Function Documentation

◆ T_fam10()

FUNCTION_AS_SHORT T_fam10 ( BYVAL_AS_UBYTE_PTR Rom )

Compute the temperature for a series 10 sensor (old format).

Parameters

Rom	The pointer where to find the data received from the device.

Returns: The temperature (high byte = decimal value, low byte = digits).

This function decodes the temperature value from a DS18S20 sensor (such sensors have &h10 in the lowest byte of their ID). The returned value contains the temperature in grad Celsius in the high byte and the decimal places in the low byte. Divide the value by 256 to get a real number containing the temperatur in grad Celsius.

Parameter Rom is usually the adress of PruW1::DRam[4].

Since: 0.0

◆ T_fam20()

FUNCTION_AS_SHORT T_fam20 ( BYVAL_AS_UBYTE_PTR Rom )

Compute the temperature for a series 20 sensor (new format).

Parameters

Rom	The pointer where to find the data received from the device.

Returns: The temperature (high byte = decimal value, low byte = digits).

This function decodes the temperature value from a newer Dallas sensor (the lowest byte in the ID of such sensors is either &h20, &h22, &h28, &h3B or &h42). The returned value contains the temperature in grad Celsius in the high byte and the decimal places in the low byte. Divide the value by 256 to get a real number containing the temperatur in grad Celsius.
