Hi Rob, I look forward to the final version, thank you for your effort. BTW the current function is not used, the calculation and calibrations of the real resistance I do in the main program. By max current and dividing by 0.1 you need a dword in the present function. I don't know how to handle the sign bit when there is negative current, I dont use it at the moment , others will do maybe.
kind regards Bill. On Monday, August 18, 2025 at 1:00:08 PM UTC+2 Rob CJ wrote: > Hi Bill, > > I agree with you not to use floats and do the calculation in the main > program.
