After a reference has been created to an FPGA VI using the Open FPGA VI Reference, you can use the Read/Write Control function to read and write the values of the controls and indicators of the FPGA front panel. To have access to the controls and indicators in the front panel of your FPGA VI, you need to wire the HW Exec Ref Out terminal of the Open FPGA VI Reference to the HW Exec Ref input of the Read/Write Control function. You can have multiple controls and indicators listed in the same Read/Write Control function; they will be evaluated in descending order as they appear on the function. One feature of the Read/Write Control function is that it allows you to access more complex data, like arrays or cluster, that are located in the FPGA VI\u2019s front panel. You can use it to read whole clusters or an individual element of a cluster. If you need to read multiple elements of a cluster, read the whole cluster. On the other hand, you can write to a whole cluster, but you cannot write to individual elements of it. Finally, you should be extremely careful when using arrays: elements within an array are transmitted one by one between the FPGA and the Host, so transmitting large arrays might impact the performance of your system.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
