It's only 3.3v but it's there. Someone just needs to write up an SIO driver for it and then put the GPIO pins in question into RS232 "mode". Yay multi-function GPIO pins! adrian On 14 May 2013 08:58, Tom Everett wrote: > Good morning ARM mailing list. > > I've been running FreeBSD on my Pi, and I've now got two XBee Pros which I > hope to connect.
