how to given inputs and outputs to the fpga

[nithin.j38]

hi
i want know how to given inputs and outputs to the fpga
i am doing project 16 bit multiplication
so i got output 32 bit
but in the fpga kit there is only 8 leds for the output declaration
how can i give outputs to the fpga

You should be able to use the other unused I/O pins and wire more LEDs.

You may use graphical LCD interface to show your results..
If not experienced before, it can be little bit difficult, but
if you do it once, you can use it forever.

+1 to the idea of Ilgaz..
or you can store the result of the multiplication.. transmit via serial port to an Hyperterminal and see it in a computer's screen...

what kind of fpga do you have?

 

[nithin.j38]

i have spartan 3e kit

Thanks mersault...
Your idea is also nice.. However, For newbies it may be more challenging. If nithin.j38 uses spartan3, the easiest one is 7-segment display... What you think?

how can i see output using the lcd
please explain to me

On the FPGAs, there is an lcd driver IC. You should find the datasheet of IC, and read it..
For driving the LCD, you do not directly drºve the LCD pins. You drive LCD driver IC according the timing specs.
You can easily find LCD driver codes for any type of FPGA LCD driver IC..
Try to find them at opencores.org

It's O.K. to discuss about the LCD output option. However, can we expect as the next question "How do I enter the input data
with only 4 switches on by Spartan 3-E board?"

The obvious problem is, that your "project" is either specified incompletely or you didn't tell it. It's like building a house and
asking about the windows later on.

FvM is right..
We are just talking about to show outputs..
I have some ideas for giving inputs, but not a good idea as well...
You can use switches and each switch config represent input data.
But you cannot use your code as a module..
You can't give any other inputs, you need to change the code and implement the whole project again..
Look at UART!!

how can i use lcd display in spartan 3e
for these one is there any data sheet
if u have please send to me

On Spratan3e, there is Sitronix LCD driver IC...
Look at this link, this is exactly what you need...

How can we transfer data from fpga to pc through hyperterminal??? Must it be serial or can it be parallel??

What do you mean that you can't use your code as a module...??
