例如,如果连接到引脚3,则使用digitalPinToInterrupt(3)作为attachInterrupt()的第一个参数。 表1:Arduino 开发板的外部中断引脚 表2:Arduino 开发板的中断引脚对应的中断编号 2、一个从轮询到中断的代码改进 1) 轮询示例 方式1:轮询的方式按按钮,点亮LED,代码: //pins const unit8_t btn_pin = 2 ; const un...
To make matters more confusing, theattachInterruptdocumentationfalsely claims: For Uno WiFiRev.2, Due, Zero, MKR Family and 101 boards the interrupt number = pin number. TheattachInterruptdocumentation also specifically says that theattachInterrupt(pin, ISR, mode)syntax isnot recommended. http://forum...
1. spi针脚 The following table display on which pins the SPI lines are broken out on the different Arduino boards: Note that MISO, MOSI, and SCK are available in a consistent physical location on the ICSP header; this is useful, for example, in designing a shield that works on every boa...

This processor is used in a number of other microcontroller boards, including theArduino Zero,Arduino MKRZeroandArduino MKR 1000boards. Seeedstudio also makes theSeeeduino Cortex-M0+andSeeeduino Lotus Cortex-M0+, both of which support Grove connectors. Adafruit and Sparkfun also make boards using ...
Zero, it uses an ARM chip. However, the MKR1010 also includes WiFi and and a circuit to run from and recharge a LIPO battery. Although the MKR family of boards is not compatible with shields designed for the Uno, Arduino offers a selection of add-on boards for the MKR form factor ...

Here is my circuit for detecting zero crossing with Arduino (same circuit as this thread, but with the correction for the interrupt pin): Once again, I am using analogRead(A0) as an oscilloscope. The interrupts are detected fine, and my Interrupt Service Routine (ISR) is also being called...
