ESP32 Arduino 读取ADC速度问题？
void setup () { Serial.begin(115200); } void loop () { unsigned long begt = 0, begt2 = 0, runt = 0; int v1 = 0; begt = micros();//记录开始微秒数 for (unsigned long i = 0; i < 1000000; i++) { v1 = analogRead(32); } begt2 = micros();//记录结束微秒数 runt = begt2 - begt; //计算用时 Serial.println(String(runt)); } //输出结果...
