DigitalOutInterface Class Reference
[Device Interfaces]
#include <rtt/dev/DigitalOutInterface.hpp>
Detailed Description
A class representing a Digital Output device which can read or write a maximum of 32 bits at once.When there are N bits, the bits are numbered from Zero to N-1.
- Invariant:
- Bit 0 denotes the first digital output on the card.
No more than 32 bits can be addressed

Member Function Documentation
| virtual void switchOn | ( | unsigned int | n | ) | [pure virtual] |
Sets the n'th output on.
- Parameters:
-
n The number of the output to be switched on. The first output is number 0.
Referenced by __os_init().
| virtual void switchOff | ( | unsigned int | n | ) | [pure virtual] |
Sets the n'th output off.
- Parameters:
-
n The number of the output to be switched off. The first output is number 0.
| virtual void setSequence | ( | unsigned int | start_bit, | |
| unsigned int | stop_bit, | |||
| unsigned int | value | |||
| ) | [pure virtual] |
Sets a sequence of bits to pattern value between start_bit and stop_bit inclusive.
For example, setSequence(3, 3, 1) is equivalent to setBit(3, 1).
| virtual bool checkBit | ( | unsigned int | n | ) | const [pure virtual] |
Returns the status of bit n, starting from zero.
- Returns:
- true if the bit is 1, false otherwise.
Referenced by DigitalOutput::isOn().
| virtual unsigned int nbOfOutputs | ( | ) | const [pure virtual] |
Query the number of outputs of this card.
- Returns:
- the number of digital output channels addressable
