In this example, the two A/D input ports are directly linked to two different camera
outputs.
The first signal is “MOVE/STOP”, which is LOW when the best focus position has already
been set, and HIGH when a new focus position must be reached.
The other signal is “DIRECTION”: the AOL0223X only takes care of this signal if “MOVE/
STOP” is high.
If DIRECTION is LOW, the output voltage applied to the piezoelectric actuator decreases,
and when DIRECTION is HIGH, the output voltage increases.
A suitable triggering, control and synchronization system is required between
AOL0223X and the camera to implement this kind of control correctly.
2.3.8 Wiring diagrams
This function code is used to write a block of contiguous registers in the controller
register file. The master specifies the starting register address, the number of registers
and the actual data to be written. Registers are addressed starting at zero. The register
data in the request message are packed as two bytes per register. For each register, the
first byte contains the high order bits and the second contains the low order bits. The
normal response returns the function code, starting address, and quantity of registers
written.
Example 1:
AOL0223X is connected to the power supply and to the PC.
The connection to the PC via the ethernet cable is necessary for the electronic control of
the Adaptive Lens.
The default settings for the Ethernet connection are illustrated in Paragraph 11.3.
