The full user manual for software V0.2 is now out, go find it at the resources page

As always, comments/suggestions are appreciated.


Software Dev / Software update V0.2
« on: July 12, 2017, 09:40:53 PM »
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

Here's a draft of the Chronos 1.4 user manual. There are some sections that are not written yet, but it would be great to get some of you to review it. Any comments or suggestions are greatly appreciated.

If anyone wants to help writing any of the missing sections, that would also be great, and would get the full manual out faster.

Chronos User Discussion / List of good (and bad) SD cards
« on: July 01, 2017, 12:54:34 PM »
Let's make a list of known working and not working SD cards for Chronos, since some people seem to be having problems with video skipping on certain cards.

I have had very good luck with The following cards:

Lexar Professional 633x UHS-I

SanDisk Ultra 32GB microSDHC UHS-I (SDSQUNC-032G-GN6MA) (These were included with the promo cameras sent out before the Kickstarter)
