F_Byte_to_Temp : REAL

F_Byte_to_Temp : REAL 1:

This function converts a byte raw value into a REAL variable.

In EnOcean, temperature data are transmitted in a certain format, which is one byte in size. These data are usually scaled to a certain temperature value.

For example, a value is transmitted from a range of values from 0 to 40°C. The minimum and maximum data value and the raw value are transferred to the function. The output of the function then outputs the temperature as REAL variable.


byData  : BYTE;
minTemp : REAL := 0;
maxTemp : REAL := 40;

byData: Raw data.

minTemp: Minimum temperature.

maxTemp: Maximum temperature.
