USB support for Ndless
« on: March 31, 2012, 02:46:43 pm »
Today, ExtendeD reports on his blog he managed to make USB work on Ndless. Support is rather instable and preliminary right now, but his demo program, which only requires a few lines of code, shows the name of the USB device plugged in.



Obviously, this opens new doors to Nspire development, as you can write programs that uses USB devices, such as flash drives, mice, keyboards, name it. You have to write your own driver though, but porting existing BSD drivers should be possible as the TI-Nspire OS USB stack is a modified version of the BSD one.

So this works with Fat32 drives, judging by the 4gig size?  Cool :D

Any USB host works with FAT32 drives if a FAT32 driver is written for it (and currently there are no USB drivers for Ndless :P)

I didn't think this would be accomplished within the next few years, considering how long it took on the 84+ for some people to handle USB programming O.O

Yeah, that is what I thought. I am glad for this, especially for when I get my hands on an Nspire...

When you'll receive the CX CAS you won at the zContest :P

Also, this is great news :D
The CX already had a lot of memory, now I see mine with a 500 GB external hard drive on it :P

Usually Hard Disk Drive, and Solid State Drive :)

Indeed. A host-capable controller, such as the ones in the 84+(SE), the 89T and the Nspire, ought to be able to drive a hub (externally powered), and therefore multiple Human Interaction Devices connected to the hub.

Wow!
Once again, the Ndless team amazes us!

I'm not sure that the USB key is useful since the Nspire has a huge flash memory...
But it could be used as a very convenient way to send documents to the handheld.

this opens the possibility of making the emulator of bigger games (SNES?) :D
Great job, people! XD

I do believe in this :D this is another point in history! How easy can it be to use BSD drivers without changes?

It's currently not yet possible, but it hopefully will. The most difficult part is to extract all the dependencies of the driver (for example mass storage also requires SCSI, FAT32, ...)
