Shield pin configuration

2.4 GPIO interrupt support

All GPIO inputs on the Intel® Edison platform are interrupt-capable, and all interrupt types are supported on all

inputs. Table 5 lists the specific edge- and level-triggered interrupt types that are supported on each pin.

1. Level-triggered interrupts are not supported by the Arduino* library, a limitation of the GPIO sysfs interface.

2.5 Miscellaneous GPIOs

The GPIOs listed in Table 6 are used for other platform functions and for Arduino shield compatibility.
