This project is to provide a simple application to control the AVR butterfly hardware to time the interval between pulses duration 50 milleseconds on a port pin and output a voltage on the AVR D to A from 0 to 100% proportional to the inverse of the time interval. According to the formula A/D register (Vout%) = (1.5/(Av Flash frequency Hz))*100). If result overflows then set to FF. Where the flash frequency is averaged over the last n pulses.(n configurable but hard-coded).
If Av Flash frequen…
