must be connected to an USB connector of
the computer.
Camera control is performed by Microchip
MCP23S08 device
, which is an
input/output port managed by SPI. A library is provided to make easier for user to
develop programs with the camera module. The basic functions are the camera ON and
OFF, and the selection of the transmission channel from de camera to the video
Moway
Videocap
. User have to select the same channel (from 1 to 4) both in program and
Moway Videocap
. The status of the camera is shown by a LED on camera board.
As interface, the device has four pins available for the SPI bus, two more pins for
controlling the module and another two for the supply.
NOTE: Both camera transmission and RF module transmission are in the same
frequency band. So that, when camera is active, RF module reception distance
decreases.
