VMusic2 - USB for the 83+

The TI-83+ lacks something the 84+ series has - a USB port.


Enter the VMusic2. This low-cost (GBP25) module offers a USB host controller with a simple serial interface that can be used to read/write FAT-formatted USB mass storage devices. It can also play MP3 files straight from the drive!



This is all very well, but the TI doesn't have a standard serial port either. To handle communications between the two, therefore, is a PICAXE-28X1 microcontroller.

The TI can then run a program that communicates using its standard linking protocol.


I've posted a thread on MaxCoderz with more information about the project. For those interested in the VMusic2 device, here's a datasheet and here are the commands.


1.48MB AVI (MPEG-4, MP3)

Yes, I know I should probably get a life. I blame the solder fumes.

You're a sick, sick man, Ben. [smile]

Are you gonna try HP calculators some time in the future? I want to get one of the new HP-49g+ or its brand new successor, the 50g.

Why, thank you. [grin]

The hp calcs are nice pieces of kit. I don't really use my calculator for that strange numbery thing (I think they call it 'maths'?) any more, so can't really justify shelling out on expensive calculators. I bought the VMusic2 not purely for its use in a silly TI mod, but it's a nice thing to have for other projects too.

This appears to be the music decoding chip - much more powerful than I had assumed! It supports a lot of formats.
