Modulation Techniques with FPGA and Matlab

interfacing fpga and serial port with matlab

Hello,
I have a project that relate to FPGA and Matlab.
In this project, i must use Kit UP1 of Alter as a modulation circuit.
The main idea of this project is :
Using Matlab to interface with UP1 via Serial Port.
Matlab will send modulating signal to UP1 Kit
UP1 Kit will process as a modulation block with modulation schemes (AM,FM,ASK, FSK..)
And then, send the modulated signal back to the Matlab.
There are too many problem need to solve so i need your help to do it.
If you have any suggest. or documents about this, please help me.
Best regards,

Matlab can read serial port
use serial command

but before that you have to open the port and also choose COM ports according to the configuration of your PC.
then close the port.

Tell me the areas of problem then I can help you in a better manner.

Regards

Robin

Hi,
I've found some info about serial communication between PC and FPGA kits at here
https://www.fpga4fun.com
But i don't have many experiences with hardware prototype.
So could you show me the circuit for this connection via serial port between PC and UP1 kit.
Regards,

fpga and matlab

which port are u planning to use or which one does ur board support?
ps or db-9 connector or usb. make sure the availabilty of the ports and then proceed.
i think serial communication should not be a problem once u have ur configuration parameters set right.

cheers

I've build the circuit to test the program at
https://www.fpga4fun.com/SerialInterface.html
This program worked with Hyper Terminal, but i have problem when using with Matlab.
I write a model for sending data from port1 to fpga kit and then fpga kit resend data to port2. But it didn't work.
Can you help me to solve this problem?
I think maybe the delay beetween fpga and pc can be the reason.
And how i can send and received data on two port (or 1 port) at the same time with Matlab?
