I need to convert the resistance of a thermistor to a temperature
. This uses a natural log function. Since I'm not concerned about speed, I want to use a SPIN library to do the natural log. (integer fixed point or floating point is fine) I'd like to avoid having to make a thread-safe version of F32.
Hopefully someone has a version of "FloatMath.spin" upgraded to use the ROM log table, or a version of Chip's Cordic code
adjusted to do LOG functions? (don't want to re-invent the wheel.) Alternatively, if someone has cubic-interpolation code for spin, I could live with a look up table.
