ADC0-ADC5 其实是作为 PC0-PC5 的第二功能存在的,分别对应 Arduino 定义 A0-A5。也正因为次,在 Arduino 的官方指南中提到,“The analog input pins can be used as digital pins, referred to as A0, A1, etc. ”。说的是,模拟输入口可以当数字口一样用。对于A0-A5来说,确实不错。但对于第一功能就...

ReadAnalogVoltage ADC并将值转换为电压值然后传输给串口 Digital BlinkWithoutDelay 没用delay实现led闪烁,没循环一次读取当前时间millis,然后比较到一定间隔取反led引脚 Button 用digitalRead直接读取按键引脚,然后直接输出给led引脚 Debounce 读取按键,上边沿时把LED输出取反,给按键加了消抖 ...
int analogPin = 5;int val = 0;void setup(){Serial.begin(9600);}void loop(){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...

All the cores I am doing are exposing only this linear range, so the macro in use (nalogInputToDigitalPin(P)) would be sufficient as well. In reality is just requires a variant.cpp where you keep any analog inputs from D0-D5 (or D0-D7). ...
