Examples: trig 0x1F02 ; manual, timer-based, sense-driven camera (default)

trig 0x0100 ; manual digital capture only

trig 0x0200 ; timer-based capture only

trig 0x0300 ; manual and timer-based capture only

trig 0x1C02 ; sense-driven only (no manual/timer-based photos)

trig 0x0402 ; only run as stationary PIR monitoring camera

tim, dat

Summary: set real-time clock time and date

Syntax: tim <hours> <minutes> <seconds>

dat <day-of-month> <month-of-year> <year>

Description: Set the real-time clock to specific values. Note that the BOOT.BAT

file will need to be modified manually after the tim or dat commands

have been used to prevent the real-time clock from being set to the

same values every time the SenseCam executes the BOOT.BAT file.

Manual time setting is best achieved by using the TIME.CSV file (see

Section 5.5 below).

eewrite

Summary: Specify non-volatile configuration settings

Syntax: eewrite <config-byte> <new-value>

Description: Several non-volatile configuration bytes which control various aspects

of SenseCam operation are stored in the on-chip microcontroller

EEPROM. These may be overwritten using the eewrite command by

specifying the <config-byte> number and the <new-value> to store at

that location. Since this configuration information is stored in non-

volatile memory, having set the desired values, the eewrite commands

in the BOOT.BAT file may be deleted.

Most of the configuration bytes should not be altered by the end user.

Altering their contents may cause problems operating the SenseCam

and in the worst case will render it inoperable. Do not use this

command unless you are confident that you understand what effect it

will have! See 5.7 below for more detail on useful settings.

Examples: eewrite 8 ;

eewrite 9 0x02 ; no power saving

5.5. TIME.CSV system file

The TIME.CSV file in the \SYSTEM directory is used to update the real-time clock on the

SenseCam. On boot up (following a USB disconnect and a power-on) the SenseCam will

use the information in the TIME.CSV file to set the real-time clock, and will then delete the

TIME.CSV file. See Section 3.5 for more details on this process.
