DS development > Natriums new PassMe? (nope, a microcontroller)

#70600 - lockwood - Tue Feb 07, 2006 5:55 pm

Quote:
From the topic in #dshwdev on efnet, Natrium42 has been busy working on the next best device for the DS. This one includes USB, Serial, 18 I/O lines, a tilt sensor, and will be reprogrammable by the DS. I'm sure a slimmed down version that will fit into the DS slot without all the extra features wouldn't be far behind.

Check out the 3D drawing

Can natrium 42 say something to this?

questions about the hardware:

what are 18I/0 lines?
what kind of usb?

#70603 - Xgame - Tue Feb 07, 2006 6:19 pm

mmm, in natirum 42 blog there isn' t any news; but serial interface si an old news(http://natrium42.com/projects/serial.html)

#70620 - natrium42 - Tue Feb 07, 2006 8:45 pm

It's not a PassMe! :P

seems a bit overkillish...

But I want a GBA linkup port & hack one day so I can play Four Swords on the GC again ;)

#70673 - HyperHacker - Wed Feb 08, 2006 4:09 am

Is this a client or host USB port? Either would be awesome of course. (Actually I bet you could use either as either with a modified cable.)

Sounds pretty sweet though. Just needs to throw in a GPS reciever. ;-)

#70680 - natrium42 - Wed Feb 08, 2006 5:06 am

It's USB client. I have looked into USB host, but I don't really see a point since power would be a problem.

GPS module can be connected, of course :)

Mainly, this will be an improvement on my first serial hack with many extra features. The first serial hack was a bit unreliable in the PC->DS direction, and sending/receiving blocked ARM7 CPU. DSerial uses a microcontroller (connected to SPI lines of DS -- EEPROM port) to handle all I/O communications. This should be very reliable and flexible, because the microcontroller can be reprogrammed from the DS.

Most people would use DSerial as a debugging cable, but it can also be used for interesting electronics projects. Some ideas are:
1. Servo motor controller
2. Proper GPS, of course :)
3. Ethernet
4. Infrared remote (TV / IR toy cars / ...)
5. Additional LCDs ;P

There will be also an optional tilt sensor that could be used for interesting games, like a Marble Madness clone.

(I also wanted to add, that the pin headers will not be populated, unless requested.)

Maybe somebody else has some good project ideas?

I second camera O_o

Allthough I am more interested to see how far the DS can go as an Augmented Reality device.

For instance, could it be programed to recognise simple shapes?
I have an idea to one day make a AR "tag" game where everyone needs to wear special tshirts :p

The DS is probably not powerfull enough to use the camera as a gyro though. (clever techique the Gizmondo use's, allthough thanks to management fuck ups, people wont ever see it)


===

Incidently, What would it take to make the DS work with the GC/GBA link cable?
I notice the GBAMP can load *.gba multiboot games already. (for instance, stuff that can only be played with the GC link).

#70738 - dualscreenman - Wed Feb 08, 2006 1:56 pm

Hey, if it could support ethernet, what's stopping somebody from making a wired web broswer. Hmm, I guess making ethernet support is just about as hard as creating wireless support. Oh well, just a dream. This device looks cool.

#70748 - Snowy? - Wed Feb 08, 2006 3:20 pm

I think it would be awesome if someone could build all this into a new bottom case for the DS... A DS with IR, USB and maybe even GPS built in (Ooo SD card slot).

If your worried about the Power why not mod the GBA port to accept a nice Battery pack addon while your at it... easy to change batteries in that wasted space.

I can but dream but I must say I do love natrium42's work :)

Maybe I should just get a PDA... Nah not as much fun

#70872 - HyperHacker - Thu Feb 09, 2006 6:05 am

That would be sweet. Just a thin attatchment that snaps onto the bottom. Could fit all sorts of things that way.

And USB hosting power wouldn't be a problem if it were plugged in. ;-)

#70893 - Mrshlee - Thu Feb 09, 2006 10:10 am

Think NeoFlash PSP 14in1 thing..
Have it plug into the GBA and DS slot..
Host a whole load of random features but would you want MORE bulk on the thing... I would if it came to functionality.

A MIDI in/out set would really rock.

DS is a synth controlled by an external sequencer.
or
DS is a MIDI controller like that Korg KAOSS pad doodad.
or
DS sends a midi clock signal and synchronizes like 16 nanoloops.

Now that is an idea that gets me excited!
Using the X/Y coords of the touch screen to control different midi parameters (all configurable via a nice submenu of course!). The buttons could be mapped to different midi note messages for control of samplers etc.
Using the DS itself as a synth is cool for novelty value but the shitty headphone out destroys any real world application.
Using the DS as a MIDI controller however is just plain cool!!
If no one gets round to doing this then I think I may have found my first HW mod project...


