I'm pretty sure it's not there. >=A0 it would be great to merge that capability in. I've made a start on that this afternoon. I took the devbcm from plan9-bcm and stripped it down to just the gpio parts and renamed it devgpio. I've now got a B+ running with Richard's latest code that includes I2C and SPI and a first cut revision of devgpio. I'm watching an LED I wired up to it blinking driven by a program in user space as I type this. BLS =20 =20
