WHAT CHANGES TO MAKE IN CASE OF STM32 BLUE PILL?

Dear Moty, Thank you for an interesting project! When I used your C-code, it found that measurement of frequency is possible up to 6 MHz. But I did find small jitter of 1 Hz times, which causes spikes of measurement results (downwards on the order of 10 ... 20 Hz of reading). Probably this jitter causes the increment of standard deviation of the frequency measurements to be on the order of 10E-5. Moty, could you please check the C-code and try to eliminate the jitter? According to my estimates, after eliminating the jitter, it is possible to reduce the standard deviation to 1E-6 and we may use Arduino it like an inexpensive alternative to a commercial frequency meter. Regards, Arthur Minigalin
