SHT-15 - 2 把SHT-15讀到的數據存到SD Card

事實顯示鼓起勇氣把4x USD的SHT-15焊下去之前，只能用手按住。

首次用Fritzing的成果，用MicroSD Shield取代WaveShare那個MicroSD板子。自己弄了一個SHT-15的component，設定connections好累，不過SHT-15圖好像選太大張。

#include <SD.h>
#include <SHT1x.h>

/*
 * SHT 15 - 3
 */
 
#define DataPin 6    // DATA
#define ClockPin 5   // SCK
#define CSPIN 10 // SD CS pin

SHT1x sht1x( DataPin, ClockPin );
File myLogFile;

void setup() {
  Serial.begin( 9600 );
  Serial.print( "Initializing SD card..." );
  pinMode( 10, OUTPUT );
  
  if( !SD.begin( CSPIN ) ) {
    Serial.println( "initialization faild!" );
    return;
  }
  Serial.println( "initialization done." );
}

void loop() {
  float temp_c, temp_f, humidity;
  String log_msg = "";
  
  temp_c = sht1x.readTemperatureC();
  temp_f = sht1x.readTemperatureF();
  humidity = sht1x.readHumidity();
  
  log_msg.concat( (long) temp_c );
  log_msg += ",";
  log_msg.concat( (long) temp_f );
  log_msg += ",";
  log_msg.concat( (long) humidity );
  myLogFile = SD.open( "sht15.txt", FILE_WRITE );
  if( myLogFile ) {
    Serial.println( "Writing..." );
    myLogFile.println( log_msg );
    myLogFile.close();
    Serial.println( log_msg );
    Serial.println( "done." );
  } else {
    Serial.println( "error opening sht15.txt" );
  }
  
  delay( 1000 );
}

看SD卡上的檔案～～ 讀到負值的就是因為手沒按著SHT-15，還是要焊啊～～

氣象站記錄竟然沒有時間，下一步玩玩看能不能玩得起來PCF8563P...
