This is a rewrite of the Kinetis GPIO driver which follows the refactored API in [1]. Pins are specified using the GPIO_PIN(PORT_x, y) macro, e.g. GPIO_PIN(PORT_E, 25) for the PTE25 pin. The interrupt pin handling is now implemented as a linked list, this is more memory efficient, but with a minor variation in interrupt latency depending on in what order the pins were initialized at runtime. Because the linked list entries are taken from a shared pool, there is also the possibility of running out of available configuration slots, define the preprocessor macro GPIO_INT_POOL_SIZE in periph_conf.h if you need more than 16 pins configured for interrupts in the same application.

The friendly Operating System for IoT!
FEATURES
RIOT OS is an operating system for Internet of Things (IoT) devices. It is based on a microkernel and designed for
- energy efficiency
- hardware independent development
- a high degree of modularity
Its features comprise
- a preemptive, tickless scheduler with priorities
- flexible memory management
- high resolution timers
- virtual, long-term timers
- the native port allows to run RIOT as-is on Linux, BSD, and MacOS. Multiple instances of RIOT running on a single machine can also be interconnected via a simple virtual Ethernet bridge
- Wiselib support (C++ algorithm library, including routing, clustering, timesync, localization, security and more algorithms)
- IPv6
- UDP
- 6LoWPAN
- NHDP
GETTING STARTED
- You want to start the RIOT? Just follow our Getting started documentation
- The RIOT API itself can be built from the code using doxygen. The latest version is uploaded daily to http://riot-os.org/api.
USING THE NATIVE PORT WITH NETWORKING
If you compile RIOT for the native cpu and include the nativenet module, you can specify a network interface like this: PORT=tap0 make term
SETTING UP A TAP NETWORK
There is a shellscript in RIOT/dist/tools/tapsetup called tapsetup which you can use to create a network of tap interfaces.
USAGE To create a bridge and two (or count at your option) tap interfaces:
./dist/tools/tapsetup/tapsetup [-c [<count>]]
CONTRIBUTE
To contribute something to RIOT, please refer to the development procedures and read all notes for best practice.
