Cette carte est une refonte compl\u00e8te du circuit de d\u00e9monstration original. Plusieurs options de traitement du signal sont propos\u00e9es pour la sortie analogique et les signaux num\u00e9riques peuvent \u00eatre g\u00e9n\u00e9r\u00e9s par une ou plusieurs cartes de d\u00e9veloppement \u00e0 FPGA, faciles d\u2019utilisation et de co\u00fbt r\u00e9duit. Un exemple de code FPGA est fourni, qui g\u00e9n\u00e8re les donn\u00e9es d\u2019un signal sinuso\u00efdal num\u00e9rique pour le CNA.<\/p>\n

Des cartes de d\u00e9monstration pour composants \u00e0 semiconducteurs permettent une synergie entre la communaut\u00e9 des r\u00e9alisateurs\u2009(Maker) et des concepteurs en production. Un CNA 50 M\u00e9ch.\/s requiert une configuration de carte soign\u00e9e et une source de signal num\u00e9rique qui lui convient. Un g\u00e9n\u00e9rateur num\u00e9rique de mod\u00e8les est l\u2019outil de choix, mais c\u2019est une option co\u00fbteuse si l\u2019utilisateur n\u2019en poss\u00e8de pas un et qu\u2019il n\u2019a qu\u2019un CNA \u00e0 \u00e9valuer. Heureusement, il existe des cartes provenant de la communaut\u00e9 des r\u00e9alisateurs qui procurent le m\u00e9lange ad\u00e9quat de possibilit\u00e9s, faciles d\u2019utilisation et \u00e0 bas co\u00fbt.<\/p>\n

Les cartes comme la DC2459A procurent \u00e0 la communaut\u00e9 de r\u00e9alisateurs l\u2019acc\u00e8s \u00e0 des composants \u00e0 performances r\u00e9ellement tr\u00e8s \u00e9lev\u00e9es, des exemples de codes et \u00e0 une configuration de carte de PC pour des projets et l\u2019\u00e9laboration de prototypes.
\nUn des connecteurs num\u00e9riques de cette carte est exactement compatible avec la carte \u00ab\u00a0Mojo\u00a0\u00bb Spartan 6 FPGA de Embedded Micro. Cette derni\u00e8re poss\u00e8de un processeur ATmega32U4 avec un logiciel de d\u00e9marrage Arduino, procurant des options de contr\u00f4le du CNA 16 bits ou en exploitant le code Linduino pour ajouter des fonctionnalit\u00e9s suppl\u00e9mentaires au signal analogique mix\u00e9.<\/p>\n
