Why do we need this ESP32TimerInterrupt libraryFeaturesThis library enables you to use Interrupt from Hardware Timers on an ESP32-based board.As 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 ...
I moved most of my code to a library but one particular function call gives me an error when compiling. This is the function needed for the timerAttachInterrupt(): Code: Select all void IRAM_ATTR TriggerTimer::cdInterrupt(){ //some codes } This is how I used the attachTimerInterrupt...

One better solution is to set up a timer interrupt and periodically check for the connection status or even implement a timeout mechanism after which we can re-attempt the connection process. There is also an even better solution which is to use the WiFi Events callback functions for ESP32 ...
This ESP32 tutorial will explain and solve a particular problem of sampling the analog-to-digital converter (ADC) from a timer interrupt. We will use the Arduino IDE. Even if it is one of the worst IDEs out there in terms of feature sets, the Arduino IDE is at least easy to set up...
On the next rising edge, an interrupt is fired, and the CPU suspends the main program and stops the timer. Now, the timer count can tell us the total time (T) or period of the signal. To get the frequency we’ll do (F = 1/T) and we’re done. ...
EPIT 的全称是: Enhanced Periodic Interrupt Timer,直译过来就是增强的周期中断定时器,它主要是完成周期性中断定时的。学过 STM32 的话应该知道, STM32 里面的定时器还有很多其它的功能,比如输入捕获、 PWM 输出等等。但是 I.MX6U 的 EPIT 定时器只是完成周期性中断定时的,仅此一项功能!至于输入捕获、 PWM 输出...

Why do we need this TimerInterrupt_Generic libraryFeaturesThis 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....
