Project Origin

I bought a SED1520 based 122x32 dots graphic LCD, in order to display graphic and Chinese character. But the GB2312 coded font file(there are more than six thousands 16x16 dots Chinese characters in it) is too large(267616 Bytes) to fit the AVR's internal flash memory. So I decided to store this font in SD card.
In this project, I provide:
  1. A library to access SD/MMC card using SPI;
  2. A library to display 5x7 ascii characters, 16x16 Chinese characters, and xbm grahpics on SED1520 based 122x32 LCD.
