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

Draw line: In the image buffer, draw line from (Xstart, Ystart) to (Xend, Yend), you can choose the color, the width and the style of the line. Select image buffer: the purpose of the selection is that you can create multiple image attributes, image buffers can exist multiple, and you can select each image you create. Compared with other fbcp projects, this project uses partial refresh and DMA to achieve a speed of up to 60fps.

If you use the bookworm system, you can only use lgpio library, bcm2835 and wiringPi can't be installed and used.We provide complete supporting Raspberry Pi demos (BCM2835 library, WiringPi library, and Python demos), STM32 demos, and Arduino demos.

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. 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. Select image buffer: The purpose of the selection is that you can create multiple image attributes, there can be multiple images buffer, you can select each image you create. The first parameter is a tuple of 2 elements, with (40, 50) as the left vertex, the font is Font2, and the fill is the font color.

Supported formulas and equations: Area, circumference, law of sines and cosines, hypotenuse, perimeter, Pythagorean theorem, surface area, and volume. Note: Each character library contains different characters; If some characters cannot be displayed, it is recommended that you can refer to the encoding set ro used. Dot_Style: the size of a point that expands from the center of the point or from the bottom left corner of the point to the right and up.

interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. 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 use the upper application to do, and we provide some basic functions here about some graphics processing in the directory GUI_Paint. We have carried out the low-level encapsulation, if you need to know the internal implementation can go to the corresponding directory to check, for the reason the hardware platform and the internal implementation are different. Please make sure the SPI is not occupied by other devices, you can check in the middle of /boot/config.
