在 Arduino 程序中,digitalWrite(LEDpin, state) 是一个函数,用于将电平写入数字引脚。该函数有两个参数:- LEDpin:数字引脚的编号。- state:布尔值,表示要写入的电平。如果 state 为 HIGH,则表示将高电平写入引脚;如果 state 为 LOW,则表示将低电平写入引脚。因此,digitalWrite(LEDpin, state...
arduino中的serial .available()和serial.read()是什么意思 有什么用 Serial.available() 的意思是:返回串口缓冲区中当前剩余的字符个数。一般用这个函数来判断串口的缓冲区有 人造草坪公司爱步体育设施,各类场地厂家_人造草坪每平米价格 爱步体育设施,提供专业场地施工及检测设备、为用客户提供规划设计、铺设施工、保...
这是一个抽象函数,其作用是向指定的数字量接口写入数据。在这个例子中,要写入的数字量接口是LED对应的管脚,写入的数据是目标状态,亮或灭。
The Teensy has 21 digital I/O pins and the Teensy++ has 38, which you can use to control many types of devices or read information. You can access the pins by their number, or using their pre-defined names shown in the table. These names match the printing on the circuit board. Inpu...
Note 1: In the Arduino implementation ofdigitalWriteanddigitalReadthere is a check whether the affected pin is used by a timer. It seems 'silly' to do this each time a pin is written or read - as the Arduino developer(s) themselves write in a source comment - so I d...
