  • A nesCapplication consists of one or more components assembled, or wired, to form an application executable. • Components define two scopes: • one for their specification which contains the names of their interfaces, and • a second scope for their implementation. COMPONENT A SPECIFICATION IMPLEMENTATION 3 NesC (I)
• 4.
  •A component providesand uses interfaces. •The provided interfaces are intended to represent the functionality that the component provides to its user in its specification. •The used interfaces represent the functionality the component needs to perform its job in its implementation. 4 NesC (II)
• 5.
  • Interfaces arebidirectional: they specify a set of commands, which are functions to be implemented by the interface's provider, and a set of events, which are functions to be implemented by the interface's user. For a component to call the commands in an interface, it must implement the events of that interface. •The set of interfaces which a component provides together with the set of interfaces that a component uses is considered that component's signature. 5 NesC (III)
• 6.
  •There are 2types of components in nesC: - Modules: provide the implementations of one or more interfaces. - Configurations: used to assemble other components together, connecting interfaces used by components to interfaces provided by others. 6 Components

  • Commonly usedunits: • int is NOT used • bool is also used 12 NesC variables

  • An alternativeto console programming is using a TinyOS plug-in for the Eclipse IDE. • In this IDE it is possible to compile and install programs in motes •We will use this IDE to speed up the lessons. 13 Eclipse IDE

  1. Interface Ledshas commands to control the 3 leds on the mote. (led0, led1, led2).Try each of them and install them on the mote 2. Add a Timer to blink the Leds periodically, showing a binary timer using the 3 leds. 3. Configure the User Button to do a complete routine with the Leds 4. Pack the previous subroutine in a new component with your own interface. 14 Exercises
