High Resolution PWM control about protocol HOT 5 OPEN

I'm not sure I understand your requirement. Do you need a higher resolution of the duty cycle (e.g 16 bits) or a way to set the frequency (for which there's currently no option in the protocol)?

Yap, I need a high-resolution duty cycle and the current protocol does not directly support it. (But it is not a problem, can be easily modified to achieve that )

That's not exactly correct. To use more than 14 bits for the PWM resolution, you can use the EXTENDED_ANALOG message (described here) instead of the fixed-length ANALOG_MESSAGE. To take advantage of this, you need a board that supports the higher resolution, of course.

I used an Arduino MEGA2560 and I can change some registers to let it support higher resolution. After that, it becomes a little bit different since I cannot directly call Arduino analogWrite() method.

analogWrite() takes an int (16 bit) as the second argument, so this should actually work. Have you created a test sketch that uses analogWriteResolution and analogWrite to test how this works with 16 bits?
