Library pour écran LCD

-

bonjour,

j'essaye de gérer un écran lcd 2004 avec un arduino uno connecté en i2c.

j'ai commencé par copier/coller un code que j'ai trouvé sur la page du fournisseur. apparemment il ne reconnait pas l'instruction "liquidcrystal_i2c.h" car j'ai un message d'erreur qui dit ceci : i2c_lcd2004_sample.pde:5:31: fatal error: liquidcrystal_i2c.h: no such file or directory

j'ai du oublier quelque chose mais quoi ?

voici le code

code: [select]
//dfrobot.com
//compatible arduino ide 1.0
//library version:1.1
#include <wire.h>
#include <liquidcrystal_i2c.h>

#if defined(arduino) && arduino >= 100
#define printbyte(args)  write(args);
#else
#define printbyte(args)  print(args,byte);
#endif

uint8_t bell[8]  = {0x4,0xe,0xe,0xe,0x1f,0x0,0x4};
uint8_t note[8]  = {0x2,0x3,0x2,0xe,0x1e,0xc,0x0};
uint8_t clock[8] = {0x0,0xe,0x15,0x17,0x11,0xe,0x0};
uint8_t heart[8] = {0x0,0xa,0x1f,0x1f,0xe,0x4,0x0};
uint8_t duck[8]  = {0x0,0xc,0x1d,0xf,0xf,0x6,0x0};
uint8_t check[8] = {0x0,0x1,0x3,0x16,0x1c,0x8,0x0};
uint8_t cross[8] = {0x0,0x1b,0xe,0x4,0xe,0x1b,0x0};
uint8_t retarrow[8] = { 0x1,0x1,0x5,0x9,0x1f,0x8,0x4};
 
liquidcrystal_i2c lcd(0x27,20,4);  // set lcd address 0x27 20 chars , 4 line display

void setup()
{
//  serial.begin(57600);
  lcd.init();                      // initialize lcd
  lcd.backlight();
 
  lcd.createchar(0, bell);
  lcd.createchar(1, note);
  lcd.createchar(2, clock);
  lcd.createchar(3, heart);
  lcd.createchar(4, duck);
  lcd.createchar(5, check);
  lcd.createchar(6, cross);
  lcd.createchar(7, retarrow);
  lcd.home();
 
  lcd.setcursor(0, 0);
  for(int = 0;i < 20; i++)  lcd.printbyte(6);
  lcd.setcursor(0, 1);
  lcd.printbyte(6);
  lcd.print("   hello world    ");
  lcd.printbyte(6);
  lcd.setcursor(0, 2);
  lcd.printbyte(6);
  lcd.print("  ");
  lcd.printbyte(3);
  lcd.print(" arduinos!   ");
  lcd.printbyte(6);
  lcd.setcursor(0, 3);
  for(int = 0;i < 20; i++)  lcd.printbyte(6);
//  lcd.clear();

}

void loop()
{

}

bonjour,
ton lcd est un écran normal ou doté doté d'une inter face i2c ?
@+
de plus tu n'es pas dans la bonne rubrique ici , c'est "le bar" donc tous les délires sont possibles.
a voir avec les modos pour le déplacer dans la bonne rubrique.

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
