got TextEdit.app to write '.pdrc' file wit the instructions:

placed it in Users/Home/ directory and open PD afterwards, I got:

reading startup file: /Users/tiagoborgesdasilva/.pdrc

GEM: Graphics Environment for Multimedia

GEM: ver: 0.888-pre1

GEM: compiled: Jan 28 2004

GEM: maintained by IOhannes m zmoelnig

GEM: Authors :  Mark Danks (original version on irix/windows)

GEM:            Chris Clepper (macOS-X)

GEM:            Daniel Heckenberg (windows)

GEM:            James Tittle (macOS-X)

GEM:            IOhannes m zmoelnig (linux/windows)

and after opening PD files requiring Gem to work, things worked out greatly!!!

thank you so much slimfatboyslim!!!!! :)

now, another question, is there a place where i could find out more about connecting sensors to pd through usb/serial port? is there a recommendation regarding this? like electronic advice, types of connectors to be used and how to get PD talking to external microchips and other devices?

thanks galore!!!!

Best Regards

Tiago
