Seemingly Simple Syntax Question

[Jerry Finsen]

The following snippet fails to compile the call to Test2: "Bad expression syntax:.

What am I missing?

include <16F877.h>
//********************************
// Prototypes
void Test1(Char String);
void Test2(int x, Char String);

//********************************
// Main
void main() {

Test1( "Hello World");
Test2(1, "Hello World");

}

//********************************
// Subroutines

void Test1(Char String)
{
return;
}

void Test2(int x, char String)
{
return;
}

When you pass a string you are passing a char pointer.
I modified the code it should work now...

CCS doesn't permit pointers to constant strings.
You have to copy the string to a ram buffer first.
Example:

<PRE>
#include "16F877.h"
#fuses HS, NOWDT,NOPROTECT,PUT,BROWNOUT, NOLVP
#use Delay(clock=8000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
<BR>
void Test1(char* String);
//===============================
void main()
{
char temp[20];
<BR>
strcpy(temp, "Hello World");
<BR>
Test1(temp);
<BR>
while(1);
<BR>
}
<BR>
//===============================
void Test1(char* String)
{
printf("\%s", String);
}
</PRE>

I copied your code into the IDE and tried to compile ... same error. Mysterious that it doesn't complain about the call to Test1.

Using 3.146 of the compiler.
