comment Programming USB OTG PIC32 through USB in MPLAB
You need to specify more details? Which PIC32? MPLAB 8 or X? Are you talking about a development kit or 'just a part' without any pre-programmed firmware? AFAIK Microchip does not blow any special firmware into their parts unless you pay them extra for it and provide the software yourself (they spin a custom part/order number for you for this activity).

Thanks for the downvote, by the way.

comment How do I simulate a dc-dc boost converter in LTspice?
Look up '3 terminal PWM switch model' on your search engine of choice. It abstracts out the MOSFET, PWM and diode into a single block and allows you to just focus on the dynamics of the converter. You can find these for LTspice if you look around (check Christophe Basso's webpage).

You could also post your own answer with these details. Considering that this question is more than 4 years old though, I doubt that it will get any attention from OP.

comment Why to disconnect the negative/ground terminal, not positive?
@Sempie It is generally not recommended to accept an answer immediately as it discourages others from contributing to the conversation - others will be discouraged from answering since the 'bonus' for acceptance has already been awarded. Waiting 24 hours or so is a good practice.

Please use the integrated MathML for formulae, not embedded images.

comment Unwanted oscillations and distortions in buck converter
Um, why are you using an LM393 instead of a proper PWM controller? And why would you arbitrarily change the inductor size, knowing how crucial it is in the overall operation of the buck? If you're just tinkering to learn about bucks, may I suggest that you grab a PWM switch model from this site and then experiment with frequency, inductance and capacitance? The PWM switch model abstracts out the messy bits of the control and allows you to understand the dynamics of how the converter works without designing a full-blown controller.

comment Cannot debug project using “MPLAB X IDE” on “PIC32 Bluetooth Audio Development Kit” with “PICkit 3 In-Circuit Debugger”
+1. Incorrect debug port settings in your config registers does exactly what you've noticed - you can program the part just fine but cannot debug it.

comment Possible wrong use of TVS diodes?
This is a good start for a question, but we need more information: a more complete schematic and a section of the PCB artwork would help. I cannot consider GND and DGND without knowing how they relate to each other in the circuit, for example. That being said, "properly connected" TVSs would not cause issues as you've described: either the PCB footprint is incorrect or there's something weird going on with your circuit that we cannot see (yet). I'll share an upvote as incentive for you to better define your problem.

comment Serial Port not found by MATLAB to communicate with Arduino
Probably a better fit for SuperUser since this is a PC hardware/software question.
