This file provides utilities for temporarily disabling (suppressing) interrupts of various kinds in a block of code. It uses the C++ RAII paradigm to ensure interrupt state is restored automatically when the block of code is exited. While all interrupts can be suppressed, tools are provided that allow more selective control of which interrupts are suppressed. More...

Classes | |
| class | Interrupts::AllOff |
| This class defines an object that disables all interrupts during its lifetime. Interrupt state is restored by the object's destructor when the object goes out of scope. More... | |
| class | Interrupts::ExternalOff |
| This class defines an object that disables selected external interrupts during its lifetime. The selected external interrupts are restored by the object's destructor when it goes out of scope. More... | |
| class | Interrupts::PinChangeOff |
| This class defines an object that disables selected pin change interrupts during its lifetime. The selected pin change interrupts are restored by the object's destructor when it goes out of scope. More... | |
Namespaces | |
| Interrupts | |
| This namespace bundles various utility classes designed to suppress selected interrupts using the RAII idiom. | |
Enumerations | |

| This enum lists the external interrupts that can be suppressed (disabled). To pass more than one external interrupt, simply "or" them. More... | |

Detailed Description
This file provides utilities for temporarily disabling (suppressing) interrupts of various kinds in a block of code. It uses the C++ RAII paradigm to ensure interrupt state is restored automatically when the block of code is exited. While all interrupts can be suppressed, tools are provided that allow more selective control of which interrupts are suppressed.
