![]() ![]() So your function might not be executed, and the result would be disastrous. But what if another function is blocking the loop() or setup(). You normally use a software timer to poll, or even place the function in loop(). Imagine you have a system with a mission-critical function, measuring water level and control the sump pump or doing something much more important. ![]() The elapsed time then is very unaccurate Why using ISR-based Hardware Timer Interrupt is better In loop(), using delay() function as an example. You'll see blynkTimer Software is blocked while system is connecting to WiFi / Internet / Blynk, as well as by blocking task This non-being-blocked important feature is absolutely necessary for mission-critical tasks. You can also have many (up to 16) timers to use. The ISR_Timer_Complex example will demonstrate the nearly perfect accuracy compared to software timers by printing the actual elapsed millisecs of each type of timers.īeing ISR-based timers, their executions are not blocked by bad-behaving functions / tasks, such as connecting to WiFi, Internet and Blynk services. This important feature is absolutely necessary for mission-critical tasks. Therefore, their executions are not blocked by bad-behaving functions / tasks. The most important feature is they're ISR-based timers. Now with these new 16 ISR-based timers, the maximum interval is practically unlimited (limited only by unsigned long milliseconds) while the accuracy is nearly perfect compared to software timers. Timers' interval is very long ( ulong millisecs). This library enables you to use Interrupt from Hardware Timers on an NRF52-based board using mbed-RTOS such as Nano-33-BLE.Īs Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while consuming only 1 Hardware Timer.
