In this tutorial, you’ll learn how to use ESP32 interrupt pins in Arduino Core. We’ll also discuss how to use interrupts and write your interrupt service routine (ISR) for ESP32 external interrupt GPIO pins. Then, we’ll move to the Arduino Core libraries that implement drivers for the...
(using DA Mellis' support files). The library enables you to assign an interrupt to pins on your chip that support them, and presents a common interface to all supported chips. This means that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc...
This is not currently possible with Arduino megaAVR Boards. Arduino megaAVR Boards'attachInterruptwas written to take a pin number as the first parameter, then convert the pin number to interrupt number insideattachInterruptusingdigitalPinToInterrupt, breaking from the convention established in Arduino AV...
The Arduino functionsattachInterrupt() anddetachInterrupt() can only be used for external interrupt pins. These are different interrupt sources, not discussed here. Timer interrupts A timer can generate different types of interrupts. The register and bit definitions can be found in the processor data ...
Also the minimal bootloader size on mega8. I didn’t really care to make it smaller because of that restriction. It’s been 3 years ago and I moved on to STM32, never been an Arduino fan too… you’re welcome to fork the repo and I’ll happily merge/discuss any changes you have....
There was plenty of code and examples that showed how you could read the mouse position and clicks from the Arduino, but [rehsd] still had to figure out a way to get that information into the 6502. In the end, [rehsd] connected one of the digital pins from the Arduino to an ...

Ports/Pins can be manually deactivated in the Settings file API and LowLevel option Full Port0-3 support .a linkage optimization (Arduino IDE) SeePCINT pin tableat the bottom for more details. Arduino Uno/Nano/Mini: All pins are usable Arduino Mega: 10, 11, 12, 13, 50, 51, 52, 53...
This 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.As Hardware Timers are rare, and very precious assets of any board, this ...
This library enables you to use Hardware Timers on an STM32H7-based Portenta_H7 board to create and output PWM to pins. These PWM channels, using Portenta_H7 Hardware Timers, still work even if other functions are blocking. Moreover, they are much more p
