The next step is to provide 5V to the LCD.
For this we connect the '5V' on the :KnSgtg:Arduino:: to the breadboard. We start by supplying the breadboard with 5V on the + rail (red) and GND on the - rail (blue).
ST7920 pin overlay The circuit Step 1 - breadboard If the pin overlay does not not fit exactly, check your printer settings to see if the magnification is set to 100%. You can now place this exactly at the bottom of your display and see the pin labels again. To solve this I've created a pin overlay. If you put the display into the breadboard you'll see that the pin labels are no longer visible. Printing the ST7920 pin overlayīreadboard. The big advantage is that you don't have to find out how to control each individual display. Currently U8g2 supports over 200 different displays. Text is also no problem.Īn overview of all available functions can be found on the U8g2 reference page. U8g2 allows you to draw graphic elements such as lines, rectangles, circles on the screen. The U8g2 library is specially made to easily control monochrome displays in an universal way. More technical information is described in the ST7920 datasheet U8g2 library ST7920 refers to the display controller which is made by Taiwanese Sitronix. The light is transmitted differently making it appear black. With LCD it looks like the boxes can become black. These segments are placed as an '8' in some screens like a digital clock, in others as pixels. This screen is made up of segments that can be turned on or off.
ST7920 is a so-called LCD which stands for Liquid Crystal Display.
