TFT 16-bit Display Library

TFT 16-bit Library

Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film transistor (TFT) technology to improve image quality (e.g., addressability, contrast).
TFT LCD is one type of active matrix LCD, though all LCD-screens are based on TFT active matrix addressing.
TFT LCDs are used in television sets, computer monitors, mobile phones, handheld video game systems, personal digital assistants, navigation systems, projectors, etc.

The mikroC PRO for AVR provides a library for working with the following display controllers :

Himax HX8347D and HX8352A,
Solomon Systech SSD1963,
Sitronix ST7789V,
Ilitek ILI9340, ILI9342 and ILI9481.

Note :

When connecting the TFT display to the MCU use voltage translators from 5V to 3.3V (if MCU is a 5V device). In any other case you can damage the TFT!
All display controllers are initialized with 65,536 colors (R(5),G(6),B(5)) and require two full ports for operation (due to the 16-bit interface).
