FPGA

[Algoet]

Dear all,

I'm using Labview FPGA with the spartan 3E board.

I'm started with the LCD example.

Ascii texts no problem, but now I want to place integer values on the LCD.

So, I need to convert integer to a ascii format to display. ( array )

There is no function available on FPGA level, to write an integer to an array of bytes, in display format of course.

So, I'm looking for using a FPGA code block.

Some FPGA libraries have functions to write a integer to an output.

My problem : I have a full labview example to place text on the spartan LCD but no solution for converting my integers to ascii.

Passing through the FPGA code block, then I have to move full LCD control to FPGA code. But way using labview then.

Can somebody help me?

A direct function is available.Hope it supports

Picture got screwed up.

Algoet,

This is a very interesting FPGA problem.  To implenet this in FPGA, you can use something like the implementation of the "itoa" function in C.  Wikipedia gives the original K&R implementation.  It is not too hard to follow, and I believe FPGA supports all functions required to build the byte array of characters.  I might try to put this together myself just for fun.

On another topic, as an FPGA developer, are you aware of NI's IPNet for FPGA?  If not, check it out - lots of good tidbits.
