When using the RepRapDiscount Full Graphic Smart Controller, there are some possible hacks to modify the display.

Display of just one extruder

(THIS APPLIES TO MARLIN V1.0.0-RC2! Other versions may require a different approach.)

To remove the second and third extruder display from the info screen, two files have to be modified:

DOGMbitmaps.h

In this file some lines have to be changed in the variables "status_screen0_bmp" and "status_screen1_bmp": 

const unsigned char status_screen0_bmp[] PROGMEM = { //AVR-GCC, WinAVR

};


dogm_lcd_implementation.h

In this file, you first have to find the lines 

u8g.setPrintPos(31,27);
u8g.print("---");

replace them by 

u8g.setPrintPos(31,27);
u8g.print("   ");


Now find the lines 

u8g.setPrintPos(55,27);
u8g.print("---");

replace them by 

u8g.setPrintPos(55,27);
u8g.print("   ");

That's it, no more unessesary extruders on that info screen.

Modified info screen


(THIS APPLIES TO MARLIN V1.0.0-RC2! Other versions may require a different approach.)

In dogm_lcd_implementation.h you can change the lines below 

const unsigned char start_bmp[574] PROGMEM = { //AVR-GCC, WinAVR

to a new logo. The comma seperated values are the binary pixel information in hexadecimal format, one byte at a time. The logo image has a size of 60x64px. One possible way to get a new logo is to download the software LCD Bitmap Converter [[1]]. With it's help, you can load a bitmap file and convert it to the pixel informations. There are some [[2]] other tools [[3]] designed to do the same.

When you have your own logo converted, it seems to be important to break lines after every 8 numbers. As soon as you have done that, you can copy these numbers in the dogm_lcd_implementation.h, overwriting the old contents of start_bmp. Note, that it not important to convert the numbers to hex, decimal works fine. An example for a custom logo follows. 

const unsigned char start_bmp[574] PROGMEM = { //AVR-GCC, WinAVR
