With millis(), it will take about 49.7 days to overflow. How to compute that:(Max value for unsigned long) divided by (number of milliseconds in one second) divided by (number of seconds in one hour) divided by (number of hours in one day)....

() * remove useless defines * improve api readability, add micro-second unit * update example * mock: emulate getCycleCount, add/fix polledTimeout CI test * + nano-seconds, assert -> message, comments, host test * allow 0 for timeout (enables immediate timeout, fix division by 0) *...
It’s possible to write one’s programs in such a way that they can accommodate an overflow/wraparound condition in the millis() function, but how does this actually work? In myprevious column, we discussed the fact that the time returned by the Arduino’s millis() function will overflow...
This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, Mega-AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, STM32F/L/H/G/WB/MP1, Teensy, Nano-33-BLE, etc.As Hardware Timers are rare, and very precious assets of any board, this ...
() and, I saw only a slight overall benefit to running the System.currentTimeMillis versus the (new Date ()).getTime (). 1 billion runs: (1000 outer loops, 1,000,000 inner loops): System.currentTimeMillis (): 14.353 seconds (new Date ()).getTime (): 16.668 secon...
This library enables you to use Interrupt from Hardware Timers onMBED RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO, usingArduino-mbed RP2040core AsHardware Timers are rare, and very precious assetsof any board, this library now enables you to use up to16 ISR-based Tim...
This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based ...
