My program like it:

pastedImage_1.png

When I build project,it has a error:undefined reference to "Convert_Data".

But,I defined it at previous row.

Even if defined as global variable.

It still has same error.

Hi, 

thanks for sharing project. Convert_Data function is not implemented in your project. It is only declared - that's why linker can't find it.

Hi,

where is Convert_Data() function defined? You can try declare it by this way (if it is in different object file): 

extern uint32 Convert_Data(uint8* data);

Here.

Although I have not seen this usage.

My program is modified using the official sample program.

Bold guess,there are some problems with the compiler.

My program file:
