bonjour a tous,
donc, j’ai un petit soucis avec un clavier 4x3 que j’essaie de faire marcher.
il ressemble en tout point a ça, mais avec 9 pin:
je n’ai aucune référence du clavier, pas même son nom, il a 9 pin, et après avoir fais des test au multimètre, j’ai:
1 2 3| 7
4 5 6| 5
7 8 9| 3
#0 *| 1
2 4 9
8
donc, mon problème est que, toutes les touches marchent, sauf le 1 et le 4, alors qu’au multimètre, ils correspondent bien.
voici le code dans lequel je l’utilise:
#include <Wire.h>
#include <LCD.h>
#include <LiquidCrystal_I2C.h>
#include <Arduino.h>
#include <TM1637Display.h>

#define I2C_ADDR 0x3F
#define BACKLIGHT_PIN 3
#define En_pin 2
#define Rw_pin 1
#define Rs_pin 0
#define D4_pin 4
#define D5_pin 5
#define D6_pin 6
#define D7_pin 7
#define CLK 10
#define DIO 11

niveau branchement, j’ai donc mis les pin:
7 sur sortie 9
5 " " 8
3 " " 7
1 " " 6
2 " " 2
4 " " 3
9 " " 4
ais-je fais un mauvis branchement? une mauvaise déclaration?
ce qui me bloque, c’est le fait que le 7 et le # marchent, alors que ça marche par colone/ligne 
merci d’avance!
