Closest useful functionality may be strtoul(3), which is present (I haven't
personally tested it).

 Hi,

 I am trying to port some software to msp430-gcc. I think the code was
 originally written for IAR (not sure). The original author used sscanf
 to extract unsigned short ints (%hu) from a string buffer. Is there
 an equivalent libc or other function call in msp430-gcc.

 regards
 b thomas

I have, and it works.
However, I did encounter breakage with one of the newer compiler builds,
apparently because it uses register variables. As a workaround, I made a
copy with normal variable declarations, which works fine.

hi michiel,

your mention of broken register variables caught my eye.

can you, or peter, please clarify?

thanks,

If you can duplicate that with mspgcc4 please let me know or file a ticket
on that project and I'll see it gets fixed.

Re: [Mspgcc-users] sscanf for msp430-gcc

2010-04-19 Thread Michiel Konstapel 
I was using strtoul on a '2418 and it would continually reset. I dug up
the source and compared it to that of atoi, which did work. The former
used register variables:

unsigned long
strtoul(nptr, endptr, base)
const char *nptr;
char **endptr;
register int base;
{
register const char *s = nptr;
register unsigned long acc;
register unsigned char c;


I made a copy, removed the register modifiers and well, that seemed to
work. This was with an older build of the MSP430X compiler. I figured
I'd quickly recheck, and now it seems it doesn't reboot, but instead
reports the wrong values. I'm afraid I don't have time to look into that
at the moment, though.

Regards,
Michiel

This is on 3.2.3 (OSHAN); I'll see if I can whip up a test with 4.4.3
later.
