Hi Goorman,

You are right. Good eye.
Of course it should be
Frequency = Counter0_ovf_count * 256
I did not test it in real.

Why do you not use timer1 for counting pulses?

Not bad for a beginner.

There is some inaccuracy in measuring at high frequencies.It is because you count pulses not for 1 sec, but for 122*0.8192 = 999,424 ms.
So your result is 1/1000 less than ...

Attiny85 has not registers UBRR, UCR.

You can use the software UART.
See the command OPEN in Bascom-help.

You can use Timer0 in CTC mode.
In this mode the timer counts only to OCR0A value, not to 255, and then clears to 0.
When it reaches OCR0A value, the interrupt COMPARE0A occures (if enabled).
