UPDATE
THe previous windlogger was released in the final version (some minor bugfixes, but now it is complete).
New windlogger:
This time i use the PIC18F2680 64Byte microcontroller for more memory and code space. New features:
-16Bit trigonometry (with some functions working with 32 bit inputs, such as SQRT and ATAN2) for accurate average wind direction calculation -10Bit windvane based on the AS5040, PWM output (second order low pass filtered) read by the PIC18F... onboard ADC, indicated both in the angular form and text form (eg NE, SW, E, etc) -Logging minimum wind speed and standard deviation of the samples within the samplig period in addition to wind average and wind maximum -Supports transfer function in the Y=M * X + Q format (the previous version worked only with Y = M * X, giving some errors at low wind speeds), future version may support polynomials(?) -Support all the characteristics of the old program.
