Ayuda pure data+arduino

Hola, he estado intentando conectar la arduino con pd, pero tengo los siguentes errores:

mapping/tolist ... couldn't create flatspace: can't load library in C:/arduino-0005/pd blahsymbol: flatspace Opened serial line device COM4

** ERROR ** could not reset params to DCB of device COM4

** ERROR ** could not open device COM2: failure(0): No error

WriteFile failed, but isn't delayed on serialdevice Write error, maybe TX-OVERRUNS on serial line WriteFile failed, but isn't delayed on serialdevice Write error, maybe TX-OVERRUNS on serial line WriteFile failed, but isn't delayed on serialdevice Write error, maybe TX-OVERRUNS on serial line WriteFile failed, but isn't delayed on serialdevice Write error, maybe TX-OVERRUNS on serial line

¿ Alguien me podria sugirir algo? trabajo con windows.

Hola,

primero de todo:

1) Que version de Arduino empleas? La ultima es la 0008

2) Que version de PD empleas? Te recomiendo la 39.2-rc5, las posteriores aun no funcionan bien y las anteriores no incluyen el objeto comport perfectamente compilado (busca la ultima version en http://autobuild.puredata.info

3) Usas Firmata para comunicar entre PD y Arduino o solo lo haces por comunicacion simple enviando Bytes?
