Analog input, analog output, serial output Reads an analog input pin, maps the result to a range from 0 to 255 and uses the result to set the pulsewidth modulation (PWM) of an output pin. Also prints the results to the serial monitor. ...

选一个Digital Output和一个Pulse Generator(在simulink/sources里面)如下图连接好。设置下Pulse Geneartor。更改自己需要的频率,占空比等。双击Digital Output修改相应的pin number设置完以后可以开始烧写了。按下图打开配置窗口选择对应的控制板型号然后设置端口(可以选自动,或手动)设置波特率(相当于IDE编程时setup()函数...
Pin number on the physical hardware, specified as a character vector. Example:D3orA1. Note If you connect to ESP32 board and the pin'smodeis set toAnalogInput, the pin number must always correspond to a digital pin. For details, seePin-mapping for ESP32 Boards. ...
Arduino IDE自然是从官网下载的。pinMode(pin, mode):设置引脚。第一个参数表示设置的引脚,第二个参数表示将要把引脚设置成的模式。digitalWrite(pin, value):输出信号。第一个参数为引脚,第二个参数为输出模式。HIGH即为高电平,LOW即为低电平。 set
