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 ...
在Arduino世界中,Servo库在Arduino Uno上使用timer1(Arduino Mega上的timer5)。 定时器2: Timer2是一个8bit定时器,在Arduino工作中,tone()函数,IRremote库文件使用timer2。 Timer3,Timer4,Timer5: 定时器3,4,5仅适用于Arduino Mega主板。 这些定时器都是16位定时器。 三、定时器配置代码 int toggle0,toggle1...
that on the Arduino Uno and Mega you don't give it an interrupt number, as perhttp://arduino.cc/en/Reference/attachInterrupt. Rather, your first argument is a pin number of a pin that's supported on that chip (seehttps://github.com/GreyGnome/EnableInterrupt/wiki/Usage#pin--port-...
· MsTimer2 - uses the timer 2 interrupt to trigger an action every N milliseconds.· OneWire - control devices (from Dallas Semiconductor) that use the One Wire protocol.· PS2Keyboard - read characters from a PS2 keyboard.· Servo - provides software support for Servo motors on any pins...
wokwi-arduino-mega参考 Arduino Mega 2560。由ATmega2560芯片提供支持,该芯片拥有256K字节的Flash程序内存、8k字节的SRAM和4K字节的EEPROM。该板具有54个数字引脚、16个模拟输入引脚和4个串行端口。它以16MHz运行。 引脚名称 引脚0到53是数字GPIO引脚。引脚A0至A15除了是数字GPIO引脚外,还兼作模拟输入引脚。
The next line in the setup()-function attaches an interrupt to pin two. Note how I set it to detect falling edges. The pin will normally be in a HIGH state unless pulled low, and when that happens, I want the Arduino to call a custom function to react to that state change. In ...
You must use // 38400 or slower in these cases, or use some kind of external separate // crystal solution for the UART timer. // initialize device Serial.println(F("Initializing I2C devices...")); mpu.initialize(); pinMode(INTERRUPT_PIN, INPUT); // verify connection Serial.println(F(...
