NAME
       pwmtestperf - Applies a simple test pattern to a PWM output


SYNOPSIS
       pwmtestperf [-c chipno] [-p pwmno] [-P periodlength] [-S step] [-v]


Description
       pwmtestperf  is  a  debug tool to test repeated setting of the output waveform emitted by a PWM.  The PWM
       that is used by this test is specified by chipno and pwmno.

       The fixed period is specified by periodlength and the duty length is increased in each steps by  step  up
       from 0 to periodlength.  (If step is negative, it decreases from periodlength to 0.


Options
       -c chipno
              Each  PWM chip has an identifying chip number.  pwmtestperf configures a PWM line provided by chip
              number chipno.  chipno defaults to 0.

       -p pwmno
              Each PWM chip provides a number of PWM outputs.  pwmtestperf configures the pwmnoth PWM output  of
              the selected chip.  pwmno defaults to 0.

       -P periodlength
              periodlength in nanoseconds defines the length of the periods of the waveform to be set.

       -S step
              in  nanoseconds  defines  the  step  the  duty  length is increased in each step. (Or decreased if
              negative.)

       -v     Emit some information during runtime.
