The Arduino Nano has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega328 provide UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An FTDI FT232RL on the board channels this serial commun...

External interrupts All digital pins (all analog pins can also be used as interrupt pins, but will have duplicated interrupt numbers) LED_BUILTIN D13 USB Native in the SAMD21 processor Inertial measurement unit (IMU) LSM6DS3 (6-axis) PCB size 18 x 45 mm Weight 5 g (with headers) Cost...
Within the Hardware interrupt there are two categories: External interrupts and Pin Change Interrupts. The nomenclature here is confusing since all hardware interrupts are external to the chip. But the things we are now calling External Interrupts are limited to only a couple pins, while the Pin ...
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a ...
带中断的数字引脚 attachInterrupt()的第一个参数是中断号。 通常,您应该使用digitalPinToInterrupt(pin)将实际的数字引脚转换为特定的中断号。 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 ...
