Cours ou livre sur la programmation avancé Arduino

Bonjour,

Plus j'avance dans mon projet et plus je découvre que je dois maîtriser vraiment à fond le C++ qui se cache derrière l'environnement Arduino

Avez-vous un bon cours ou un bon livre à me recommander ?

En particulier, ce que je souhaite approfondir :
- les templates
- les classes
- variables, fonctions statiques, attribus
- l'usage de l'assembleur
- l'accès au hardware

Pour illustrer mon besoin, j'ai trois fichiers venant d'une bibliothèque que j'ai commencé à optimiser mais elles utilisent massivement tout ce que je viens d'énumérer ci-dessus et que je ne maîtrise pas :

PDQ_FastPin.h

Code:

C'est déjà à la base une bonne bibliothèque, programmé par des passionnés qui maîtrisent le langage, même si j'ai réussi à améliorer encore certaines fonctions.

Je dois mieux maîtriser le langage pour aller plus loin dans mon optimisation d'une part, et surtout d'autre part pour améliorer le code de mon projet.

Je sais qu'on trouve beaucoup de choses sur Internet mais même aujourd'hui rien ne vaut un bon livre.
J'ai dépassé le stade du tutoriel pour faire clignoter une led :mouarf:, il me faut un ouvrage de référence qui va au bout des choses mais sans oublier une étape.
Etant donné le niveau que je recherche j'aimerais si possible un livre en français, pour limiter le niveau de migraine :mouarf: et que ce passe temps reste un plaisir

A bientôt
