I am controlling the AD5372 with an mBed using SPI. To spare a lengthy discussion, I am attaching the LabVIEW VI used to control the DAC - created using LabVIEW 2010. Currently, we can output data (0 - 8 V) to 32 channels in about 8 seconds but this is much too slow. Are there any suggestions on how we can speed up this process? Ideally, we would like to output data in less than 1 second.
