Documentation

C'est un nouveau format ASCII nommé Component Interchange Format (CXF). Chaque composant électronique utilisé avec PCBs peut être défini selon ce format. Il est facile à comprendre et, par ce moyen, il peut être facilement adopté / utilisé par toute personne ayant le besoin d'échanger des données de CAO électronique.

Une bibliothèque a des composants différents. Un composant peut avoir des symboles différents (au moins un) et normalement un boîtier. Une résistance a un symbole, un IC logique peut avoir pleusieurs symboles (portes).

Un symbole et un boîtier sont composé de plusieurs primitives graphiques telles que des lignes, des textes, des rectangles et des broches dans les symboles et des pastilles dans les boîtiers. Chaque primitive est écrit dans le texte et la ligne commence avec un identifiant. Plusieurs champs prédéfinis peuvent suivre. Chaque primitive peut également avoir plusieurs propriétés définies par l'utilisateur, chaque bien écrit dans une propre ligne. Les propriétés ne contiennent pas de CR /LFs , mais elle peut être longue extraordinaire (100000 + Octets). La possibilité de propriétés définies par l'utilisateur pour chaque primitive rend le format très avenir.

Vous devez faire un autre conversion sur base de données.

La SYNTAXE du format: (seulement en anglais)
