March 4, 2022 - I have seen a couple of examples that use the SysTick timer to count the rotations on a rotary encoder, like this example for the blue pill . I was able to port that example to ESP32 (based on ESP32-Arduino code) as: static void IRAM_ATT...

August 5, 2025 - Timer interrupts are crucial in the use of ESP32 timer interrupt programming projects for accurate timing control. If you want something to occur on schedule, ESP32 timer interrupts give you the accuracy required. A timer interrupt is a dedicated interrupt that operates as a high-precision clock, counting and controlling time events with microsecond precision.

void noOsSystickHandler() { } // empty void osSystickHandler() __attribute__((weak, alias("noOsSystickHandler"))); void SysTick_Handler(void) { HAL_IncTick(); HAL_SYSTICK_IRQHandler(); osSystickHandler(); }

February 17, 2025 - In this tutorial, you’ll learn how to use ESP32 internal Timers & generate Timer Interrupt events in Arduino IDE. We’ll discuss how ESP32 Timers work, how to configure ESP32’s Timers, and how to generate periodic interrupts to synchronize the execution of logic within your project.

July 19, 2022 - The Arduino environment can be extended through the use of libraries. Libraries provide extra functionality for use in sketches. To use a library in a sketch, select it from Sketch > Import Library.
