See how the read/write control is connected to the global variables? I would like to add more variables, I've created the globals (some are shown in the picture above) but as you can see they are not available in the read/write control. How do I add them? I also tried to create a new read/write control, but as you can see that does not help. Any assistance would be appreciated.

Hi count3r5tr1ke, It looks like you are referencing a particular bitfile in the open FPGA reference. I believe that even when you save your FPGA VI, the Real-Time VI is still referencing an older bitfile. Have you tried re-compiling and referencing the new bitfile once the compilation has completed? A safe way to make sure you have the most up-to-date bitfile is to check the VI option when you right-click on the Open FPGA reference and select Configure Open FPGA Reference. When this option is checked, if you make changes to the FPGA code, it will force you to re-compile the FPGA VI before referencing it on the Real-Time side. Warm Regards,

How to add more variables to a read/write control?

Resolvido!

OK I'll try that. Does this mean I always have to be connected to the board, or only after making a big change?

No, you don't have to be connected to the board if you change the reference to the FPGA VI you keep editing. If you refer to a bitfile then you will have to compile the VI first but you still won't have to be connected.
