I am interested in using your gumstix for an embedded project for a marketing buddy of mine. I am not sure which computer or daughterboards to select. and i am looking for a lil help What i need to do is hook-up your computer with a USB barcode reader swipe like the one below (yes barcode not mag stripe) link below. http://www.barcodecatalog.com/cgi-local/hall.pl? com=product&field1=000000172 I want to write a perl or python app that will stay running and just wait for someone to swipe the card and when swipped compare the data to a local file and if a certain condition is met i need to send a control signal to a second usb or serial port to trigger a relay which opens a door. this is not for a door control system (access control) its for a marketing gimic box. So in short my question to the list is which gumstix computer is best suited for this purpose, which accessories/ power supplies do i need (or can i use a battery) and how do i interface with the unit to get a bash or perl or python app compiled and loaded on the machine from my mac. Thanks in advance mike |
