got TextEdit.app to write '.pdrc' file wit the instructions:
-path /usr/local/lib/pd/extra -lib Gem
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
