attachInterrupt (digitalPinToInterrupt(GPIO), ISR, mode) digitalPinToInterrupt(GPIO) :中断引脚,除GPIO16都可以设置中断。 eg: digitalPinToInterrupt(14) ISR : 中断服务例程。功能应尽可能简单,以便处理器快速恢复主程序的执行。最好的方法是使用全局变量、在 loop() 中检查并清除该标志并执行代码。 mode : ...
attachInterrupt函数中的中断矢量参数与引脚编号不同,并且在 Arduino 板之间可能会有所不同。获取此数字的(更好)方法是使用digitalPinToInterrupt函数。 该函数的名称也是其描述,它接受引脚编号并返回中断向量编号。 您可以直接在attachInterrupt 函数中使用digitalPinToInterrupt。 attachInterrupt(digitalPinToInterrupt(pin),ISR...
Serialobject works much the same way as on a regular Arduino. Apart from hardware FIFO (128 bytes for TX and RX) HardwareSerial has additional 256-byte TX and RX buffers. Both transmit and receive is interrupt-driven. Write and read functions only block the sketch execution when the respecti...
Specifications: Operating Temperature: 1 Dissipation Power: 1 Customization: Yes Pin Configuration: 11 digital input/output pins, all with interrupt/PWM/I2C support (except D0) Analog Input: 1 analog input (maximum 3.2 V input) Connectivity: Micro USB Compatibility: Arduino, NodeMCU Additional Featur...
Interrupt Pins We can use any GPIO pin for interrupts except GPIO16. Wake Up To wake up ESP8266 from deep sleep using GPIO16 by connecting it to RST pin. This is a topic for another article. On board LED Mostly development boards have one or more built-in LEDs. The LED built on the...
Pin interrupts are supported throughattachInterrupt,detachInterruptfunctions. Interrupts may be attached to any GPIO pin, except GPIO16. Standard Arduino interrupt types are supported:CHANGE,RISING,FALLING. Pin Functions The most usable pin functions are mapped to the macroSPECIAL, so callingpinMode(pin...

arduino开发ESP8266学习笔记四---舵机 使用时发现会有ESP8266掉电的情况,应该是板上的稳压芯片的限流导致的,观测波形,发现当舵机运转时,电源线3.3V不再是稳定的3.3V,大概是在3.0V到3.3V范围内高频振动,这应该是ESP8266掉电的原因,可以将舵机电源连接到另一个电源上。当舵机使用外部电源的时候,一定要将舵机的电源...
D1 Mini NodeMcu Lua 4M Bytes WLAN WiFi Internet Development Board Base on ESP8266 ESP-12F for Arduino, 100% Compatible with WeMos D1 Mini. 11 digital input / output pins, all pins with interrupt / PWM / I2C / support 1 line (except D0); 1 analog input(3.2V max input). Micro USB...
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...