:theory

#71081 - FourScience - Fri Feb 10, 2006 7:05 am

This looks great. I've been wanting to strap my DS onto my robot for a long time now. I was going to mod my PassMe to accomplish some serial connection, but this would really facilitate things.

I wasn't even thinking I'd use the DS as any kind of controller (servos, sensors) but with this it might not be so hard to setup.

I think you should integrate two IR LEDs.

Support to connect USB webcamera and USB printer would be awesome. I hope those are not impossible.

An IR Sender/Reciever would be worth adding in

DEFINETLY put in the IR sender/reciever. It looks like USB is already on there correct? Bluetooth would be cool too, but i think its possible just to use a usb adapter for that, so that would just make it cost more, so no built in bluetooth.

IR sender and reciever would be kick @$!. I was just thinking of a camera with the OLD serial connector. This would be way better though....

Any thoughts on price? and whether or not u would release documentation or something so lynx could make it as well?

#71731 - swimgod - Tue Feb 14, 2006 3:45 am

how about another touch screen
:P
is that even possible?
make it thread the wire inbetween the two screens then right on top or the top screen

that would be really cool if you could make them both touch screens
expands the possiblilt's of gui's

see, one touch screen makes sense because you can control two at once
in games it requrires quick reactions some times so one touch screen

but what if you wanted to create a more interactive gui for your ds
you don't wanna be limited to one ds :P
i would rather use a touch screen then buttons :P

Apple II and classic Mac printers ran on the serial port. Nowadays, now that printing tends to be IP based, we could probably just wait for sgstair to finish TCP and then print stuff by connecting to a printer.

I mean, can't it put in the RSA signature just like it was done with WifiMe using hacked parts of super mario 64 ds or something?

#72298 - Mrshlee - Fri Feb 17, 2006 12:48 pm

I don't really find a point of adding a passme on it :S
Realtime Debug yes
T.V. remote yes
robosapian AI + wifi controller.. yes
NoPass waste of memory space

Arnt we going a bit overkill?

If we just have a standard interface slot (USB), and then an easy way to add stuff onto it manualy, isnt that enough?

That said, GBA link up slot please :p

I would rather see buildin IR or GPS, that would defenitely stimulate good app's (like you could send MP3's from DS to DS with MoonShell for example =P ).

I used to be able to live without a backlight...now I cant.

And I refuse to buy an SP/Micro when I already have a perfectly good GBA-playing device here :p

IR seems pointless, unless you think DStoDS homebrew will never be possible with Wi-Fi. (which, I dont, personaly).

GPS is way overkill.
If there was an ability to easily add it though...can you get USB plug-in GPS devices?
I do love augmented reality gameing ideas. (as well as wardriving uses)
But built in is hard/expensive.

#72538 - MrD - Sun Feb 19, 2006 5:59 pm

I want a module that converts the DS into the Digipad from Shadow of Memories / (of Destiny).

Actually, I tried to build that device today :)
I connected a LED directly to the audio line of my iPaq and was able to control a Toshiba DVD player. Sadly no other devices work that way, because the signal is too weak. The real Total Remote thingy uses a special 500Hz preamble at beginning of IR communication to charge up some internal capacitor that then drives an amplifier. But I suck at analog electronics, so no idea how to make one...

It would also depend on demand as well as price breaks for components, how many he has to order (risk) to get the discount, etc. And how he plans to sell them. Fully built, or will you be able to order one without the tilt sensor, etc.

Personally, you couldn't pay me enough to build them. I hate SMD components (CPLD, no problem, but resistors the thickness of your hair? Forget it!).. So, as everyone else, I can't wait to get a couple, just hope they aren't too expensive. :)

#73352 - quadomatic - Sat Feb 25, 2006 12:44 am

#73576 - HyperHacker - Sun Feb 26, 2006 8:20 pm

I think a camera would kick ass too, but that'd be a separate project. The GBA slot seems like a good place to put it; have it stick out like GBAMP and put the lens on the back.

#73596 - tepples - Sun Feb 26, 2006 9:27 pm

Put a Game Boy Camera in your GBA SP to see how that would turn out.

#73789 - tepples - Tue Feb 28, 2006 3:02 am

For one thing, the image would be upside-down. For another, it wouldn't be pointed along your line of sight, which is essential in a camera.

The only way a camera would really work on DS is if it plugged into the DS slot. Or if it were linked to the GBA option pak by a cable, and maybe clipped to the top of the DS.

