![]() 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 ESP8266-based board.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. Why do we need this ESP8266TimerInterrupt library Features Please have a look at HOWTO Fix Multiple Definitions Linker Error ISR_16_Timers_Array_OneShot on ESP8266_NODEMCU_ESP12E ISR_16_Timers_Array_Complex on ESP8266_NODEMCU_ESP12E ISR_16_Timers_Array on ESP8266_NODEMCU_ESP12E ![]() Change_Interval on ESP8266_NODEMCU_ESP12E TimerInterruptTest on ESP8266_NODEMCU_ESP12E 2.4 Set One-Shot Hardware Timer Interval.2.3 Set Hardware Timer Interval and attach Timer Interrupt Handler functions.2.2 Init Hardware Timer and ISR-based Timer.Using 16 ISR_based Timers from 1 Hardware Timer 1.3 Set Hardware Timer Frequency and attach Timer Interrupt Handler function.1.2 Set Hardware Timer Interval and attach Timer Interrupt Handler function.How to use PWM analogWrite() functions while using this library ESP8266 has only 2 hardware timers, named Timer0 and Timer1 HOWTO Use PWM analogWrite() with ESP8266 running Timer1 Interrupt.HOWTO Fix Multiple Definitions Linker Error.Why using ISR-based Hardware Timer Interrupt is better.Why do we need this ESP8266TimerInterrupt library.
