Yes, we now have 1000 digitizers! How many do you want? Where do you live?
2  Screen Tablet malarky / Heyaaaalpppp / Saving Wacom Digitizer Data using Microcontroller on: February 11, 2013, 05:50:58 PM
First off, thank you all for the amazing resource of information on this forum.

I am looking to build a drawing device that would allow me to capture and save my drawings without the need to be plugged into a computer. I am currently using a SU-13W02E-03A digitizer from ebay and I have built a usb cable adapter that works on my Windows 8 laptop.

I would like to use a microcontroller such as an Arduino or Teensy to capture the data from the digitizer and save it to an SD card. I would then make a program on Windows that would play back this data and could create a vector graphic.

My questions are the following:
- Is this feasible?
- Is an Arduino the correct device to use?
- Should I capture data from Serial or USB?

Thanks for the help!

Hey, I stumbled across this thread while researching the same digitizing unit (SU-13W02E-03A).
I would like to be able to connect this digitizer over USB to a Laptop and have it recognize a pen. I have 3 digitizers and 2 of the cables mentioned above. Based on what I've gathered here, I have tried to make a USB cable using a 3.3V regulator and connected the pins in the following order:

pin 1 - ground
pin 3 - USB D+
pin 4 - USB D-
pin 13 - 3.3V from regulator (5v in from USB)
pin 15 - ground

Is this correct? When I plugged it into my Windows 8 laptop, it was recognized as a pointing device. When plugged into a Windows 7 device, it installed drivers. This leads me to believe everything is working. So the next step is the pen...

As far as I can understand, there are a range of pens that work with this digitizer, but the ones for the new Wacom boards (Bamboo Intuos etc) do not work due to changes in the frequency used to communicate. That means that the intuos 1 or UD pens work?

Thanks for the help, sorry to restate a bunch of information. I'm trying to sort everything out
