`setup_timer` is a function in Arduino programming that is used to set up a timer for a specific interval or frequency. Here is the basic syntax of `setup_timer`: ```cpp setup_timer(timer_number, interval, interrupt_function, unit); ``` - `timer_number`: This indicates the specific...

// The callback function upon timer exit void progTimerCallBack1( TimerHandle_t progTimer1) { xTimerStop(progTimer1, 0); Serial.println("Timer 1 has Ended"); progState = 0; relay1Control = 0; state = 0; // If the callback function is called, the timer has ended, state should...
has shown in the function implementation below. Arduino_Core_STM32/libraries/SrcWrapper/src/HardwareTimer.cpp Lines 521 to 557 in8ff274a voidHardwareTimer::setOverflow(uint32_toverflow, TimerFormat_t format) { uint32_tARR_RegisterValue;
To call a function handler 10 times a second:Timer3.attachInterrupt(handler).setFrequency(10).start();In case you need to stop a timer, just do like this:Timer3.stop();And to continue running:Timer3.start();There are 9 Timer objects already instantiated for you: Timer0, Timer1, Timer...

We can useesp_sleep_enable_timer_wakeup(sleep_time_in_us)function which is available in the Arduino IDE. This function takes a single argument that denotes the sleeping time in microseconds. For example: esp_sleep_enable_timer_wakeup(sleep_time_in_us) ...
Returns a new handle to a GPIO device for a specific pin on the I/O switch. This function can only be called if there is an I/O switch in the design. gpio gpio_open_device(unsigned int device) Returns a handle to an AXI GPIO controller based either on the base address or device ...
Here are few pointers about using interrupts in the ESP8266, as well as in any Arduino based system. –Keep your Interrupt Service Routine (ISR) short. ISR is another name for the callback function. –Do not use “serial print” commands in an ISR. The serial commands also use interrupts...
Just like using button to control LED in the previous chapter, it also deals with the relationship of "button-UNO master control-LED". The difference here is that it adds a delay before turning off and simplifies the switch function.
