BusOut Class Reference

Create an BusOut, connected to the specified pins.

Parameters:

p<n>	DigitalOut pin to connect to bus bit <n> (p5-p30, NC)

Note:

It is only required to specify as many pin variables as is required for the bus; the rest will default to NC (not connected)

Add the class to the list of classes which can have static methods called via rpc (the static methods which can be called are defined by that class' get_rpc_class() static method).

Definition at line 143 of file Base.h.

Returns a pointer to an array describing the rpc methods supported by this object, terminated by either RPC_METHOD_END or RPC_METHOD_SUPER(Superclass).

Example

 class Example : public Base {
     int foo(int a, int b) { return a + b; }
     virtual const struct rpc_method *get_rpc_methods() {
         static const rpc_method rpc_methods[] = {
             { "foo", generic_caller<int, Example, int, int, &Example::foo> },
             RPC_METHOD_SUPER(Base)
         };
         return rpc_methods;
     }
 };

Reimplemented from Base.

Lookup and return the object that has the given name.

Parameters:

name	the name to lookup.
len	the length of name.

Returns the name of the object.

Returns:

The name of the object, or NULL if it has no name.

A shorthand for read()

A shorthand for write()

Read the value currently output on the bus.

Returns:

An integer with each bit corresponding to associated DigitalOut pin setting

Registers this object with the given name, so that it can be looked up with lookup.

If this object has already been registered, then this just changes the name.

Parameters:

name	The name to give the object. If NULL we do nothing.

Use the lookup function to lookup an object and, if successful, call its rpc method.

Returns:

false if name does not correspond to an object, otherwise the return value of the call to the object's rpc method.

Call the given method with the given arguments, and write the result into the string pointed to by result.

The default implementation calls rpc_methods to determine the supported methods.

Parameters:

method	The name of the method to call.
arguments	A list of arguments separated by spaces.
result	A pointer to a string to write the result into. May be NULL, in which case nothing is written.

Returns:

true if method corresponds to a valid rpc method, or false otherwise.

Write the value to the output bus.

Parameters:

value

An integer specifying a bit to write for every corresponding DigitalOut pin
