|
+ Arducam Pivariety series cameras make compatibility layers for various CMOS
|
|
+ sensors and provide a unified command interface. It is programmable through
|
|
+ I2C interface. The I2C address is fixed to 0x0C. Image data is sent through
|
|
+ MIPI CSI-2, which is configured as either 1, 2 or 4 data lanes.
