  I am building a library and have the following code
  

  void PULSE(int pin, uint32_t duration)
  {
      int mask = 1 << pin;
  
      DIRA |= mask;
  
      OUTA |= mask;
      DELAY(duration);
      OUTA &= ~mask;
  }
  
  void DELAY(uint32_t duration)
  {
      uint32_t time;
     
      time = CNT;
      waitcnt(duration + time);
  }
  

  
  header file

  void PULSE(int pin, uint32_t duration);
  
  void DELAY(uint32_t duration);
  

  
  This produces the error "unknown type name uint32_t" error when compiling with a file using #include in the header file for both functions, should this happen?

  
  Did you include stdint.h? That is where uint32_t is defined.
  

  #include <stdint.h>

  Try:
  

  #include <stdint.h>
  
  void PULSE(int pin, uint32_t duration);
  
  void DELAY(uint32_t duration);
  

  #include "pulse.h"
  
  void main ()
  {
      for(;;)
      {
          PULSE(0,10000);
          DELAY(20000);
      }
  }
  

  #include <propeller.h>
  #include "pulse.h"
  
  void PULSE(int pin, uint32_t duration)
  {
      int mask = 1 << pin;
  
      DIRA |= mask;
  
      OUTA |= mask;
      DELAY(duration);
      OUTA &= ~mask;
  }
  
  void DELAY(uint32_t duration)
  {
      uint32_t time;
     
      time = CNT;
      waitcnt(duration + time);
  }

  Ups, I see David was faster

  Including the stdint.h did the trick! I'll have to learn what is in the libraries. Thanks!
