I need to develop UART transmitter in vhdl(FPGA to PC through rs232). I have the following code in verilog. Can anyone please provide the corresponding vhdl code or any other code for implementing the desired one. module transmitter1(clk,reset,transmit,data,TxD); input (...)
Hi I am facing a unusual problem when implementing a rs232 transmitter problem. I have written a vhdl script which includes a UART component form Digilent. Problem is that logically my program should send the letter 'A' then 'B' then 'C' and then 'D' and the process should repeat. But upon programming the Chip with bit file, the program transmit on
Hi.I am so sorry because of my poor English speaking! I am trying to write a simple code in vhdl for rs232 to receive data through a wire as you is my code! something is wrong! please help me to solve this challenge!thanks :) 99316 as you can see,bit_cnt pulsed twice!!!!!why? and number of "get" state must
hello everybody, I?m trying to understand how is working the rs232 controller, and I thing I have understood nearly everything, the only thing I can?t understand properly is how calculate the oversampling value to get the data, I mean the baud rate. I?m working with the digilent?s code rs232RefComp.vhd (
hello, I want to make rs232 serial interface of fpga with pc. i need a vhdl code for this. also i want to know how to assign the pins in the fpga for this? I am using xillinx spartan 3 kit. thank you.
Hi everyone! I am very new in vhdl and I need some help with the asignment I have to do. I want to send a character with hyper terminal to Spartan 3E board via rs232 and show its ASCII code on 8 LEDs. I have already implemented UART Receiver but now I don't know what else should I do. Do I have to make a new FSM to turn on the LEDs (...)
Hi all, I need to implement an uart module written in vhdl to comunicate with another module, I have tried to use this code (source) with this main: library ieee; use ieee.std_logic_1164.all; use
Hello, I am using my FPGA(virtex-6) kit for the project, project is rs232 to Ethernet converter, 1) i ll write a code for the rs232/434 and dump my code in FPGA then i need to transfer the data by Ethernet to other device or PC. 2) vice versa the data which is coming from the PC or device from the ethernet port need (...)
We are trying to do some homework making a rs232 transmitter... This is what we made so far and there is a lot of faults it it.. but we don't know what. We think its something with the way we written the states. Please rewrite it to some useful syntax this is what we made so far library IEEE; use IEEE.STD_LOGIC_1164.ALL; us
hello everyone, i had written uart receiver module and baud generator module for baudrate:9600 bps in vhdl. This code is working properly for all 1 digit values. Now i want to send a text file containing datas such as eg: 123 56 234 175 34 100 how do i send this through rs232 to fpga??? Thank you all in (...)
I want to check status of DIP switch conecting rs 232(DCE) in xilinx edk 11.1, what will be my source code? pls help
Hi, here is a good thread for it.. rs232 vhdl-core | Comp.Arch.FPGA | maybe interesting.. i used it to do a part of my own UART
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
Hello, I assign both outputs and inputs of my uart vhdl codes to the 9 pins of that correct?? In the entity part of the uart vhdl code below, rx_data_out and tx_data_in are 8 bits width.I don't know how to assign them with the pin of rs232..anyone can help me?? entity uart_serial is port( -- (...)
I have a Xilinx Spartan-3E and what i want to do is this: Press a button ex. East Button on the board and send a signal eg. "00101100" to a device on the other end of Spartans rs232 port. Like when i press the button and the leds are on i want to send this signal over the serial port lets say to a PC on the other end. The only thing i have
refer rs232 in get verilog source code there
Hello! I am doing my final project in computer engineering and I need to connect a CMU cam into Ethernet. I was thinking of building a hardware using vhdl which will transfer between the Camera's serial port to Ethernet (and the opposite of course). Does anyone know where I could find such code? Thanks! Lior.
I am in need of source code of vhdl OF -- PS/2 and rs232 --Protocal!! if you have it ,or you know how to program it in vhdl , please help me!:| thank you very much!:D
i have spartan3 fpga starter kit from xillinx i want vhdl or verilog code to interface with ps/2 and serial (rs232) thanks for any help
Would anyone share the rs232 vhdl code ? If you have rs232 test program , please share. Thanks a lot.
