Waveshare General 2inch LCD Display Module IPS Screen 240×320 Resolution with Embedded Controller Communicating via SPI Interface Requires Minimum GPIO for Controlling

Product Information

Image Rotation: Set the rotation Angle of the selected image, preferably after Paint_SelectImage(), you can choose to rotate 0, 90, 180, 270. CPHA determines whether data is collected at the first clock edge or at the second clock edge of the serial synchronous clock; when CPHL = 0, data is collected at the first clock edge. MIRROR_NONE, MIRROR_HORIZONTAL, MIRROR_VERTICAL, MIRROR_ORIGIN correspond to no mirror, horizontal mirror, vertical mirror, and image center mirror respectively.

The vehicle's combat load was 18 smoke shells for M4 tanks with the 75mm or 76mm cannon to 12 shells for M4 assault tanks with the 105mm howitzer. design uses pitch holes in the cover plate that are smaller than the chain pins, requiring the user to press the cover plate onto the pins before installing the spring clip. Aqua-Check standpipes are single or double outlet and can be fitted with a Wras Approved 2" brass 'Double Check Valve' where the application demands, this valve is designed for optimum throughput with virtually no resistance. Note: Because of the size of the internal RAM of STM32 and Arduino, the GUI is directly written to the RAM of the LCD.Raspberry Pi's vc4-kms-v3d will cause fbcp to fail, so we need to close vc4-kms-v3d before installing it in fbcp. You can directly make fill = "WHITE", because the regular color value is already defined Well, of course, you can also use fill = (128,255,128), the parentheses correspond to the values of the three RGB colors so that you can precisely control the color you want.

sudo cmake -DSPI_BUS_CLOCK_DIVISOR=20 -DWAVESHARE_1INCH3_LCD=ON -DBACKLIGHT_CONTROL=ON -DSTATISTICS=0 . The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen. Draw rectangle: In the image buffer, draw a rectangle from (Xstart, Ystart) to (Xend, Yend), you can choose the color, the width of the line, whether to fill the inside of the rectangle. India's Ordnance Factory Board's 51mm E1 mortar is an enhanced version of the two-inch British mortar of World War II; it is still in production and service in India.

c, you can see all the test programs, remove the comments in front of the test programs on the corresponding screen, and recompile and download. Set points of the display position and color in the buffer: here is the core GUI function, processing points display position and color in the buffer. New Image Properties: Create a new image buffer, this property includes the image buffer name, width, height, flip Angle, and color. Supported formulas and equations: Area, circumference, law of sines and cosines, hypotenuse, perimeter, Pythagorean theorem, surface area, and volume.
