Andy Neil said:
Rather than just randomly change delays, have you looked at what's actually happening, using an oscilloscoscope?

Jan Waclawek said:
it should be enough to have a look at the generated assembler for the delay.

I think you should do both:

  • Check the assembler to see that the compiler's giving what you expected;
  • Use the scope to confirm that this does actually give the output that you expected (eg, you haven't mis-counted your instruction cycles).
