Go small!

This has been a great way to let me make small (size and complexity) projects while challenging efficiency of design. If your code uses libraries you will likely need to find ATtiny85 specific libraries such as TinyWire and Tiny4kOLED since there really isn't a lot of space on the chip. In looking up how to program this microcontroller I found that I had to combine this information in about 3 tutorials (each one seemed to leave a different step out) and then browse through forum questions to get the last bit. Look into a pre-made programmer, I've made a board that plugs into an UNO that's been programmed as a programmer.

Allez petit !

Cela a été un excellent moyen de me permettre de réaliser de petits projets (taille et complexité) tout en défiant l'efficacité de la conception. Si votre code utilise des bibliothèques, vous devrez probablement trouver des bibliothèques spécifiques à ATtiny85 telles que TinyWire et Tiny4kOLED car il n'y a vraiment pas beaucoup d'espace sur la puce. En cherchant comment programmer ce microcontrôleur, j'ai découvert que je devais combiner ces informations dans environ 3 tutoriels (chacun semblait laisser une étape différente), puis parcourir les questions du forum pour obtenir le dernier bit. Regardez dans un programmeur préfabriqué, j'ai créé une carte qui se branche sur un UNO qui a été programmé en tant que programmeur.
