Hi everyone... I wonder if there is any simple way to send the data from a block-ram to the RS232-interface, without the need to write all the RS232 VHDL-code myself! Thanks everyone!

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 all I am using Altera DE0 Cyclone III board. I am confused about the RS232 connection in DE0 Cyclone II. my question is that: There are some connection in FPGA board related to the RS232. Dose it mean that there is a transceiver in the DE0 board or I should connect it to a tranceiver? Regards

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...

Hi Group I am trying to find a board with Xilinx V2 pro having A/D converter module, Irda module , RS232 module etc. My application is Intelligent Robotics. I am having xilinx V2pro HW AFX board, Memec Insight V2pro board, so any daughter modules with A/D, IrDa, Rs232 etc.. is another product I am looking for. Any help would be appreciated Thank you n advance Ram

Does anyone know if there's a ready-to-use rs232 uart in vhdl for the Virtex-II pro fpga? We have done some designs in ISE, and hope to display results in a terminal window. Thanks.

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 ...

Hallo, I have a spartan 3 starter board. I have implemented a small microcontroller based on microblaze. I would use the rs232 of the board as stdin and stdout. I have configured it into edk. What software should I use into pc to send/ receive datas? I have tried Hyperterminal, but it seems it doesn't connect. Many Thanks Marco

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...

Hello! I have been playing with image processing on FPGA for some time now, and the results seem interesting (I am working mainly on image preprocessing and edge/corner detection algorithms). My main research platform was the S3BOARD from Digilent/Xilinx, but I got to the point, where RS232, or RS232 USB converters do not offer sufficient speed (imagine sending a 512x512 image to the b

need to know where to start to get RS232 comm's working, and the led's blinking. I was kinda hoping when I opened the box to my new XUPV2P: http://www.xilinx.com/products/devkits/XUPV2P.htm there would be some basic, hello world programs templates to play with, and a demo program so that I could have the board send and receive messages on the DB9 connector. I can't seem to locate any...

Hi, All The ChipScope gave me the message "Waiting for core to be armed" while the program can run on the board at the same time. I have a small test project which includes a MicroBlaze with a DCM, a RS232 interface and other necessary components. The DCM divides the input clock from 100MHz to 50Mhz. An application prints out something through the RS232 will be shown on the hyperterminal. ...

Hi All, We are developing a product which uses a Cyclone2 device from Altera. The unit is a completely sealed unit with only a RS232 link to the outside. We want to be able to update the Cyclone2 configuration files stored in a EPC device using the available RS232 link. Has anyone done something similar out there? I have thought of writing a PC application which would serially send the ...
