| - | Note, full frame-grabs are only supported through the USB interface and [[wiki:v2:building_the_libpixyusb_example_on_linux|libpixyusb]], not through the SPI, I2C or UART serial interfaces (i.e. Arduino). [[wiki:v2:building_the_libpixyusb_example_on_linux|Libpixyusb]] includes a frame-grab example called [[https://github.com/charmedlabs/pixy2/tree/master/src/host/libpixyusb2_examples/get_raw_frame|get_raw_frame]]. It uses a special function called getRawFrame() that isn't part of the video API. :( We could add this, but where would a 65K-byte raw frame fit in Arduino memory? | + | Note, full frame-grabs are only supported through the USB interface and [[wiki:v2:building_the_libpixyusb_example_on_linux|libpixyusb]], not through the SPI, I2C or UART serial interfaces (i.e. Arduino).
