2byte Unicode in KDS3.2 /wchar_t

Hi,

I want to use 2 byte Unicode in my KDS3.2 / SDK 2.0project .

I have found this : Unicode support in KDS3.0?

and I set my compile parametr for GCC (Properties / C/C++ Build / Cross ARM C Compiler / Miscellanous / other compiler flags): -fshort-wchar

It can generate 2 byte unicode strings.

Is it possible to use functions from wchar.h as

swprintf, (wchar_t *__restrict, size_t, const wchar_t *__restrict, ...); ?

When I try to use

wchar_t buf[20];

swprintf(buf, 20, L"%ls", L"XAHOJ123456");

the buffer buf[20] is set as 2byte,

the functin use buf as 4byte , the buf is overloaded in the swprintf()

and a hard fault error ocure.

Have I use other library, or copile the library somehow?

Thank You,

Jaroslav

Hi,

from what I know KDS doesn't have other replacement function for swprintf.

I think the only "fix" is to use 4bytes buf for swprintf.

Have a great day,

Hi Jennie,

I am afraid that you are right.

My problem is, that I need to convert existig CW project to KDS.

The project has a lot of code included 2byte strings in Flash, od SDHC card and

on the "other side" of USB. It is not simple to convert all of them.

Best regards

Jaroslav
