Proper boot splash screen

gyppor:
question for you regarding the update and remembering the settings:

I've had issues with white balance, every time I try to set it everything gets a pronounced yellow hue. So far when this has happened I've shut the camera down and re-started to regain the default white balance. I always use the default and it works fine.

Is it possible to reset the settings to default in the firmware version 2.0?

Is it also possible to edit the power-on settings, rather than keep the same settings from one session to the other?
for instance, I'd like to be able to set the encoding to 30fps and the default resolution to 1280x720, but keep everything the same as in version 1.0.

Thanks!

This is great, can't wait to get those dark pixels out of the way.  I know the camera will be amazing with the software development.  Congrats, I'll share this update soon!   

Update went without a hitch. Also kudos on making it update proof by not using a firmware flash but opening software from the card.  Glad to see a device that is ready to go after the update without a reboot. I was put off at first but it's a sweet feature to have.

Electra:
Faultless upgrade. Quick and simple.
Can't wait for persistent settings, everything else I'll enjoy as they come. :)

AimedResearch:
New update trigger issue...  I have a report that the new update will allow a trigger delay only for the on-camera trigger but not the BNC trigger input.  Can anyone verify, I am not with my camera.
