Richard has an i2c and spi driver for the pi. I grafted the inferno i2c file system interface on top of Richards driver, though the sub addressed reads are awaiting my return from holiday.
there is a pi gpio and pwm driver which has a pi audio module which sits on top. this produces strange noises with a pi2 which I will dig into shortly. I think the pi is a wonderful terminal, the only app which would really benefit from Gbit ether is Remote Desktop (imho) I would love a similar machine with Gbit ether and 2 or 3 sata 3s to replace my ageing file server. -Steve > On 6 Aug 2015, at 00:12, Skip Tavakkolian <skip.tavakkol...@gmail.com> wrote: > > RPI's running something like plan9-bcm (check github) where gpio is exposed > should work.
