USB Gecko C# example

[Nuke]

Hi,

for those who code in C# here is a USB Gecko code example project i coded, this shows how to use the ftdi chip in C#

It was my first ever program written in C#, so go easy on me :)

love the language though and think its great for GUI stuff.

project was made/compiled in visual studio 2005, but should import to any version higher

It worked fine in my Visual Studio C# 2008 Ed.
The program looks really nice :D
Does it work yet? My guess would be in the Gecko menu?

I started learning C# awhile ago, I also really like it for GUI, I haven't been able to program for awhile though :mad:

I was thinking some time ago.. I did learn C# some time ago. WiiRd uses one communication library to communicate with the USB Gecko. This library does everything (usbgecko.pas) - I guess I could port this to C# if there is interest though!

I'm interested!

So well.. I finally had some time to recheck the code.. well, C# progress is fine.. I implemented the core functions and already one user function.. which is a complicated one: the dump!

right now its syntax would be:

Code Select Expand


public void Dump(UInt32 startdump,UInt32 enddump, Stream saveStream) { }

So a basic call would be Dump(0x80000000,0x80400000,fileToSaveTo);


The reason I went for dump is simple. It is a quite complicated, yet absolutely important function. It has the strongest communication part with the Wii console:

• Reset buffers
• Announce dump command (send 1 byte 04 to the USB Gecko)
• Wait for the reply (should be 1 byte - and AA = Acknowledge)
• Send the memory range to dump in Big Endian to the console: a valid message would be 80 00 00 00 80 40 00 00 = dump from 80000000 to 80400000)
• wait for ackowledge
• Now packages are split.. package size of each max package is 63488 bytes (3968 for upload). So the download has to be splitted into packages of maximally 63488 bytes
• Get a package
• Check its length - if invalid: retry the package (send BB = retry to console) - after 3 retries give up (send FF to abort dumping)
• if invalid transfer status reply: give up (Send FF)
• if length okay and no status error: ackowledge package: send AA
• Next package or finish if all packages done

So well.. that's the truth behind the dump command for those who didn't know it.. and well..that command being a core command is working. If anyone wants to get a glance at the current communication library with the dump example. Sure!

The biggest thing i'd like to see is the debugger improved, rewrote to C#.

How about i come up with some bounty source thing, so we can make this happen and i fund it?

I want to try pick up USB Gecko, and i think the only way i can do this, is either hire coders so i can focus on support or do it as a collaboration community thing and i fund it.

i'm open to suggestions.

[Nuke]

made a start on this now.

Nice one!

[Nuke]

btw Link if you finished that function, i'd be happy to put it on the new site as an example of using C# with USB Gecko.

Sure, I'll get the code asap (when I am at home)

[Nuke]

thanks buddy.

Contains dump function.. I hope I'll get around porting more functions but for now that's it!
