Example does not work correctly at negative temperatures

[lcgamboa]

The example does not work correctly at negative temperatures in DS1621.
To solve the problem, it is necessary to make a casting to char on line 98 for the value to be interpreted as negative.
The code below :

TinyWireM/examples/Tiny85_Temp_LCD_RTC/Tiny85_Temp_LCD_RTC.pde

Line 98 in bd396b8

tempC = TinyWireM.receive(); // get the temperature

needs to be changed to:

  tempC = (char)TinyWireM.receive();    // get the temperature
