Fifo - ICP DAS USA I-8014W User Manual

FIFO

The I-8014W is equipped with a 4 k sample of FIFO which may store 4096 samples of
data from Magic Scan to guarantee no data loss. The acquisition data is saved into
the FIFO one by one in the scan process. We have to read back data from the FIFO
in time to avoid FIFO filled; if the FIFO is filled, the data can not be saved again until a
FIFO clear command is executed. On the other hand, if we read data from FIFO too
frequently, it will waste CPU time and reduce the performance. To get the best
balance, we provide two modes to transfer data from FIFO, one is by polling and the
other is by interrupt.
