Marlin compile error when enabling ULTRA_LCD define with Megatronics 2.0

Hi All,

I am trying to compile Marlin for my Megatronics V2.0 and have been successful until I try to enable an LCD. All I want at the moment is a 16x2 display to give basic information (as I have a 16x2 display handy). I am struggling as when I enable the ULTRA_LCD define I get the following compilation error:

ultralcd.cpp: In function 'void lcd_init()':

ultralcd.cpp:835: error: 'DIOSHIFT_EN_PIN' was not declared in this scope

in the lcd_init():

...
    WRITE(SHIFT_LD,HIGH);
  #endif
#else
    pinMode(SHIFT_CLK,OUTPUT); <-- This is where the error appears
    pinMode(SHIFT_LD,OUTPUT);
    pinMode(SHIFT_EN,OUTPUT);
    pinMode(SHIFT_OUT,INPUT);
    WRITE(SHIFT_OUT,HIGH);
    WRITE(SHIFT_LD,HIGH); 
    WRITE(SHIFT_EN,LOW);
#endif//!NEWPANEL

Anyone have an idea?

Uncomment these lines in Configuration.h:

#define REPRAPWORLD_KEYPAD
#define REPRAPWORLD_KEYPAD_MOVE_STEP 10.0 // how much should be moved when a key is pressed, eg 10.0 means 10mm per click

Edit:

The setting above works only with RAMPS (MOTHERBOARD 33)!
For Megatronics (MATHERBOARD 701) as far you don't use the Keypad comment this code in ultralcd.cpp:

#else
    // pinMode(SHIFT_CLK,OUTPUT);
    // pinMode(SHIFT_LD,OUTPUT);
    // pinMode(SHIFT_EN,OUTPUT);
    // pinMode(SHIFT_OUT,INPUT);
    // WRITE(SHIFT_OUT,HIGH);
    // WRITE(SHIFT_LD,HIGH);
    // WRITE(SHIFT_EN,LOW);
#endif//!NEWPANEL

Still doing conflicting declaration error 'volatile uni16_t buttons'

In file included from ultralcd.cpp:34:
ultralcd_implementation_hitachi_HD44780.h:12: error: conflicting declaration 'volatile uint16_t buttons'
ultralcd.h:30: error: 'buttons' hsa a previous declaration as 'volatile uint8_t buttons'.

help please.!

The trouble with Marlin is that the source is modified quite often!
I would migrate to Repetier-Firmware:

Keypad and LCD Add-on

3D Printing :: bit-by-bit - Thingiverse

Have the same issues, and migrating aint no option, must be someone who can help
i have problems with ramps 1.4, 20x4 lcd and reprapworld keypad, when i take another firmware (not the latest) no problems, but when i take the latest official, the i also get the in file included from ultralcd.cpp:34:
ultralcd_implementation_hitachi_HD44780.h:12: error: conflicting declaration 'volatile uint16_t buttons'
ultralcd.h:30: error: 'buttons' hsa a previous declaration as 'volatile uint8_t buttons'.

and i cant figure it out, as i dont have much programming experience.

Mendelmax 1.5, E3D v6, ramps 1.4, drv8825, kapton heated bed (working)

Sparkcube 1.1 XL, radds 1.5, raps128, lcd, fsr autobed, octoprint on odroid (building)

I have the same issue with the latest download. Shift_clk not defined and whole host of other errors when Ultra_LCD is defined.

ULTRA_LCD currently needs some sort of encoder to make the menu system work and you are falling into the default case. Try defining NEWPANEL (and ULTIPANEL) in Configuration.h per the #ifdef around [github.com]

I recently posted a patch at [github.com] that tests if no encoder is defined and lets it compile without those two defines, which provides basic output-only LCD support, .

#define ULTIMAKERCONTROLLER //as available from the ultimaker online store.
#define ULTIPANEL //the ultipanel as on thingiverse

define both of these
