Just read the online doc and update any graphics lcd.
I have some code. But I can't remember how complete or functional it is.
This is for the epson sed 1335. should be close.
| Code: |
/////////////////////////////////////////////////////////////////////////
//// c:\program files\PICC\drivers\LCD_epson1335.c ////
//// This file contains drivers for using a Epson SED1335 controller ////
//// in parallel/8080(intel) mode. The SED1335 is 320 pixles across ////
//// and 240 pixels down. The driver treats the upper left pixel 0,0////
//// ////
//// glcd_init(mode) ////
//// * Must be called before any other function. ////
//// - mode can be ON or OFF to turn the LCD on or off ////
//// ////
//// glcd_pixel(x,y,color) ////
//// * Sets the pixel to the given color. ////
//// - color can be ON or OFF ////
//// ////
//// glcd_line(x1,y1,x2,y2,color) ////
//// * Draws a line from the first point to the second point ////
//// with the given color. ////
//// - color can be ON or OFF ////
//// ////
//// glcd_rect(x1,y1,x2,y2,fill,color) ////
//// * Draws a rectangle with upper left point (x1,y1) and lower ////
//// right point (x2,y2). ////
//// - fill can be YES or NO ////
//// - color can be ON or OFF ////
//// ////
//// glcd_bar(x1,y1,x2,y2,width,color) ////
//// * Draws a bar (wide line) from the first point to the ////
//// second point. ////
//// - width is the number of pixels wide ////
//// - color is ON or OFF ////
//// ////
//// glcd_circle(x,y,radius,fill,color) ////
//// * Draws a circle with center at (x,y) ////
//// - fill can be YES or NO ////
//// - color can be ON or OFF ////
//// ////
//// glcd_text57(x,y,textptr,size,color) ////
//// * Write the null terminated text pointed to by textptr with ////
//// the upper left coordinate of the first character at (x,y).////
//// Characters are 5 pixels wide and 7 pixels tall. ////
//// - size is an integer that scales the size of the text ////
//// - color is ON or OFF ////
//// * Note - The given text is character wrapped. If this ////
//// function is used on a different size display, then change ////
//// the GLCD_COL define appropriately. ////
//// ////
//// glcd_fillScreen(color) ////
//// * Fills the entire LCD with the given color. ////
//// - color can be ON or OFF ////
