Q2: why does igrr's code set each DMA descriptor's EOF to 1? Q3: If no circular link-list is used but a set of descriptors whose size is the number of camera lines - is only the last descriptor's EOF one? The tech document on I2S camera processing states that data is passed whe...
* This function detects and configures camera over I2C interface, * allocates framebuffer and DMA buffers, * initializes parallel I2S input, and sets up DMA descriptors. * * Currently this function can only be called once and there is * no way to de-initialize this module. * * @param c...
On a whim, I just tried re-flashing it from a different PC, which probably has older versions of all the drivers and it's given me a different error: Code:Select all [E][camera.c:1113]camera_probe(): Detected camera not supported. [E][camera.c:1379]esp_camera_init(): Camera prob...

当使用1帧缓冲区时,驱动程序将等待当前帧完成(VSYNC)并启动I2S DMA。 获取帧后,I2S将停止,帧缓冲区返回到应用程序。 这种方法可以更好地控制系统,但会导致获得帧的时间更长。 当使用2个或更多帧缓冲时,I2S以连续模式运行,每个帧被推送到应用程序可以访问的队列。 这种方法会给CPU/Memory带来更大的压力,但允许...
