hello:

Actually test the execution time of each statement so slowly. My sys clk is 200MHZ.

for example:

  void delay_rotor(UInt8 cycles)
  {
      while(cycles--);
    }

when cycles=1, this code need about 5us.

I don't know why!

 thanks !

Hello,

How do you measure execution time? Are you tracing instructions? or with scope or some timer?

I am not able to tell you where is the issue from your description. Could you be more specific please?

regards,

Peter
