/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...
void analogSetPinAttenuation(uint8_t pin, adc_attenuation_t attenuation); pin选择特定引脚进行衰减设置。 attenuation 设置衰减。 analogSetWidth() Note:该功能仅适用于 ESP32 芯片。 该函数用于设置硬件采样位和读取分辨率。默认值为 12 位 (0 - 4095)。范围为 9 - 12。 void analogSetWidth(uint8_t ...
val = analogRead(analogPin);Serial.println(val);}这里还是要实现Matlab的即时读取和画图。Matlab代码如下:s = serial('COM3'); %定义串口对象set(s,'BaudRate',9600); %设置波特率sfopen(s); %打开串口对象sinterval = 10000; %这里开始的代码很Part1里的代码类似passo = 1;t = 1;x = 0;while(t...
附上官网对于AnalogPin的一段话,也是要求在analogRead之前将接口设置为INPUTDetails and CaveatsThe analogRead command will not work correctly if a pin has been previously set to an output, so if this is the case, set it back to an input before using analogRead. 小猪会轮滑 赫赫有名 13 这个最...
