Internal release only on 24/04/2014

  • Add ethernet connection as dhcp server. Now Ethernet and wifi connection have each 4 modes (disable, dhcp client, dhcp server, manual). - Workflow of Network.cpp changed to accommodate the new features. Each time a change is required to either ethernet or wifi, all network services (dhcpcd, dnsmasq, wpa_supplicant) are automatically stopped and re-started. - scan for wifi SSID will take 20s instead of 10s, this is to let enough time to allow stopping and restarting wpa_supplicant - fix github 54, 12, 81

  • format SD card fixed

  • New server running in background from the main application iSTAR. Functionalities: - send info package on request - accept a connection on request and correct identification Nota: the server does not yet have access to the capture parameters

  • github 126: user set Auto HDR, then goes to exposure settings and does not have the choice for manual exposure and vv user set manual exposure and cannot see auto HDR option anymore

  • github 149: - light type added to INF.TXT - auto HDR with fluorescent lights take multiple exposures irrespective to light type, multiple exposures being sufficient to compensate for the band effect - with fluorescent light and single or 3 HDR, exposure time is fixed at values 1/25th, 1/50th, 1/100th and iso automatically optimised.

  • re-introduce the ms information in the frameheader_t as int tv_sec and int tv_usec in istartypes.h that was not present in the github sources.


skipped numbering due to parallel development
