When we do some image processing, we often involve RGB565 this kind of image data format. Because of its 2 bytes per pixel, the use of RGB565 without pixel transparency can basically guarantee the color of the image and reduce the size of the image data, saving bandwidth. Therefore, RGB565 will be a common format for t

apply to device file/DEV/TTY03.The way the device communicates with the driver depends on the hardware interface. When the data transfer on the device is complete, the hardware sends an interrupt signal through the bus causing the system to execute an interrupt handler. The interrupt handler works in conjunction with the device driver to complete the underlying control of the data transfer.Second, the bare device, also known as the raw partition, is

. The __init__ method initializes part of the data to the corresponding instance property values.6. In particular, the code below uses the pack method of the Python struct library to convert the SRC and DST long values to strings with the specified format parameters, and then uses the Socket.inet_ntoa method to convert a string of numbers of strings to the corresponding IP format. The last assignment to the corresponding SRC or DST variable# readable IP addressself.src_address = socket.inet_ntoa
