into Suspend mode (in the case of VV6410/6411/6500). This has a significant improvement on
battery life.
Battery type
This is hardware dependant. The schematics referred to in
1.5V cells.
Quartz crystal
Regardless of the sensor type or anti-flicker requirements, the sensor + STV0680B chipset
operates from a single 12MHz fundamental quartz crystal. For specification requirements, see
Table 13
Numeric LCD interface
STV0680B supports a 2-digit LCD panel only, for alpha-numeric display.
LCD types
STV0680B connects to a non multiplexed, direct drive LCD with 2 x 7 segments. Many LCD types
are compatible with this interface. The LCD refresh frequency is 34.7Hz.
LCD interface pinout
The convention for segment numbering is as follows: ’0’ connects to segment ’a’, ’1’ connects to
segment ’b’, and so on, where a to g are standard for all 7-segment displays, as well as an LCD
common output, giving fifteen signals in total.
Switches and LED’s
The GPIO lines on STV0680B have pre-defined functions as follows, see
interface functionality, and
MODE push button and SHUTTER push button: GPIO0 and GPIO1
Both push button inputs have internal de-bounce circuits, reducing the amount of hardware required
externally. It is recommended that labelling is used on the camera casing to help the user
understand the functioning of the 2-button interface.
Input to select between 50 and 60Hz flicker frequency: GPIO3
This allows for factory setting of the anti-flicker frequency, dependant on the final country of
destination. See also
(see
LED indicator output: GPIO5
The LED output has an 8mA current sinking capability.
Other pins: GPIO2, 4, 6, 7
With STV0680B-001, these pins are un-used and should be tied to GND.
