* Backport from ESP32 * Use new library layout (.../src) * Cleanup test case. * C++ style cast required. * Whitespace * Inlining via header has better baseline ROM footprint. * Reordered functions for better code-compare to master * Reduces ROM footprint some more. * Avoid unnecessary parameter passing - refactoring, same generated footprint. * Reformat example sources

Passing paramters to Ticker callbacks
|
|
|
|
Apart from void(void) functions, the Ticker library supports
|
|
functions taking one argument. This argument's size has to be less or
|
|
equal to 4 bytes (so char, short, int, float, void*, char* types will do).
|
|
|
|
This sample runs two tickers that both call one callback function,
|
|
but with different arguments.
|
|
|
|
The built-in LED will be pulsing.
