How do I use lambda functions in Arduino?
Sep 24, 2020 · How can I use a lambda function in Arduino? std::function is not supported by the Arduino environment. (: as mentioned by KIIV in a comment, it's supported on ARM targets, but not on AVR.) You can, however, pass a non-capturing lambda to a function that expects a plain function pointer. For example, given. T value = initial;
Are anonymous function or lambda possible with UNO ... - Arduino Forum
Nov 22, 2016 · As I see this, the lambda function is created as an anonymous lambda function and then stored in _status_cb or at least a pointer to it. now later on this can be ran when the _status_rx() is triggered and data is passed to the lambda function.

Function as Parameter/Argument (lambda function) - Arduino Forum
Mar 5, 2022 · For a simple one-line function, it's easier to see what's going on if it's defined inline with the code it's related to. Another great benefit of lambda functions is that they can capture variables from the surrounding scope. This is very useful if …
Using lambdas as callback functions - Arduino Stack Exchange
Jan 31, 2021 · As @timemage explains in a comment, you cannot pass a capturing lambda to a function that expects a plain pointer to function.
