The modes of operation are described in
It may also be desirable to include an on-off slider switch. This has advantages and disadvantages,
and its exact function is discussed further in the reference design available from ST.
Where a flashgun module is included in the camera, it will be necessary to include a flash on/flash
off push button or slider switch, dependant on the exact flashgun module design. possible
implementations are discussed in a separate application note AN1312 regarding flashgun
implementation, available from ST.
LED indicator
An LED display camera status, i.e. to show that the camera is not in Standby/PC suspend mode.
Picture counter using 2 x 7 segment display
STV0680B stores a picture counter value, which shows how many images can still be captured.
STV0680B supports a 2x7 segment LCD panel. In ‘Snapshot’ mode and continuous capture mode,
this LCD panel displays the number of pictures still available, which is useful to identify when the
user is approaching the maximum number of images which can be stored (see
possible to clear the images stored in memory, in order to continue taking pictures. In other modes,
this LCD panel shows displays a 2-character code, which helps the user to navigate around the
modes.
A CIF camera with STV0680B and 64Mbit SDRAM can store up to 320 images by using QCIF
mode. Where >99 images are still available, the LCD display will remain at 99. Where (no. of
images available) <99, the LCD display will show the number of images available, as is the case
with all other modes.
For suitable numeric LCD panel types, see
Piezo buzzer
An on-chip Pulse Width Modulator (PWM) on STV0680B is used to generate buzzer sounds to
signal certain events. The following are typical of the type of events which are indicated by the
buzzer, and each has its own distinctive sound:
1 Mode button (Wake-up/Switch between modes): This button allows the user (1.1) to wake the
