Epson S1D13700 Graphic Lcd Library
The mikroC PRO for PIC32 provides a library for working with Glcds based on Epson S1D13700 controller.
The S1D13700 Glcd is capable of displaying both text and graphics on an LCD panel. The S1D13700 Glcd allows
layered text and graphics, scrolling of the display in any direction, and partitioning of the display into multiple screens.
It includes 32K bytes of embedded SRAM display memory which is used to store text, character codes, and bit-mapped
graphics.
The S1D13700 Glcd handles display controller functions including:
- Transferring data from the controlling microprocessor to the buffer memory
- Reading memory data, converting data to display pixels
- Generating timing signals for the LCD panel
The S1D13700 Glcd is designed with an internal character generator which supports 160, 5x7 pixel characters in
internal mask ROM (CGROM) and 64, 8x8 pixel characters incharacter generator RAM (CGRAM).
When the CGROM is not used, up to 256, 8x16 pixel characters are supported in CGRAM.
