'rx_buffer' was not declared in this scope

Have redone over 5 times and always getting " 'rx_buffer' was not declared in this scope " .
Now i tried printer Factory marlin from their site and same " 'rx_buffer' was not declared in this scope " .
Dont know what to do im so lost.

Factory printer had MKS Base V1.4 that broke Now i upgraded to MKS Gen L V1.0 . changed the Config.h file

// The following define selects which electronics board you have.
// Please choose the name from boards.h that matches your setup
#ifndef MOTHERBOARD
#define MOTHERBOARD BOARD_MKS_GEN_L
#endif

and

#define SERIAL_PORT 4

ERROR that im getting

#define SERIAL_PORT 4

This is the serial port on the controller, not the serial port on your computer. 0 through 3 are valid options on a controller with a atmel 2560.
unless you are doing something like serial over bluetooth or deliberately not using the usb port you should not change this from 0

Yes Thank you . got the code uploaded but the lcd screen isnt turning on maybe i have to flash the board due to my previous attempts?

Edited 2 time(s). Last edit at 08/04/2018 12:28AM by KaurG.

using RepRapDiscount Smart Controller . I tried adding U8glib.h and U8glib.cpp files but U8glib.cpp gives me some kind of error ... what i understand it doesent support the board`

Edited 1 time(s). Last edit at 08/04/2018 12:46AM by KaurG.

Main question is - does the code overwrite or just adds up ?

Okay, so I added U8lgb.h File and #include to Configuration . lcd not working (IF i turn the knob board will flash blue and when i turn the knob and hold it down buzzer will start sceaming)
here is SS:

New code replaces old code completely, data in eeprom may survive... depends on a few factors. (data saved with m500 commands)

your adding the lcd wrong...

you find the appropriate section for your lcd in configuratio.h and enable it (by removing the // that comments out that device)

since you keep talking about U8lgb im going to presume you have GLCD

most common is

//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

change to

#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

now you have to add the U8glib to the arduio IDE, any tutorial that says copy files.... is old and out of date

Make sure you have removed any U8glib file you tried to add previously.

Go to [github.com] and click clone or download. Then select Download Zip. Take note where you save this.

Open up arduino IDE find in the menus Sketch > Include Library > Add zip library

Find where you downloaded the library to before and add it.

Compile the code and upload it to the controller

No Errors but No lcd aswell. I did all u said but didnt find //#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER So i just added it on top of the configuration.h without the slashes.

I thought i needed U8lgb ? idk only thing i know of

Edited 4 time(s). Last edit at 08/04/2018 03:51AM by KaurG.

i will save the Config.h and try to edit another Marlin

just adding things in like that wont help... If there is no define there is probably no code to support it either'

If is not there Its not a current version of marlin

Start with a fresh current marlin might be an idea...
[github.com]

Error when trying to add zip to new Marlin : A library named U8glib_Arduino-master already exists

means the library is already installed.

yes sure but nothing has changed

Sill stuck at the same point LCD not working

Edited 1 time(s). Last edit at 08/04/2018 05:43AM by KaurG.

BUT the thing is that they have listed
THIS #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER AM I GONA BUY THIS?
BUT I HAVE THIS #define REPRAP_DISCOUNT_SMART_CONTROLLER

i tried Putting #define REPRAP_DISCOUNT_SMART_CONTROLLER BUT same thing AgiN

Edited 1 time(s). Last edit at 08/04/2018 06:02AM by KaurG.

what type of LCD do you actually have?


Does it looks like this with a more sqaure screen?


Or more rectangular like


or something else?

UGH The " more rectangular like "

Edited 1 time(s). Last edit at 08/04/2018 06:04AM by KaurG.

For the normal 2004 lcd you need to enable

#define REPRAP_DISCOUNT_SMART_CONTROLLER

and disable

//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

the 2004 lcd does not need glcd library, but it wont matter that you added it.

thats what i did but still same Thing i see no hope

Edited 1 time(s). Last edit at 08/04/2018 06:07AM by KaurG.

post your configuration.h file (preferably to something like paste bin) and link to it, so I can see

also take a picture of how you have it connected, showing the lcd connectors and where they go
