I'm trying to get information through the FPGA on MyRIO 1900. So I have two different programs running, one that gets the analog inputs and puts the results in the FIFOs and the other on my PC that get this information and display's it at an intensity graph. What I'm trying to do is similar to a pressure map, and I need this information in real-time, the same reason I'm using the FPGA. Although the problem is, I have a delay and I don't know why. Some informations: I have five FIFOs, 4 for the analogs and one with the information of which column I'm at (to build a matrix); The length of these FIFOs is 1024 (the minimum), but I'm requesting just one and the time out is set at 320 uSec (250 the loop of my FPGA and 70 for the conversion Digital/Analog). I want to touch and displays at the same time. My code is going to be below.
