為什麼這篇arduino lcd函式庫鄉民發文收入到精華區：因為在arduino lcd函式庫這個討論話題中，有許多相關的文章在討論，這篇最有參考價值！作者shan83 (無盡深淵、寂靜虛空)看板ASM標題[問題] 請教程式設計時間Fri Jun 3...
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 06/03 15:25
→ chuegou: multiple definition of `i2c_init()' 06/03 15:25
→ chuegou: 你有兩個一樣的函式 他問你要call哪一個 06/03 15:26
→ chuegou: 下面基本上都是同類型錯誤 06/03 15:27
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 06/03 17:40
→ chuegou: 不過運作起來會怎樣我也不肯定 06/03 17:41
好的 謝謝※ 編輯: shan83 (61.230.53.137), 06/03/2016 22:29:02
推 felaray: 看起來就SoftI2CMaster裡面出包了. 06/04 21:15
→ felaray: 如果都引用同樣的函示庫,整合前應該也會出包吧 06/04 21:16
→ shan83: 整合前沒問題耶 06/05 11:10
推 god145145: 把第一個i2cmaster拿掉，編譯後再把缺的補回來 06/05 22:05
→ shan83: 好哦我試試，謝謝 06/06 02:58
