外部中断函数 attachInterrupt(interrupt, , mode) 外部中断只能用到数字IO口2和3,interrupt表示中断口初始0或1,表示一个功能函数,mode:LOW低电平中断,CHANGE有变化就中断,RISING上升沿中断,FALLING下降沿中断。 detachInterrupt(interrupt) 中断开关,interrupt=1 开,interrupt=0 关。 中断使能函数 interrupts() 使能中断...
timerEnd(timer); timer = NULL; } } } The RepeatTimer example is in the Timer submenu, and it illustrates how to create an interrupt handler for the ESP32. The interrupt handler is a function called onTimer and it is attached to the timer and triggered every second. The button is read...
The used IMU MPU6050 communicates using I2C and to keep the libraries happy I decided to stick with the default pins A4 (SDA) and A5 (SCL). I will connect the interrupt pin in case I will need it in the future. Nano supports interrupts on pins 2 and 3 only as can be seenhere. Th...

This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based ...
Failed to run on ESP32 Arduino Core due to watchdog timer reset. 4 pixel horizontal offset when set to 128×32 resolution. Sketch runs only once on Arduino Nano 33 BLE Sense, immediately after uploading. Since Adafruitpublished the source code for this library, I thought I’d take a look...
we begin I want to make sure we’re all using the same terms. There are two main categories of interrupts: Hardware and Software. A Hardware interrupt is triggered by something outside of the chip like a button while a Software interrupt is triggered from inside the chip like a timer. ...
If it changes state every 10 seconds, as stated, the update() function will update the EEPROM as Duncan has stated. This is a very example to present for the use of the EEPROM. Reply Jet June 21, 2021 at 10:49 pm set all eeprom to FF then you save at address = address +1 . ...
The below circuit diagram shows how to use SPI on Arduino UNO, but you can follow the same procedure for Arduino Mega SPI Communication or Arduino nano SPI communication. Almost everything will remain the same except for the pin number. You have to check the pinout of Arduino nano or mega...
