Ecrans LCD et OLED

Les écrans sont pilotables par l’Arduino en fonction de la puce qui les équipe

Informations sur les écrans et l’Arduino : http://riton-duino.blogspot.com/2018/09/lcd-tft-et-arduino.html

Exemple d’utilisation de l’écran 1,44 » couleur : https://www.electronics-lab.com/project/using-1-44-color-tft-display-ili9163c-arduino/

Cf. ce tutorial : http://www.arduino.cc/en/Tutorial/LiquidCrystal pour écran « 16 PIN »

Libraire à utiliser : Liquid Crystal

Exemple utilisé avec une Arduino NANO (changement de la redéfinition du caractère 0 en 5 !) :

 /*  
  LiquidCrystal Library - Custom Characters  
  Demonstrates how to add custom characters on an LCD display.   
  The LiquidCrystal library works with all LCD displays that are   
  compatible with the Hitachi HD44780 driver. There are many of   
  them out there, and you can usually tell them by the 16-pin interface.  
  This sketch prints "I <heart> Arduino!" and a little dancing man  
  to the LCD.  
  The circuit:  
  * LCD RS pin to digital pin 12  
  * LCD Enable pin to digital pin 11  
  * LCD D4 pin to digital pin 5  
  * LCD D5 pin to digital pin 4  
  * LCD D6 pin to digital pin 3  
  * LCD D7 pin to digital pin 2  
  * LCD R/W pin to ground  
  * 10K potentiometer:  
  * ends to +5V and ground  
  * wiper to LCD VO pin (pin 3)  
  * 10K poterntiometer on pin A0
