If duty_ns is large enough multiplying it by 255 overflows and results wrong duty cycle value being programmed. For example with 10ms duty when period is 20ms (50%) we get 255 * 10000000 / 20000000 = -87 because 255 * 10000000 overlows int. Whereas correct value should be 255 * 10000000 / 20000000 = 127 Fix this by using unsigned long long as type for on_time_div and changing integer literals to use proper type annotation.
