GLCD Development Board

Our GLCD Development Board is designed to jump start graphical LCD programming for people who do not have any previous experience in the field. The hardware is tightly integrated with all our tutorials and the ProGFX driver. The user should have a basic knowledge of C programming (with little experience of avr-gcc) , that it! Everything related to Graphical LCD is explained in the user manual.

NOTE: You need a ISP Programmer like USB AVR Programmer to upload code to this board. This is NOT included with the board.

About ProGFX.org

Character LCD Interfacing is quite easy so every one uses it, but when I comes to Graphic LCD you need a well written and powerful graphic library. Its not enough that you read the LCD datasheet and connect it your MCU and start sending data. Because the LCD just appears to be block of memory whose contents are directly visible on screen. The datasheet can only guide you how to access this memory. You just can't do much by writing to the memory. The graphic library is a piece of software that has complex algorithms to render graphic primitives like line, rectangles, circles, images and more. It also helps load fonts which is used to render text and numbers on screen. So it provide high level access to the LCD screen and applications can be written much more easily.

ProGFX is one such Powerful but easy to use C library to program Common Graphical LCDs.

Features includes :-

• Line Drawing
• Rectangle Drawing
• Filled Rectangle Drawing
• Circle Drawing
• Image/Icon Drawing
• Text Drawing
• Number (Integer Drawing)
