Close, the BBB has 69 and it is 3.3V. You can get all the BBB information on the Wiki, including the SRM.
http://www.elinux.org/Beagleboard:BeagleBoneBlack Interrupts are covered in the TRM for the processor. Pin muxing is also covered there. Banks mean pin mux modes. The SRM does not reprint the datasheets and technical manual for the all the parts inside it. Sort of like a waste of time. http://www.ti.com/product/am3358 for the TRM Gerald On Thu, Oct 23, 2014 at 8:54 PM, <[email protected]> wrote: > hi Guys, > > I'm trying to subscribe to rising edges on 8 GPIOs.
