Thanks for the help. My VI sends register and memory content to an IC using SPI.
Here is a screenshot of the 2nd sequence of my VI. The sequence right after is the exact same but I load a different file. The 1st, 4th and 5th sequences send hardcoded data to the SPI programmer no arrays involved. That's it. Run the whole thing once, you're fine. Try to do it again, array is filled with zeroes.
the file being loaded in the beginning is of the following structure
0xXX, 0xXX, 0xXX, .... where XX is a HEX representation of a byte.
Thanks again
