Using MIT Scratch Board / Picoboard w/ Processing?
Oct 24th, 2008, 4:12am  
Hi -

I've got a Scratch Board (now called the Picoboard) from MIT's excellent Scratch project, and I'd like to see if anybody has tried using it in conjunction with Processing.

If so, are there any tips/strategies you can share?

Here are some links:

I did a bit more poking around, and tried a few things.

First, here's the technical spec on the PicoBoard:

http://scratch.mit.edu/files/scratchboard/ScratchBoard_Tech_InfoR1.pdf

Unfortunately, I don't have enough experience with hardware integration for that document to be helpful. Here's what I also tried:

I opened up the SerialDuplex sketch by Tom Igoe (in the Serial library) and ran it. It showed the following serial ports:

Java lib Version   = RXTX-2.1-7
[0] "/dev/tty.usbserial"
[1] "/dev/cu.usbserial"
[2] "/dev/tty.PL2303-0000101D"
[3] "/dev/cu.PL2303-0000101D"
[4] "/dev/tty.Bluetooth-PDA-Sync"
[5] "/dev/cu.Bluetooth-PDA-Sync"
[6] "/dev/tty.Bluetooth-Modem"
[7] "/dev/cu.Bluetooth-Modem"

Now, I know from installing the Scratch board that it uses the PL2303 USB-to-serial driver, so I tried setting the sketch to use either port 2 or port 3, both of which are labeled "PL2303", but I'm still not seeing any sign of data showing up in the sketch.

I did test it out in Scratch, and verified that the board is sending data OK (it shows up in a Scratch program).

Any further thoughts?

Thanks in advance,

Bill
