Just a few bits of useful information if you're interested in running Arduino code on the CUI32Stem:

- use MPIDE to compile and send the code : http://www.chipkit.org/wiki/index.php?title=MPIDE_Installation

- hold down the "PROG" pushbutton on the CUI32Stem while pushing "RESET", this will put it into bootloader mode (you'll see a special pattern of flashes…

If you have one of these Grove I2C accelerometers from SeeedStudio, this example code will work with it.

Let's say you have 3 CUI32Stem boards, each with a ZigFlea board attached.  One of them is the 'base' and is attached to your USB port, while the other two have Grove I2C touch sensors attached:…

This is a fun little project done by some fine folks at CIID. Here's a bit of code to accomplish the same in StickOS:

If you would like to play simple major scales using a piezo buzzer or headphones / amplified speaker, the BASIC code by Rich Testardi below will do this.  

You can alter the rhythm by changing the amounts in the sleep periods, or change the scale by moving the whole and half-steps…

If you have one of these Grove I2C Motor Driver boards from SeeedStudio, then the following code may be useful...  Note also, that you'll need to add pull-up resistors to the I2C clock and data lines (say 10k ohms to 3.3v), since they're not included on the Grove H-bridge Motor Driver board.

A system for Do-It-Yourself (DIY) interfaces for Sound and Music Computing using the new CUI32Stem has been described in the paper below. The system is based on the GROVE system of interchangeable transducers. Together, the CUI32Stem and Grove provide a malleable and fluid prototyping process of ‘Sketching in Hardware’ for both music and non-music interaction design ideas.

The CUI32Stem is designed specifically to work hand- in-hand with the GROVE elements…

Just a public service announcement here: In order to offset the cost of the Ning service (the host of this webpage), Google Adsense is now enabled - hopefully they won't be too annoying!

I've documented some examples of using fairly inexpensive addons for the CUI32 that enable Bluetooth, Wifi (802.11), and ZigFlea wireless connectivity in the attached PDF.  Hope someone finds it useful!…

Hi,

I made a SID-shield for my custom CUI32 board.  It contains a SID 8580R5 sound chip from a Commodore C64, an OLED display and a few buttons and switches for user input.  Schematics, firmware, and some pictures of the project are available here:…

Hi,

the Maximite (http://geoffg.net/maximite.html) is another PIC32 board, which can be programmed in BASIC.  Its BASIC has even floating point numbers, and pixel-draw commands to draw graphics on a connected VGA or composite display.

Dear all,

I would like to provide external battery power to the CUI32.

My PCB underside says "3.5-10V" at the battery connector (by the way, on the PCB photo on sparkfun it seems the PCB says "3.5 to 5.5V !??) but from the schematic it is not clear to me if I can directly connect a 9V battery (for example). To me it looks like this would put 9V on the 3.3V DC/DC input (which would be OK) but as this is normally 5V (when USB powered) it seems I would get 9V on the USB pins and…
