Pressure / Temp. in set unit
104 as float – Lo Word (n/a for O
Register Configuration A
15 14 13 12
A1: Unsigned Short. Range = 0...65535
A2: Unsigned Short /10. Range = 0...6553.5
A3: Unsigned Short /100. Range = 0...655.35
Conversion: float*x = unsigned integer
Unsigned integer/x = float
Or cast:
float value to read= ((float) (value))/x;
unsigned short value to write= (unsigned short) (value*x)
Register Configuration B
15 14 13 12
B1: Signed Short. Range -32768...+32767
B2: Signed Short /10. Range -3276.8...+3276.7
B3: Signed Short /100. Range -327.68...+327.67
Most languages will cast from one type to another
Values to write into register manually:
if value is a negative number: (value*x) +65536
if value is 0 or a positive number: value*x
e.g. for type B3
(-5.39*100) + 65536 = 64997
(2.01*100) = 201
Or Cast:
(unsigned short) (value*x)
