Would anyone share the rs232 vhdl code ? If you have rs232 test program , please share. Thanks a lot.
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 know.here 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
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
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
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( -- Global signal areset
Does anyone have uart example of vhdl where i can test my rs232 on my board altium?
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
Doing Complete calculator in vhdl wont turn out to be economical design. What you can do is you need to write / use some 8 bit vhdl CPU to do the job. Using this cpu you can interface keyboard and display to it. And use it for doing calculations also. 8051 core in vhdl is available you can use it. For testing you can use (...)
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
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.
refer rs232 in www.fpga4fun.com....and get verilog source code there
hi , i didn2t want to open a new topic for this, thats way i write here, could you tell me which rs232(i think there are rs232 on different voltages) should i choose for FPGA, i also will implement uart. thanks
This is really getting nowhere. Do you know ANYTHING about USB or FPGA at all? First of all, Using USB to communicate between an FPGA and a PC is like trying to fly a 747 in order to go to your friends home next door. USB is complicated, difficult and complex protocol and in NO WAY it is communicating in ASCII, unless you have a special devic
you could create a memory with the values of the text file, generate it through IP wizard and read it. Every time that you want to read a image you have to modify your memory and recompile the entire project. This is like and "offline" solution. Or, if you want to read "online" the text file, you could send the values through serial (rs232) cone
hi all, i need for a project to decode characters sent to rs232 Receiver module the RS 232 receiver will feed its data to the LCD display and that will be on spartan 3A . i have the rs232 Receiver module done but what i am missing is the part related to the LCD display as i want one and i hope it is in vhdl and not relying on (...)
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 advance..........
Please look at opencores.org. They have rs232 as well as ethernet mac core.
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 to be stored in the rs23
some issues are apparent: 1.) rs232 is lsb first, so "z" will come up as 0 0101 1110 1. 2.) you appear to transmit "M" lsb first (correct), but the start/stop bits are swapped (incorrect). eg, x1(0) = '1' and x1(9) = '0'. Thus the framing will be incorrect. the receiver may see 11001001 as the data byte, which would be an extended ascii charac
I have a problem with rs232 transmission. It doesn't work even when i send the first, start frame($55). Next frame $3x choses a led and the last one turns it on/off. I cant even turn on a led when i get start frame. I cant find any mistakes in a code. Maybe You will find something or give some advice. I enclose code with a problematic part. [COD

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
there appear to be a total of 64 elements in a small implementation and 4096 elements in the large implementation. What specifically are you expecting the vhdl to do? for example, is this a simulation only construct? is this a synthesizable construct? how do you plan to put data into the structure? eg, data from a PC (ethernet/usb/rs232 interfa
My favorite example for rs232: The code used in that article is verilog, but a lot of useful hints in there that you can use directly in your vhdl design.
I am not familiar with ASIC design flow, maybe somebody else can give some valuable comments.... For FPGA design, what I have used synthesis tools(only to synthesis vhdl code): Synplicity Synplify > Synopsys FPGA Compiler II > Mentor Leonardo Exemplar It is only my personal opinion...
Hi friends, I need to connect two PIC using USART, but considering the long distance, I think I'll need to convert rs232 to rs485 and then back to rs 232. Does someone has suggestions, esperience about the solutions I should use ? thx proton

I am a student from Harbin China. Now I am building a behavioral model of a Direct Sequence Spread Spectrum Communication system using vhdl-AMS. So i want to know where can I find some example similar to that or something that may give help to me. Can you give me some advices. Thank you! [ This Message was edited by: flybear on

Please suggest good books in this thread for vhdl/Verilog ASIC design Thanks,
Hi Piccy, The R4 are for current limiting, protecting in some way the PC rs232. Because of the high impedance of both input the current carried by the GND is little, so you don't need high power resistor. Instead of 0.1 uF you can use 1uF in m@x232, I have already tried and everything works fine. Hope helps, NeuralC
