One day I got graphic LCD from old, broken device. I didn't know much about this model except that if is black/green one. When I dug it out from silicon glue it turned out, that it had original producer label. I looked in the Internet and I found datasheet. It looked very comprehensive but also a bit complicated. I cound easly read out from it how to set up all registers. I decided, that if I finally managed to write working library for this display I will put it here to make others people life easier. This basic version contains functions:
void LCD_writeB(char Byte, char Command); void LCD_init(void); void LCD_clear_display(void); void LCD_set_y(uint8_t y); void LCD_set_x(uint8_t x); void LCD_put_c(uint8_t x, uint8_t y, uint8_t Char); void LCD_printf(uint8_t x, uint8_t y, const char *string); void LCD_image(uint8_t width, uint8_t height, uint8_t *image);
If you find it useful please download all three files. Please leave also some comment below.
