hi Guys, I'm trying to subscribe to rising edges on 8 GPIOs. I have found this online about the beaglebone (not black):
*A maximum of 66 GPIO pins are accessible from the expansion header. All of these pins are 3.3V and can be configured as inputs or outputs. Any GPIO can be used as an interrupt and is limited to two interrupts per GPIO Bank for a maximum of eight pins as interrupts.* Is the same true for the BBB? I've not tried all the ports, but I've only been able to get 3 interrupts working so far. Furthermore, how are the pins banked? The reference manual is silent on this subject. I found a table on page 70-72, which groups the GPIOs under "Mode 7: as belonging to 0,1,2, or 3 -- is this what is meant by different banks? What are the limitations on interrupts for the BBB? Why is this nowhere mentioned (that I could find??)?
