Hi Alessandro, In order to save all the values read from the AD in a sampling rate of 2us with 1 channel, you should implement this function in assembly. If you use the SDK Interrupt Handler with CDW5.x it takes 1-2us just for the Interrupt-Handler -Overhead. So just this interrupt will use more or less 100% CPU Ressources. regards Christian Brauchli Manager R&D _________________________________________________________________ Brauchli Netsolution Berg Tel. +41 / 71 638 00 45 Industrial Electronic Fax. +41 / 71 638 00 46 Bahnhofstrasse 7 Mobile. +41 / 78 616 22 14 CH- 8572 Berg email.

Is it possible to minimize C code that control the A/D interrupt routine( to read the FIFO) in order to manage interrupt priority( and the interrupt time)? Ciao .
