I'm sorry, it still does not work .
LED always light, (no flashing)
always have output pulse signal, I measured is 460ms.
460uS is too low, it should never produce such a short output pulse. Perhaps your clock frequency is wrong?
I harvested an ATmega8 from an old ESC, but I couldn't think of an easy way to hook it up, so I bought a DIP version which I can plug into my breadboard. V0.5 firmware works fine with it, using a 16MHz ceramic resonator and fuse settings SUT1:0=10 CKSEL3:0=1110.
I did find a small bug that caused the LED to light with full brightness above 0% PWM input (it should only go to full brightness at 100% PWM). Here is V0.6, which fixes this bug.
