Sending Data from PC to FPGA(spartan 3 starterkit) via RS232

[chimera086]

Hi, im really new to this project and i dont know where to start. All i know is that i could use the hyperterminal for me to send data towards the FPGA... but i dont know how to do it... also the hardware stuff for the connection between the PC and FPGA... what i want is to make a simple project that sends data only towards the FPGA so that i could use that data in lighting the LEDS or something...Pls do help me... i really dont know this one...

Search this board! There have been similar kind of questions asked and replied.

What you need is a UART hardware inside your FPGA. As suggested in previously post search forum for UART.

Your application is in this book with source code.

hello zula

i have gone through this book also. i understand the functionality but i couldnt implement it. i will be really grateful if you can provide me the user constraint file for the code in the book you mentioned.

which board you are using?

which board you are using?

its XILINX digilent Spartan 3 FT256 Xc3s200 .........if you have iuts ucf for UART?

 

[zula]

you can use this link.

also you should just write like this into ucf file;

NET "RXD_Port" LOC = "T13" | IOSTANDARD = LVTTL ; # for the rx signal
NET "TXD_Port" LOC = "R13" | IOSTANDARD = LVTTL | DRIVE = 8 | SLEW = SLOW ; # tx signal

dear can you provide me uart code with this User conbstraint File? i will really appreciate if the code is in verilog. a compete running code for spartan 3. i will be really grateful to you.

regards

it is the verilog version of same books. and i will really appreciate if you are working a little more than me for your projects?

hi zula

i already have verilog version for this book and i am exactly following this book chapter 8. the UART code is copied and ther is no error in it. all i need is a user constraint file for this code.

and besides this, i was actually asking if you have any UART code that is in working condition and contains all necessary things like UCF. it could be very helpful for me.

thanks for your kind reply

Omg, UCF is not so hard to make, just read your code, usually UART codes just need RX and TX pins to be associated with your FPGA, if you figure it out by yourself you will learn a lot. Just try.
