MATLAB: Write 24-bit binary

fwrite precision 24-bit

Hi, I wonder if it is possible to write a binary file (ie: fwrite) with 24-bit precision in Matlab (2010b)? I use Matlab for generating a waveform which is later being read by Labview and presented through a NI 24-bit DAC (NI PCI-4461) with 200 kHz.

Thanks a lot for your support,

Pribislav

Have you tried using a specification of bit24 for the precision in fwrite() ?

Turns out the timing from block to block was around 5ms each when using the array syntax [byte, byte, byte] which I was originally unable to pickup on the oscilloscope. Since the CE was held low during this whole time the programming of the SPI devices still held. Hope this helps anyone that ran into similar issues.
