Tedd OKANO / PCT2075

Component class library for PCT2075 and LM75B. The PCT2075 is a temperature-to-digital converter featuring +/-1 degree-C accuracy over -25 degree-C to +100 degree-C range. It uses an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output that is a drop-in replacement for other LM75 series thermal sensors.

/** PCT2075 & LM75B class library / PCT2075 & LM75B クラスライブラリ
 *
 *  Class library provides very simple interface to read sensor value
 *  クラスライブラリはセンサの値を読む非常にシンプルなインターフェースを提供します
 *
 *  Example / コード例:
 *  @code
 *  #include "mbed.h"
 *  #include "PCT2075.h"                //  or #include "LM75B.h"
 *  
 *  PCT2075 temp_sensor( p28, p27 );    //  or LM75B temp_sensor( p28, p27 );
 *  
 *  int main()
 *  {
 *      while(1) {
 *          printf( "temp = %7.3f\r\n", (float)temp_sensor );
 *          wait( 1 );
 *      }
