Help converting small PicBasic program to MP LAB

[HenrikOlsson]

What range of frequencies are you aiming to generate. I see from your SOUND statements that it would equal notes 50 to 113 but I don't know what that translates to in actual frequency (and are those numbers critical?

Like Art says, all the SOUND command is doing is toggling a pin. You can do that too and you make the ADC do the conversion while waiting to flip the pin. Something like this perhaps (not tested):

SomeValue CON 250
SomeConstant CON 4

Main:
IF Trigger THEN
  SPK = 1   ' Set pin high

  GO_DONE = 1
  WHILE GO_DONE : WEND   ' AD conversion will always take the same amount of time
  PAUSEUS SomeValue + (ADRES * SomeConstant)

  SPK = 0

  GO_DONE = 1
  WHILE GO_DONE : WEND   ' AD conversion will always take the same amount of time
  PAUSEUS SomeValue + (ADRES * SomeConstant)
ENDIF
Goto Main
