我一直在努力將數據從加速度傳感器保存到文本文件。但在搜索了幾個小時之後,我發現的方法沒有奏效。這是我現在的計劃。將Arduino傳感器數據保存到文本文件
// Accelerometer sensor program
const int ar1 = A5;
const int ar2 = A4;
const int ar3 = A3;
int x = 0;
int ov1 = 0;
int y = 0;
int ov2= 0;
int z = 0;
int ov3= 0;
void setup() {
// initialize the communications
Serial.begin(9600);
}
void loop() {
analogReference(EXTERNAL); //connect 3.3v to AREF
// X axis
// Read the analog
x = analogRead(ar1);
// Range of analog out
ov1 = map(x, 0, 1023, 0, 255);
delay(2);
// Y axis
y = analogRead(ar2);
ov2 = map(y, 0, 1023, 0, 255);
// Z axis
delay(2);
z = analogRead(ar3);
ov3 = map(z, 0, 1023, 0, 255);
// Should print to the monitor
// Output for X axis
Serial.print("Xsensor1 = ");
Serial.print(x);
Serial.print("\t output1 = ");
Serial.println(ov1);
// Output for Y axis
Serial.print("Ysensor2 = ");
Serial.print(y);
Serial.print("\t output2 = ");
Serial.println(ov2);
// Output for Z axis
Serial.print("Zsensor3 = ");
Serial.print(z);
Serial.print("\t output3 = ");
Serial.println(ov3);
// Should repeat every second
delay(1000);
什麼我發現似乎做我想做什麼,這個問題是Arduino的不希望運行它,說「進口」的範圍未聲明。我已經嘗試安裝一些庫,但是我找不到導入是其中一部分的確切庫,或者PrintWriter。以下是導致問題的代碼:
import processing.serial.*;
Serial mySerial;
PrintWriter output;
void setup() {
mySerial = new Serial(this, Serial.list()[0], 9600);
output = createWriter("data.txt");
}
void draw() {
if (mySerial.available() > 0) {
String value = mySerial.readString();
if (value != null) {
output.println(value);
}
}
}
void keyPressed() {
output.flush(); // Writes the remaining data to the file
output.close(); // Finishes the file
exit(); // Stops the program
}
在此先感謝。
