標題: 想請問有關陣列的問題
大家好目前在做陣列的研究，遇到了一些麻煩，在關於陣列要編譯時，沒辦法編譯，想請問大家那裡有問題謝謝

#include <Wire.h>

#include <Adafruit_AMG88xx.h>

Adafruit_AMG88xx amg;

float pixels[AMG88xx_PIXEL_ARRAY_SIZE];
float pixels[8][8];
void setup()
{
Serial.begin(115200);
bool status;
status = amg.begin();
if (!status) {}
delay(100);
}

void loop()
{
amg.readPixels(pixels);
for (int i=1; i<=AMG88xx_PIXEL_ARRAY_SIZE; i++)
{
      Serial.print('C');
      Serial.print(pixels[i-1]);
      while (Serial.available()<=0) {}
      Serial.read();
}

amg.readPixels(&pixels[0][0]);

  //第一列
  Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][0]));             Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][1])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][1]));             Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[1][1])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[1][0]));             Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[1][0])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][0]));             Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][0])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][0] - pixels[0][0]));

  for (int i = 0; i < 1; i++) {
  for (int j = 1; j < 7; j++) {
  Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j]));             Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j+1])/sqrt(2),2); Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j+1]));          Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i+1][j+1])/sqrt(2),2); Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i+1][j]));          Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i+1][j-1])/sqrt(2),2); Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j-1]));          Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j-1])/sqrt(2),2); Serial.print("ab");
  Serial.print(abs(pixels[i][j] - pixels[i][j]));
  }
  }

  Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][7]));             Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][7])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][7]));             Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[1][7])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[1][6]));             Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][7])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][6]));             Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][6])/sqrt(2),2);    Serial.print("ab");
  Serial.print(abs(pixels[0][7] - pixels[0][7]));
}

兩個不同的陣列, 但名稱一樣
一個是一維陣列, 另一個是二維陣列
float pixels[AMG88xx_PIXEL_ARRAY_SIZE];
float pixels[8][8];
去掉其中一個即可,
當然和它相應的程式也要一併拿掉
