Converting Wacom UD-1212-R from Serial to USB

[bernard]

UD-1218-R and UD-1212-R are (almost) the same device. Control board is the same (or at least I didn't see a difference) so the conversion guides will work as is. The difference is in the firmware to handle the bigger board and as a consequence the Waxbee configuration.

I just don't know if this thread is still alive, but I recently modified my old UD1212 serial to intuos2 USB emu based on this thread, although I have a trouble to make intuos2 driver recognize the original stylus pen. I am afraid I need an intuos2 compatible pen instead of the original. The tablet and functions are recognized well and status LED responses with the original pen.

OS is windows10, just for your info. At least, there are reports on the web that the intuos2 driver works on windows10, such that I speculate this is not due to driver issue. The driver I am using is 6.2.0w5.

Because of this trouble, I tried intuos5 emulation, but ended up with no recognition of the tablet at all, by the way.

I appreciate your kind help.

Thanks,
momo

The driver not seeing the pen can be a sign that the tablet is not communicating with the Teensy/Waxbee.

The driver could be seemingly functioning even with only the Teensy unit connected to the computer without the tablet. And the pen still can interact with the tablet's LED even though it's not connected to anything.

You don't need a newer pen if the one you've is still good. I would try checking the soldering job.

Hello DD,
I will check my solder again.
Thank you for your clarification and advice.

Hello Everybody,

A little bit lost in my deep french countryside, I am trying to convert my old serial UD 1212 r Wacom into an usb one.
Many thanks to Bernard, Red five, DOCa Cola and all the contributors for their explanations, who are very usefull.
I just want to ask two questions:
1. Is it possible to make that transformation using an Arduino pro-micro Teensy 2.0 compatible device as this one:
 http://www.ebay.es/itm/ARDUINO-PRO-MICRO-5V-16M-COMPATIBLE-ATMEGA-32U4-MICROCONTROLLER-BOARD-TEENSY-2-0-
2. May I use my old wacom pen or is it absolutely necessary to buy an Axiotron Studio Pen?

Best regards,

Christophe

1. Pro micro and clones are incompatible with Teensya 2.0 There are two problems: pinout (different pin names, not big deal) and bootloader (arduino bootloader suck). Rest (uC, crystal, USB section) are almost identical.
I tried to program old WaxBee into pro micro. With success. But I need external programmer to do that. More info here: http://forum.bongofish.co.uk/index.php?topic=2556.0
Newer WaxBee version have smaller size thus You can use arduino bootloader that are inside pro micro. Just programming process are different. WaxBee can program teensy or generate hex file. You need manually call AvrDude with specific parameters. That's probably the most important difference.

2. You need working EMR pen. Original Wacom pen will be excellent as long as it working (moisture and time may destroy everything). Replacement pen may working too but I never played with that.

Thank you for your prompt answer Ertew, I will try it and I will give a feedback on this ASAP

Sorry for late response. All my old pens still work. Often when one doesn't work it's because it needs "tuning". For wacom pens typically it is 2 little screws inside the pen. You must turn only one at a time and return it to precise position. If you turn both a lot it will be very difficult to find the working positions. (take a detailled closeup in-focus picture for reference). The hard part is opening the pen without breaking it. (lookup this before attempting).
