Firmata and PWM-pins problems

[antongit]

Hello,

I have an issue with those PWM / Analog pins (like the pin10).
If I change the "LattePandaFirmataDemo" so that I'm controlling PWM on pin 10 like this:

arduino.pinMode(10, Arduino.PWM);
arduino.analogWrite(10, bar.Value);

my LED lights up ONLY when the slider is on the right and I'm sending 255, nothing happens in-between. The app gets very unresponsive as well.

This issue doesn't appear if I use pin11 which is not overloaded by any Analog pin.
