Is it possible to use the 128x64 glcd for 3d printers, but in a different sketch

-

i first realised power of arduino few months when became involved 3d printing...

i'm working on program or sketch control fans (240v relays) , measure ambient temperature.

but want create menu system, , navigate using encoder.
i have lcd perfect job, i've no idea how wire up, nor know send it.... i'm little scared of trial , error since i've read wrong wrings can lead damaged parts... i've tried looking through "marlin" firmware (3d printers) pins, i'm not seeing them... nor can see how used... see welcome screen drawn text easy edit, think menu going take lot more effort that...

please see pictures attached, , i'll try , link youtube video showing hardware in detail.

my question is, how wire hardware can display lcd?
and best place start making menu system can navigate clickable encoder control fans, change on/off temperature.
to clear, i'm not asking how program, know c pretty well, know how i'm going interact relays , temps, i'm stuck on lcd wiring, , library (if there one) menu design....

thanks

hi

i had been in contact marlin people time back. reason decided use u8glib software. lot of optimization went u8glib repo @ time 3d printer community.
however, u8glib (still) independent graphics library monochrome displays on arduino. u8glib project has advices wiring, in general have read datasheed. can give hits. looks st7920 type of display. maybe picture of other side of pcb of display answer question. if there pin, labeled psb, st7920 display.

u8glib instructions on wiring here: https://code.google.com/p/u8glib/wiki/device.

a gui lib available u8glib: m2tklib.

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
