Setare Marlin pentru LCD functional

Salut baieti. Am o problema cu setarea marlin-ului pentru a-mi functiona LCD-ul. LCD ul este acesta: [www.aliexpress.com] . Ca si placa de baza folosesc un miniRambo. Am pus o poza ca sa vedeti problema. Acest LCD l-am probat pe o pusa i3 originala si funtioneaza perfect. Exact cum am facut conexiunile cand am conectat LCD-ul la prusa, asa le-am facut cand le-am conectat si la placa mea. Deci nu se pune problema de inversat firele intre ele sau sa le fi conectat invers la 180 grade. Apoi am conectat LCD-ul de la prusa la miniRambo a meu si exact aceasi lucru imi arata. Asta imi da de inteles ca problema e strict de firmware, din Marlin. Mai jos va atasez fisierul Configuration.h sa vedeti cum am facut setarile:

// LCD LANGUAGE
//
// Here you may choose the language used by Marlin on the LCD menus, the following
// list of languages are available:
// en, an, bg, ca, cn, cz, de, el, el-gr, es, eu, fi, fr, gl, hr, it,
// kana, kana_utf8, nl, pl, pt, pt_utf8, pt-br, pt-br_utf8, ru, test

#define LCD_LANGUAGE en

//
// LCD Character Set
//
// Note: This option is NOT applicable to Graphical Displays.
//
// All character-based LCD's provide ASCII plus one of these
// language extensions:
//
// - JAPANESE ... the most common
// - WESTERN ... with more accented characters
// - CYRILLIC ... for the Russian language
//
// To determine the language extension installed on your controller:
//
// - Compile and upload with LCD_LANGUAGE set to 'test'
// - Click the controller to view the LCD menu
// - The LCD will display Japanese, Western, or Cyrillic text
//
// See [github.com]
//
// :['JAPANESE','WESTERN','CYRILLIC']

//
// LCD TYPE
//
// You may choose ULTRA_LCD if you have character based LCD with 16x2, 16x4, 20x2,
// 20x4 char/lines or DOGLCD for the full graphics display with 128x64 pixels
// (ST7565R family). (This option will be set automatically for certain displays.)
//
// IMPORTANT NOTE: The U8glib library is required for Full Graphic Display!
// [github.com]
//
#define ULTRA_LCD // Character based

//
// SD CARD
//
// SD Card support is disabled by default. If your controller has an SD slot,
// you must uncomment the following option or it won't work.
//
#define SDSUPPORT

//
// Uncomment ONE of the following items to use a slower SPI transfer
// speed. This is usually required if you're getting volume init errors.
//
//#define SPI_SPEED SPI_HALF_SPEED
//#define SPI_SPEED SPI_QUARTER_SPEED
//#define SPI_SPEED SPI_EIGHTH_SPEED

//
// SD CARD: ENABLE CRC
//
// Use CRC checks and retries on the SD communication.
//
//#define SD_CHECK_AND_RETRY

//
// ENCODER SETTINGS
//
// This option overrides the default number of encoder pulses needed to
// produce one step. Should be increased for high-resolution encoders.
//
//#define ENCODER_PULSES_PER_STEP 1

//
// Use this option to override the number of step signals required to
// move between next/prev menu items.
//
//#define ENCODER_STEPS_PER_MENU_ITEM 5

/**
* Encoder Direction Options
*
* Test your encoder's behavior first with both options disabled.
*
* Reversed Value Edit and Menu Nav? Enable REVERSE_ENCODER_DIRECTION.
* Reversed Menu Navigation only? Enable REVERSE_MENU_DIRECTION.
* Reversed Value Editing only? Enable BOTH options.
*/

//

//
// If CLOCKWISE normally moves DOWN this makes it go UP.

//
// SPEAKER/BUZZER
//
// If you have a speaker that can produce tones, enable it here.
// By default Marlin assumes you have a buzzer with a fixed frequency.
//
//#define SPEAKER

//
// The duration and frequency for the UI feedback sound.
// Set these to 0 to disable audio feedback in the LCD menus.

Orice sfat imi poate fi de ajutor. Daca are cineva o imprimanta cu lcd functional il rog sa posteze conf.h sa pot compara.

Configuratia pare buna, ce ai tu e un display cu 4 randuri, pare a fi "#define REPRAP_DISCOUNT_SMART_CONTROLLER"

poti incerca:

1. inversaza cablurile ( sa verifici cablurile)
2. inverseaza conexiunile (sa fii sigur ca nu ai inversat LCD cu SD)
3. testeaza LCD_ul pe alta imprimanta/ alt montaj. Inclusiv incarca orice alte firmware-uri care sa faca LCD-ul sa afiseze ceva coerent.
4. poti sa mai incerci si alte optiuni din fisierul de configurare...
