Folder Hierarchy for NXT Brick?

Folder Hierarchy for NXT Brick?

Postby katherine97 » 06 Mar 2012, 23:48

I was wondering if anyone knew of a diagram that exists which shows the file/folder structure on the NXT brick that you control using the buttons on the brick. I'm looking for a document that will show the folders and sub-folders that are displayed on the brick. Does anyone know of anything like this, so I don't have to create it myself?

Thanks

There is no folder structure on the brick. The "folders" you see exist in the firmware only. The "Try Me" folder is really just a list of files that end with .trm (IIRC). The programs is a list of programs ending in .rxe. The sounds end in .rso. So the structure you see is just the firmware presenting the flat contents in a nicer way.

I'd like to add, that any file not using an NXT specific extension will not show up in the FW menus. For example, you can use .txt files in your programs, but they won't show up in any FW menu.

Thanks for the replies. I guess I didn't explain well enough what I was looking for. I'm trying to find a diagram that lists all the options on the brick when you turn it on and scroll to the left or right: My files, NXT Program, NXT datalog, View, Bluetooth, etc. And then it lists what are sub-options of those categories, like in My Files it has: Software files, NXT files, and Sound files. I think I'm just going to create my own diagram because I'm only looking to highlight a few of the categories on the brick.

Thanks again.

IIRC, something like that is included in the paper-work that comes with the retail NXT sets (at least the 1.0 set).

With the 2.0 set, the only one that has anything like a complete list of functions is Bluetooth. All the others give you a hint, then you are on your own. They apparently assume "any 10 year old can figure this out".

Googling "nxt menu system outline" gave me this link. It might have the information you are looking for on pages 21 and 22.

John, that's a good starting point for 2.0. Here are things in my 2.0 brick that are different from that diagram:
1) "My Files" includes "Datalog files".
2) In the main menu (top line of the diagram), after "NXT files" is "NXT Datalog" with a submenu similar to "View".
3) In the "Settings" menu, "NXT version" is between "Sleep" and "Delete". This gives: FW NBC/NXC, AVR, BC4, BUILD, and ID.

The values my brick shows for the NXT version are:
FW NBC/NXC 1.32
AVR 1.01
BC4 1.01
BUILD 1402122005
ID 00165300D33B

Does the "BUILD" correlate to anything we see with your FW builds? Or is this something else? Methinks I have your latest FW installed.

Thank you so much for this; it's really helpful. I guess I didn't know what to call what I was looking for, so I had a hard time searching for it. I work for a nonprofit that partners with public schools to help them enhance their STEM curricula, so part of my job is teaching teachers how to use NXT kits in their classroom. I think having a visual reference of the menu for the teachers and students will be useful.

Thanks again!
