Description
|
|
|
|
|
***********
|
|
|
|
|
|
|
|
|
|
This sample application uses the Video API to retrieve video frames from the
|
|
|
|
|
video capture device, writes a frame count message to the console, and then
|
|
|
|
|
discards the video frame data.

|
|
|
|
|
On :ref:`mimxrt1064_evk`, The MT9M114 camera module should be plugged in the
|
|
|
|
|
J35 camera connector. A USB cable should be connected from a host to the micro
|
|
|
|
|
USB debug connector (J41) in order to get console output via the freelink
|
|
|
|
|
interface.
