This is a childlike reckon . The Frequency is impermanent through an op-amp to abbey it in a square indicate . The ouput of the op-amp is feeding the 3*8 bits counter (24 bits) who can accumulate at a maximum of 16777216 poll . The maximum frequency you can criterion without changing the point base of one end is 16.777216 Mhz. The ATMega8 hold 3 functions: enable the counter gate at each end, construe his value and declare it on the LCD.
