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(
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。
arduino中digital+Write(LEDpin,state)是什么意思? 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。
So in that case you have to write your ownlibrary. Like in our case,wewere trying to interface the resistive touch scren with ourArduino MEGA board, we searched a lot over the internet, & got2 versions of library for the same, but they wereobsolete, working!So decided to write our ow...
