    A huge mistake, I've seen a lot of code where clearly the author thought that just adding "synchronized" would have solved any concurrency issue. And no one even talks about how sy…

    Sadly it's not maintained anymore and even the intellijidea-derived decompilers are better nowadays (used to be horrible until a few years ago). In addition to the limitation to cl…

    As someone that used it for years with the same problems he describes... spot on analysis, the library does too much for you (e.g. reconnection handling) and handling even basic re…

    Just FYI, since I've implemented something similar in Swift, using the PWM you would have had to implement more or less the same algorithm, i.e. changing the duty cycle of an high …
