A read operation is indicated by driving this pin high. The pin defines whether the data lines contain data or the instruction. The voltage at this pin defines the LCD contrast. For most of the LCD modules, you can connect the 5 V line from the Arduino pinout Connect to the GND pin of the Arduino UNO. Let us understand the function of each pin in the 128×64 LCD module. It is a good idea to buy the LCD controller that mentions the LCD controller on board. I encourage you to find the datasheet of the LCD controller IC on the module. You may come across a different board with slightly different pin definitions. The critical difference between the 68 interfaces is the presence of dedicated RD and WR signals in 8080 versus combined RD/WR signals in the 6800 interfaces. The SSD1322 driver supports several modes of communication: Solomon Systech SSD1322 LCD Controller is another example that can support 1128×64 graphical LCD. You can find the datasheet of the LCD controller IC – KS0107 IC here. The above LCD board contains Samsung KS0107 or a similar driver. Built-in controller: Samsung KS 0107/KS 0108 (or equivalent).Display format: 128 x 64 dots (dots and pixels are used interchangeably).Here is the information from the datasheet Here is a link to a graphical LCD board from Vishay. Since this is a monochrome picture, 1 bit of memory is required to store the pixel’s value.Įach pixel can be either 1 or 0. In the case of 128×64, the screen is made up of 128×64 = 8192 pixels. The entire screen is divided into sets of closely placed pixels. This article is part of our series on the different types of displays that you can use with Arduino, so if you’re weighing up the options, then do check out our guide to the best displays to use with Arduino.Ī graphical LCD allows you to bring your graphics on the screen.
