The Arduino functionsattachInterrupt() anddetachInterrupt() can only be used for external interrupt pins. These are different interrupt sources, not discussed here. Timer interrupts A timer can generate different types of interrupts. The register and bit definitions can be found in the processor data ...
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 ...

. Depending on what the rest of the operating system is doing (WiFi, PWM, etc.), it will interrupt you when triggered, but it isn’t at an exact time. It will be close. Keep that in mind. You may see jitter in the timing. The faster interval you set for the os_timer, the ...
