Typedef Documentation

mxc_csi2_frame_handler_cb_t

typedef void(* mxc_csi2_frame_handler_cb_t) (mxc_csi2_req_t *req, int result)

The callback routine used to indicate to indicate transaction has terminated. This is currently unused until multi-frame exposures are implemented.

Parameters

req	The details of the image capture.
result	See Error Codes for the list of error codes.

mxc_csi2_line_handler_cb_t

typedef int(* mxc_csi2_line_handler_cb_t) (uint8_t *data, unsigned int len)