Or.. why not just hold the DS on whatever side it would require you to hold it to take pictures, and just display the screens that same direction. Just like some games already released where you hold your DS sideways, holding it upside down seems just as comfortable to me as upside right.

#73843 - FourScience - Tue Feb 28, 2006 8:41 am

Images can be flipped very easily so don't worry about upside down orientations.

#74359 - natrium42 - Sat Mar 04, 2006 7:48 pm

I don't really see a point in a camera for DS, so maybe you can explain what you have in mind.

What would you rather buy: a $100 camera for DS with cellphone-cam-quality or a $100 decent consumer camera with good quality?

Oh, and also, I assembled two DSerials for testing and was able to control a LED with the MCU. The SiLabs in-circuit debugging is really neat. Going to continue to do more testing without DS, since DSerial can be stand-alone microcontroller board.

The thing about the DS is that it can do a lot more than the official developers out there are doing. No one is willing to push the bar because the publishers are afraid it may be a flop. They don't trust that people might actually want non-game applications on the Nintendo DS.

That's one thing I like about the DS. It's really turning into an every-day tool for me, since MoonShell was developed. Once web browsers are developed, and other awesome little doo-dads are put together, it will become a tool I won't want to be without for many things. Like a much-cheaper PDA it's pretty impressive in most cases. :) And the possibilities are still limitless.

I use a USB Debug Adapter. But yeah, it's also possible to make the final design reprogrammable via USB by writing a special loader.

You could buy a standalone camera, but then you have to carry both it and the DS. Having one right in the system would be far more convenient, and you could use the already-present CF/SD/flashcart to store the image, maybe send it right to your PC through nearby Wifi, or edit it right on the system.
Upside-down images isn't a problem, just mount the lens upside-down. Line of sight isn't a huge issue either; the display on the screen would show you what the image will look like just like any other digicam. If it's really necessary, the camera could be connected via a cord to the cartridge and attatch to the back of the system via a suction cup or clamp of some sort.

this is great now ill just wait and hope that a camera for the DS or a USB slot comes true

#74985 - quadomatic - Thu Mar 09, 2006 5:32 am

any more news?

any word on a release date also? since u got 50 pcbs....

#74991 - HyperHacker - Thu Mar 09, 2006 6:22 am

Maybe he should build a camera into it, just so people will stop asking for one. ;-)

#75031 - jester - Thu Mar 09, 2006 5:37 pm

yeah exactly thats precisely wat someone should make a camera add on!!

#75040 - quadomatic - Thu Mar 09, 2006 7:19 pm

NO DON'T PUT A CAMERA ON IT!!!!

That'll just make it cost more. If people want a camera, just go buy a pc camera and make a ds program for it and plug it into the USB slot (u can do that right?)

i agree, make it an optional add on ;)

No, as it is a USB Device port, not a USB host port.

the usb slot is ONLY for plugging it into USB Hosts. Generally, the only things that are USB Host, are your home computers.

#75091 - quadomatic - Fri Mar 10, 2006 1:58 am

maybe there is a usb host camera? id just really rather there wasn't a camera attatched cuz it would cost too much...

maybe usb to serial port?

BTW: I'm confused about wat an RS-232 serial connection is. I googled for some pictures, and the connectors all of 6 pins...but then how do those types of things connect to DSerial? I only see 3 pins on the DSerial above the USB connection..or does the USB connection unplug?

#75137 - jester - Fri Mar 10, 2006 12:58 pm

yeah thats true maybe natrium24 should make a USB port and a program for the DS to go with it so people can attach their camera's instead of buying new ones.

wouldnt that cause a lot of driver problems, or is there some sort of generic driver that could be used?

maybe it depends hopefully he can make a USB port though then it would create new levels for the DS homebrew community!!

You could connect the MCA-25 mobile camera from siemens that is cheap on ebay and has a serial interface. Informations can be found here (german): http://avr.auctionant.de/avr-ip-webcam/

I would use a powerful ARM7 microcontroller (LPC series) :-)

[edit] bah, you used an 8051... that's like placing a ford engine into a ferrari :P

Huh? In case you forgot, there is already a powerful ARM7 and ARM9 in the DS...no need really for another big cpu on the DSerial.

That's totally overkill for the task at hand. Using LPC would be like buying groceries with a Ferrari. Would only make the schematics/PCB more complicated and increase price. The C8051F320 fits just fine. It's a nice micro, actually, with built-in: crossbar, oscillator (24MHz CPU speed), full-speed USB device, USB resistors, 5V-to-3V regulator, temperature sensor, SPI, UART, I2C, in-circuit debug port. It only needs one external part: a 0.1uF decoupling capacitor. And when you are soldering by hand, even a small difference in component count matters. So I think, this micro is a perfect choice.
