[問題] 請教程式設計

[shan83 (無盡深淵、寂靜虛空)]

小弟在arduino平台上做些小東西

我的程度沒有很高

有一個問題想請教各位

我有兩個獨立的程式想要合併

函式庫都有

獨立編譯可以過

我整合一起就GG了

可能port上會衝突

請問要怎麼解決?

那些部份需要修改嗎?

請具體一點

因為我程度不高...

謝謝各位

先附我整合的程式碼


#include <i2cmaster.h>
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);
const float lowReading = 60;
const float highReading = 75;
const unsigned char separatorCharacter = 255;

void setup() {
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  Serial.begin(9600);
  i2c_init();
  PORTC = (1 << PORTC2) | (1 << PORTC3);
  Serial.println("completed setup");

  lcd.begin(16, 2);
  for(int i = 0; i < 3; i++) {
    lcd.backlight();
    delay(250);
    lcd.noBacklight();
    delay(250);
  }
  lcd.backlight();

  lcd.setCursor(0, 0);
  lcd.print("Hello, world!");
  delay(1000);
  lcd.setCursor(0, 1);
  lcd.print("fuck up");
  delay(8000);
  lcd.clear();
}

float normf(float x, float low, float high) {
  float y = (x - low) * 255.f / (high - low);
  if (y > 255) {
    y = 255;
  }
  if (y < 0) {
    y = 0;
  }
  return y;
}

void loop() {
  int dev = 0x5A << 1;
  int data_low = 0;
  int data_high = 0;
  int pec = 0;

  i2c_start_wait(dev + I2C_WRITE);
  i2c_write(0x07);

  i2c_rep_start(dev + I2C_READ);
  data_low = i2c_readAck();
  data_high = i2c_readAck();
  pec = i2c_readNak();
  i2c_stop();

  double tempFactor = 0.02;
  double tempData = 0x0000;
  int frac;

  tempData = (double)(((data_high & 0x007F) << 8) + data_low);
  tempData = (tempData * tempFactor) - 0.01;
  float celcius = tempData - 273.15;
  float fahrenheit = (celcius * 1.8) + 32;


  float state = normf(fahrenheit, lowReading, highReading);

  Serial.print(celcius);
  Serial.print(" degrees C,");
  Serial.print(fahrenheit);
  Serial.println(" degrees F");

  lcd.setCursor(0, 0);
  lcd.print(celcius);
  lcd.print(" degrees C");
  lcd.setCursor(0, 1);
  lcd.print(fahrenheit);
  lcd.print(" degrees F");

  int r, g, b = 0;
  if (fahrenheit > 92) {
    r = 0;
    g = 1;
    b = 1;
  }
  else if (fahrenheit > 83) {
    r = 1;
    g = 0;
    b = 1;
  }
  else {
    r = 1;
    g = 1;
    b = 0;
  }
  int red = constrain((int)255 * r, 0, 255);
  int green = constrain((int)255 * g, 0, 255);
  int blue = constrain((int)255 * b, 0, 255);
  setLedColor(red, green, blue);
}
void setLedColor(int r, int g, int b) {
  analogWrite(8, r);
  analogWrite(9, g);
  analogWrite(10, b);
}

以下是錯誤訊息

不好意思有點雜亂

謝謝各位

推 chuegou: ...先學著看錯誤訊息
→ chuegou: multiple definition of `i2c_init()'
→ chuegou: 你有兩個一樣的函式  他問你要call哪一個
→ chuegou: 下面基本上都是同類型錯誤
一樣的是指名稱一樣
但功能不一樣?
還是完全一樣?
所以我去函式庫砍掉一個就好了嗎?

推 chuegou: 名稱  把他註解掉雖然不是好方法.但你可以試試看
→ chuegou: 不過運作起來會怎樣我也不肯定
好的 謝謝

推 felaray: 看起來就SoftI2CMaster裡面出包了.
→ felaray: 如果都引用同樣的函示庫,整合前應該也會出包吧
→ shan83: 整合前沒問題耶
推 god145145: 把第一個i2cmaster拿掉，編譯後再把缺的補回來
→ shan83: 好哦我試試，謝謝
