I don't see the defines for KEY_A..KEY_Q. Assuming they ae correct, I bet the index you pass into buildReport() isn't in the range 0..17. I dont use letters, as you see in recieving routine i only accept numbers and CR. And i think there is nowhere to change them during programm flow, so i dont hav...

But T0 is just 8bit timer. It cant contain large values, right?
And to setup T1 i must use

Code: Select all

TCCR1B=0x06;

?
And then, read counted pulses using

Code: Select all

TIFR1

?

AVR-USB frequency meter

Is there way to make usb frequency meter like EasyLogger? I have done it with rs232 and it counts this way: Fast timer counts ticks of itself between signal pulses, that way measurement done very quickly. Can it be done on single chip like EasyLogger? i mean is there enought resources left for this ...
