Galvanized Roof Steel Small Oled Screen - 240160-cog-13 LCD with character library RA8806 LCD module – Huijing

RA8806 is a dot matrix liquid crystal display (STN-LCD) controller with text and drawing mode. It has built-in dual page display memory and 512Kbyte ROM font code, which can display full type (16×16 pixels). Traditional Chinese characters (BIG5, 13973 fonts) or simplified Chinese characters (GB, 9216 fonts). In the same series, the RA8806-J has built in 6355 fonts for the Japanese JIS standard Chinese character first and second horizontal Japanese character fonts. The RA8806 also has 4×256 built-in half-word (8×16 pixels) letters and symbols for English and European countries, which is in accordance with ISO8859-1~4 (or Latin-1~4). ASCII code.
The RA8806 supports the MPU interface of the 8080/6800 series that can be converted to a 4-bit or 8-bit data bus. For the LCD driver interface, the RA8806 can also be configured as a 4-bit or 8-bit data bus. In normal mode, the RA8806 can support LCD panels up to 320×240 dots resolution, while in extended mode, it can support 640×240 or 320×480 dot resolution LCD panels, while using text rotation to achieve vertical text. display effect. The RA8806 also has a built-in smart touch scan controller that supports a 4-wire resistive touch scan interface, while a programmable pulse width modulator (PWM) can be used to adjust the contrast or backlight of the LCD panel. . The RA8806 also offers a powerful and intelligent 4×8 (32-key) or 8×8 (64-key) keyboard scan interface, which includes long button functions, while allowing users to easily navigate through appropriate interrupt and polling mechanisms. The functions of touch scanning, keyboard scanning, and power management are operated, so that the burden of the MPU can be effectively alleviated. Built-in 512Byte font creation memory (Character Generation RAM, CGRAM) allows users to create up to 16 full or 32 half-type fonts or symbols, even when only one display layer is used, the other does not The used layer memory can also be used as a font to create memory. In this setting state, there are enough words or symbols (300 full or 600 half-words) that can be created by the user.
In addition, the RA8806 provides a display of 4 grayscale patterns in grayscale mode, where the data arrangement is compatible with most grayscale patterns and is quite easy to write. The RA8806 also provides quite a few useful features, such as area scrolling, text highlighting, bold text, text magnification, memory clearing, and more. The RA8806 also offers an innovative feature – no-flicker (no-flicker), which effectively removes snowflakes that are generated by frequent memory reads and writes. This mode is provided by the RA8806. The quality of the LCD display can be easily improved.
The RA8806 is a powerful and easy-to-use LCD display controller that provides a complete solution for mid-size LCD display control, allowing users to save considerable time and cost on system hardware and software development.
