You do not have enough code space to use scanf()...

Hi ,
I have assigned 64k of local memory.
Is there an alternative to this problem im facing.

I want to be able to read intergers from the hyper terminal.

Thanks

Hi ,
I have assigned 64k of local memory.
Is there an alternative to this problem im facing.

Allocate more memory or try iscanf, which is an integer only version
of scanf, that should require less code space. (There should be
iprintf too).

Cheers,
Jon

scanf and printf are monsters - they do everything but there is a huge
amount of code.
also, the Microblaze code is not very compact.

I needed to print and read some integers, so I just used simple functions
that do just that. It should not take more than a couple hundred bytes...
Something like this 1 minute example not guaranteed to work at all

int fake_atoi( const char *c )
{
int n = 0;
while( isdigit( *c ))
n = n*10 + (*c++ - '0');
return n;
}

Hi,
Didnt find iscanf in the library. very reluctatntly chose reading
in the number a digit at a time using
XUartLite_RecvByte into an array and then converted that array to a
number...

hope it holds well during the demo

Thanks guys
