Spectrum Brands MC.31XX Sample format

FIFO Mode Programming

The following example shows how to sort the channel data when using 4 channels in FIFO mode:

Sample format

The sample format in FIFO mode does not differ from the one of the standard (non FIFO) mode. Please refer to the relating passage concerning

the sample format in the standard acquisition chapter.

for (i = 0; i < (lBufferSizeInSamples / 4); i++)

{

Data[0][i] = FIFOBuffer[i * 4 + 0];

Data[1][i] = FIFOBuffer[i * 4 + 2];

Data[2][i] = FIFOBuffer[i * 4 + 1];

Data[3][i] = FIFOBuffer[i * 4 + 3];

}
