Problème Atmega8

-

bonsoir,

je suis entrain de réaliser un circuit base d'atmega8 en version tqfp. j'ai fais mon schéma, mon typon et grave le circuit.
je l'ai soudé, je le branche et j'envoi le code "fade" ça marche mais lentement donc je fais graver la séquence d'initialisation (j'ai sélectionné atmega8 dans type de cartes) la le code ce lance normalement.

j'envoi un autre code et la plus rien ne marche. la led ne s'allume plus, mais quand j'envoi du code sur la carte la led brille légèrement (pas normal du tout).
edit@4h07 : la plus rien ne fonctionne, latmega chauffe légérement autant que l'arduino. plus de communication en isp ca me renvoi une erreur tout les coups. je pense un atmega hs mais alors comment? :/

je joins le schéma, typon et 2 photos ( le atiny85 et 12v etc sur le circuit fini est une erreur de ma part :/ )

en tout cas merci pour votre aide.

as tu fais une vérification de tes tensions d'alimentation?

Multithumb configuration params not working? - Joomla! Forum - community, help and support

hi, i've installed multithumb 1.1 on joomla 1.011 site , works fine in basic set-up (and jce-editor). except when try tweaking mambot params, things stop working. specifically: if use "only in these categories" setting , fill in categoryname, e.g. "news", pop-ups/thumbnails stop working, categories, including "news". if use "not in these categories" these categories still use pop-ups. if select "use thumbnails" "no" not no thumbnails no pop-ups anymore. so way use multithumb selectively use optioni "apply content {multithumb}", bit cumbersome. there more people having these issues? hi bikey, i having issues bit different - yet same.  saying have way set configuration plug-in.  not know how find cong this.  if can maybe read posting - don't bore process.  jce editor - have not installed - still using default html editor - cant recall name.  why not see config file? anyway - find if use static page , pass com...
