Frequency & period counter , milliHz counter (1/period) , rpm counter (tachometer)
Uses 80c52 , 12MHz crystal , 16*2 alfhanumeric LCD display , 1 led , 2 pushbutton switch

frequency range 1Hz - 400KHz
period range 100uS - 8Sec.
out of this range the counter DO NOT WORKS
for good precision crystal oscillator calibration is suggested.
attached counter.zip (Multicounter.bas)
