How to use bt 10bit mode of DM vpfe
In buffer prior to the completion of the application has the MMAP related operations after executes system calls to the command line, in the command line, mainly completes is DM video vpfe related hardware initialization, Tvp initialization.
Prior to the application layer of the call flow.
To illustrate the API2. And the waiting queue wakeup, precisely in the interruption, also is a frame of data written to buffer.
Then enter the write data to block the way, start waiting queue, until the process is re scheduling. Author similar article X.
I look after both of them Dk6446 character recognition algorithm based on BP neural network Summary C language version Gzzaigcn: Perhaps this is more abstract, but after a good understanding of the source code. More than 3 blog posts for their own reading Linux under the V4L2 video driver under the framework of the source, all for their own summary. In fact, according to the function of the execution process, the function should be preceded by the interrupt function, the function of the stream list to get the current access to the bpfe cache area is understood as buffer.
Embedded geniusopen a new life in the work of the journey; the road is long, meaning the same, seeking static, seeking heart, seeking to enter. This command can be understood as the actual content of the buffer queue operation. Complete code download link http: In this paper, the main content of the above, the video cache queue of the relevant implementation process to carry out an analysis.
