    [PIC]Closed: Re: Question About Crc8 Picbasic Implementation

    You need to review the PICBASIC manual. HEX2 means two hex digit formatting.

    In my view, the original question hasn't much to do with CRC algorithm. It's more general how to implement a specific...

    Closed: Re: Current Density PCB track

    No. Small trace is dissipating most heat by lateral conduction, thus higher specific rating. Large plane must dissipate all heat vertically. By the way, radiation plays a minor role in heat...

    Always a good idea to read the manual completely. Review page 13.

    [PIC]Closed: Re: Question About Crc8 Picbasic Implementation

    The CRC algorithm as functional as such, question is how it's used in the application, if CRC is initialized correctly, how you feed CRC_IN. This can't be seen from your code snippet.

    As the question is posted in PCB Layout rather than RF or Analog Design section, I fear it's really unclear what "De Q'ing" resistor means for you. Please give a typical example.

    How do you know that specifically the HS driver is "blowing"? Sure that the MOSFETs are still healthy? There are several possible circuit issues, too large bootstrap series resistor is one of it.
  20. Closed: Re: Measuring voltage drop across a diode in a switching circuit

    That's voltage with zero output current - irrelevant.

    Instead of assuming an idealized current independent 0.7V voltage drop, you want to look for the actual diode I/V characteristic.
