T6963C Graphic Lcd Library

The mikroC PRO for AVR provides a library for working with Glcds based on TOSHIBA T6963C controller. The Toshiba T6963C is a very popular Lcd controller for the use in small graphics modules. It is capable of controlling displays with a resolution up to 240x128. Because of its low power and small outline it is most suitable for mobile applications such as PDAs, MP3 players or mobile measurement equipment. Although small, this contoller has a capability of displaying and merging text and graphics and it manages all the interfacing signals to the displays Row and Column drivers.

Important :

ChipEnable(CE), FontSelect(FS) and Reverse(MD) have to be set to appropriate levels by the user outside of the T6963C_Init() function. See the Library Example code at the bottom of this page.
Glcd size based initialization routines can be found in setup library files located in the Uses folder.
The user must make sure that used MCU has appropriate ports and pins. If this is not the case the user should adjust initialization routines.

Some mikroElektronika's adapter boards have pinout different from T6369C datasheets. Appropriate relations between these labels are given in the table below :
