Transmiss a big array to DRAM

[OliverZT]

Hello, experts

I want to transmiss a big array (512×512×32) to DRAM. My device is Ni 7962R. I notice that example 'High Throughput Streaming' transmit data by TDMS file. But, how can I convert mat file to TDMS file?

Hi. I just do some quick search and found out that to convert mat file to TDMS file in LabVIEW, you need to:

1) Read the mat file in LabVIEW

2) Write the data into TDMS

The first part can be achieved by using DataPlugins and more details about DataPlugin can be found at here.

Meanwhile, the second part can be done easily in LabVIEW. This reference should be a good guide for you.

All the best 😉

For DRAM, see these examples:
