Hello, I was using PCIe 57xx with PCIe 1477, both are PCIe FPGA devices.
I have managed to connect these devices together with RTSI Cable, but when I make a pair of simple FPGA code to read/write RTSI port, nothing seems to happen?
I don't know it is because I have failed writing or failed reading? Or is the problem come from PCIe 1477 or PCIe 5763? Anyone can give me some advice?
I really appreciate any help you can provide.
The RTSI reading/writing code is actually simple, I only put these IOs in SCTL and make R/W operation there.
I also had a photo of how these two cards connected, the connection seems right to me.
Never mind, I already know what's going on there, FPGA code alone is not enough to access RTSI port, I also need to access FlexRIO API v1 to routing source to RTSI in host VI.
