Header bug?

blittled

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);
}

propeller-elf-gcc -o pulse.o -c pulse.c
propeller-elf-gcc -o pulse.elf pulse.o main.c

Ups, I see David was faster

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