2.9 Inch 12864B V2.0 Blue Glcd Module
Spi 5V 128x64 Pixel Graphic Lcd Display Screen Electronic Circuit Indicator Menu Image Text COG LCM
In some batches, a version of the lcd without a pot on the back may arrive. On this type of product you can adjust the contrast in 2 different ways. You can adjust the brightness by connecting an external pot to the lcd over the relevant pin. Or you can also control the contrast in software. The code snippet you will use for this is as follows.
U8G2_ST7920_128X64_F_SW_SPI u8g2(U8G2_R0, /* clock=/ 18, / data=/ 23, / CS=/ U8X8_PIN_NONE, / reset=*/ U8X8_PIN_NONE);
12864b blue graphic lcd module. It is an lcd screen with 2.9 inch 128 column 64 row resolution. It has an ST7920 driver IC. The product can be operated over the parallel port. In addition, it can also be driven with serial communication using very few pins over the Spi port. It stands out with being easily usable from the spi port by many systems such as Arduino.
Unlike character lcds, text and graphics can be created in the desired sizes. It gives the possibility of creating very nice images, menus and texts by making 8192 dots active or passive in the desired way.
It is white in color on a blue base. With its small structure it takes up little space in circuits. It can operate in a wide temperature range. It has low power consumption. It can operate with a DC 5V supply.
