I'm working on a FE-C profile for a bicycle trainer. For page 17 of general data, byte 3 stores cycle length which for a trainer is wheel circumference in meters:

3 Cycle length 1 Byte Length of one ‘cycle’ (section 7.5.3.1). 0xFF indicates invalid 0.01 meters 0 - 2.54 m

I'm a newbie, it is late. I am tired and need help figuring out how to store a decimal value into the 1 byte field.

everything I've done previously requires 4 bytes to store a float

How do the pros do it in 1 byte?      

Is it as easy as 2.54 equal 254?      

Hi Ross,

Yes, it is that easy. The Units column tells you how to interpret the value field. For cycle length, the units are described as 0.01 meters. This means that if a value of 1 is stored, it should be interpreted as 0.01 meters. And therefore the range of the field is 0 - 2.54 m.
