Web1 hour ago · The overloads can be generated using: auto func_overloads = OVERLOADS (func, 1, 2) While this approach works, I would prefer to reduce the amount of preprocessor code generation involved in this. There are two problematic parts: func cannot be passed into a template, since this would already require it to be the correct overload. WebJan 1, 2007 · ISR overhead can be split into two parts, fixed and variable. Fixed overhead is associated with the CPU detecting that an interrupt has occurred, vectoring to the ISR, clearing any required flags to prevent the ISR from being re-entered, and finally executing the return from interrupt instruction.
