    Magic Scan This chapter provides the detail of Magic Scan, the key function designed on the I-8014W for multi-channel high sampling rate analog data acquisition. At the last part of this chapter, it introduces two demo programs for implementing Magic Scan. Both the Magic Scan mode and trigger method could be selected in the two programs, the only difference is that one transfers data by polling and the other transfers data by interrupt.
