Sony HDR-HC7E video tranfer

syyang85 — Sun, 03 May 2009 18:25:43 +0800

Hi, I've Sony HDR-HC7E video cam.

I forgot I bring my I-link cable which is provided with the package.

I went to the store to look for I-link cable, but salesman told me that they no longer sell i-link.

Instead he offered me a sony usb cable which cost rm99.

I declined the offer since he said that it's a standard usb cable.

So, back home. I tried connecting my video cam with my computer using those external harddisk usb cable.

But the video cam couldn't be detected.

any helpful info?

SVG access

syyang85 — Fri, 05 Dec 2008 17:45:29 +0800

I have some questions.

My svg file is embedded in html file, A. Another html, B, shows the previous html file A in iframe. The thing is, how do i gain access to the svg?

It's like this <html><iframe><html><embed>SVG</embed></html></iframe></html>

i tried svgdoc = document.getElementById('flowerframe').document.getElementById('flowerprop')getSVGDocument();

and

svgdoc = document.getElementById('flowerframe').embeds('flowerprop')getSVGDocument();

but with no avail.

flowerframe is the id of the iframe which sources the other html file.
flowerprop is the id of the embed which sources the svg file.

How do i fix this?

VHDL loop error

syyang85 — Fri, 21 Mar 2008 20:44:49 +0800

This is a typical counter which counts until 31 with every clock coming in
but im havin this error

QUOTE

Error (10398): VHDL Process Statement error at count31.vhd(27): Process Statement must contain only one Wait Statement

why can't i have more than more than 1 wait statement in the process, if not how am i ever to loop it?
any ideas?

QUOTE

library IEEE;
use IEEE.STD_LOGIC_1164.all;
use IEEE.STD_LOGIC_ARITH.all;
use IEEE.STD_LOGIC_UNSIGNED.all;

entity COUNT31 is

port ( CLK: in std_logic;

COUNT: out integer);

end COUNT31;

architecture behav_COUNT of COUNT31 is

begin

P_COUNT: process

variable intern_value: integer;

begin

intern_value:=0;
while (intern_value<31) loop

wait until CLK='1';
intern_value:=intern_value + 1;
COUNT <= intern_value;

end loop;

end process P_COUNT;

end behav_COUNT;

when i try to change wait until CLK='1'; to if (CLK'event and CLK='1') then

It gave me warning of exceeding 10,000 iteration.

Why it wont exit the loop when the condition of (intern_value<31) is fulfilled?

savin data in SDR SDRAM

syyang85 — Fri, 14 Mar 2008 10:13:17 +0800

I building a project that suppose to grab image pixel data 50x50 and save them into a SDR RAM.

i've build a component that extract 50x50 from the full resolution. but now i need to save the 50x50 into memory.

guys, do you know what is the best way to work around with this?

I didnt saw any megacore ip for this SDR SDRAM but i did found that there's a sdram controller in sopc builder.

As, I'm quite new to this. I would like to know what is avalon in sopc builder, and what actually sopc builder do?

I followed the instructions for building a nios system. but how does this system actually helps me in saving the array of data in SDRAM?

What i know is that we can run C program in a nios ii system. but i do not need to run a c program for this system.

send data thru Serial port

syyang85 — Fri, 18 Jan 2008 04:49:56 +0800

I captured some image using matlab thur webcam and i need to send them to another device via serial port.

I'm still new to this matlab. so i was thinking how can that be done. Usually, what can of approach do they use?

My image is in 50x50 array.

Do i need to change my image from matrix form to string format?

how do i fwrite that into serial object port?

Frame Grabber using FPGA thru webcam

syyang85 — Mon, 17 Dec 2007 22:05:45 +0800

Hello,

I'm a student doing a project on implementing optical flow algorithm into FPGA.
Basically, i would like to mount a camera ( preferably webcam coz its cheap) onto a FPGA( my college currently has up2 and up3 @ltera education board) and it do some image/video processing in FPGA and display in an LCD or CRT monitor.

As for my part, I'm doing the input part. That is getting the data(image frames) ready for calculation in the FPGA. the Frame Grabber should grab image frames from the camera and converts it into gray-scale and saves it in Matrix form or what ever meaningful form. It's quite a challenging project Very Happy so, I need all the advise/help that all I can get.

From what I read throughout the forum. Is true that is the least practical to use a USB device on FPGA? The up3 board that I'm using has USB port, so I was thinking of just using my cheap webcam that I've already own. What do I need to prepare if I decide to use the USB webcam? I found out that there's a USB port in up3 board and there is ip-core on USB in opencore.org. What other better alternatives do you guys suggest? and what other advises would give regarding my project on the Frame grabber.

Thank you for your precious time on reading this.

Regards,

Sim

VHDL and MATLAB

does anyone has experience in fpga, vhdl and matlab?

i have some questions to ask

How does a webcam transmit data/signal?

syyang85 — Thu, 11 Oct 2007 21:06:13 +0800

After asking around, i was told that. webcam is nothing more than a digital camera. The 'webcam' function is actually done by computer.

so, is it true that when the camera captures a frame its actually send each color data of each pixel to the computer via usb until it forms a picture in the computer? If, so what is the sequence of sending each pixel? meaning to say top to bottom or left to right or zig zag?

Thank you.

Well, my cmoy isn't working. dunno what's wrong. followed the tutorial in tangent, no mods or whatsoever.

So, is it correct?
