10. How to add plug-in's for new image sensors
|
||||
==============================================
|
||||
It should be easy to write plug-in's for new sensors by using the small API
|
||||
that has been created for this purpose, which is present in "sn9c102_sensor.h"
|
||||
(documentation is included there). As an example, have a look at the code in
|
||||
"sn9c102_pas106b.c", which uses the mentioned interface.
|
||||
|
||||
At the moment, possible unsupported image sensors are: CIS-VF10 (VGA),
|
||||
OV7620 (VGA), OV7630 (VGA).
