April 15, 2023 03:36AM
Hello,
I want to configure reprapdiscount full ldc with my creality ender5 pro.
In my mainboard (v4.4.2) ı have just 1 EXP which has 10 pin . How can I connect lcd to my mainboard?
And ı have also some problems while building the marlin 2.1 .It gives some error like define some button.
Thanks for your comments .

Firstly m going to presume you meant V4.2.2 not v4.4.2 as that doesn't exist as far as I can ascertain

You cannot connect this up without loosing the sdcard on the lcd. There are simply not enough pins.

So defining REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is not a option as you cannot have a sdcard on the display that this define expects,

You need ti instead define CR10_STOCKDISPLAY and identical lcd type and encoder, but with no sdcard

Then you going to have to make a custom wiring harness form the 10 pin plug to the lcd and rotate the pins based on where the gnds are


   *               V4.2.2 LCD port
   *                    ------
   *  BEEPER_PIN  PC6  | 1  2 | PB2 BTN_ENC
   *      BTN_EN1 PB10 | 3  4 | PB11
   *      BTN_EN2 PB14   5  6 | PB13 LCD_PINS_D4
   *  LCD_PINS_RS PB12 | 7  8 | PB15 LCD_PINS_EN
   *               GND | 9 10 | 5V
   *                    ------

to

/**                     Smart Adapter (c) RRD
     *              ------                          ------
     * BEEPER_PIN   | 1  2 |  BTN_ENC              | 1  2 | 
     * LCD_PINS_EN  | 3  4 | LCD_PINS_RS   BTN_EN1 | 3  4 | 
     * LCD_PINS_D4    5  6 |               BTN_EN2   5  6 |  
     *              | 7  8 |                       | 7  8 | 
     *       (GND)  | 9 10 |  (5V)          (GND)  | 9 10 | --
     *              ------                          ------
     *                EXP1                           EXP2
     */


But Note:

Some lcds have the ports rotated 180 degrees. You need to check where the gnd pins actually are on your ports
