Hi, I'm new to this newsgroup, and also a relative FPGA newbie (though have lots of hardware and software experince). If I should need the FAQ, please kindly point me in the right direction. I would like to implement a minimal RS232 interface on my Cyclone device. I only require TxD and RxD signals (I've got an RS232 level- shifter IC on board). I only require a bare-bones implementation...

Hi, I am trying to connect my Spartan 3 borad with PC by RS232 , and am able to echo single input in hyper temial consol. What i am trying to do is sending "hi" from the board to the pc, by only hit 1 from hyper termial. Will follow steps design work? I am not sure if the RS232 (hypertermial) has any limitation on this. I have worked on this for sevral days, but still doesn't work. any idea...

Hello all, Some time ago with an older version of the EDK (v6 I think) there was a ML300 design that would simulate the entire SoC, and included a hook into a local terminal window that would talk over the simulated SoC rs232 serial port. For example, you could build a system in the EDK that runs an executable on the PPC that would echo the characters it receives over RS232. That i/o was...

Hi, I have implemented the Aurora protocol on the V2PRO FF672 FPGA. As part of testing, I need to access the TX data on the aurora links through RS232 interface as well. Now the problem I have is that the avbl project in XPS has a rx and tx port (std_logic) and the data I need to send is atleast 16 bits. How do I access or interface the register outputs from Aurora to RS232?? Thanks, Vive...

Hello All, I have started using Xilinx Spartan3E 1600E Microblaze Development Board and want to use its RS232 facility in my project. This board has two RS232 connectors but I cannot figure out what UART it uses. I was searching for UART chip on the board (I was actually searching for a MAXIM chip) and have seen none. The Xilinx board's manual (ug257) does not say what particular UART is ...

Hello, I have built an Application Note for newbies (& students !) who want to understand and implement RS232 (UART) in an FPGA. Especially when it's an assignement, they should follow this document instead of asking for the UART code (which I give away only in the context of larger educational projects). I have also built a nice (I think) Tutorial to implement and test a simple UART i...

I've been pondering... When it comes to attaching an FPGA to a PC, there are lots of options. First there's JTAG, then there's RS232, then there's ethernet, and PCIe. But there's an elephant in this room: why is USB on FPGA so hard? Sure, every FPGA can be connected to a PC with USB, but it's usually through a dumb bridge chip that does RS232, or maybe uses USB to bitbang JTAG. USB2 i...
