VMusic2 - USB for the 83+
Monday, 21st May 2007
The TI-83+ lacks something the 84+ series has - a USB port.
Enter the VMusic2. This low-cost (£25) 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.
Yes, I know I should probably get a life. I blame the solder fumes.
