camtrig - firmware for precisely timed trigger generation with synchronized analog input
Triggering your camera is useful to synchronize it with other devices. These other devices can be other cameras, so that images are taken simultaneously, or a computer, so that the images can be correlated with other activity.
Camtrig is firmware for the $30 AT90USBKEY USB development board that:
The device is accessed using the Python motmot.fview_ext_trig package.
Camtrig is built with GCC-AVR using the LUFA library for the AT90USBKEY. To load the firmware onto the device, use dfu-programmer or FLIP to transfer the hex file camtrig.hex to the device in Device Firmware Upload (DFU) mode.
The source code for the camera trigger device is kept in the fview_ext_trig git repository under the CamTrigUSB directory. Alternatively, download the released Python code at the PyPI page and the firmware, camtrig.hex, from github.
