Je me suis acheté un petit écran LCD (sur Adafruit.com, très bon site de matos type Arduino)
Ce petit écran est branché en USB sur mon ordinateur portable sous Windows.
Je partage cette modeste expérience pour ceux qui voudrait jouer un peu avec ce type de périphériques (vraiment pas très cher).

J'ai installé le pilote qui va bien - voir ici :

Ensuite, je vous partage une include qui facilite beaucoup la programmabilité du LCD via PureBasic :
