CubeIDE , Keil have different requirement for Serial Wire Viewer
- CubeIDE :
> _write() redefinition is required
//in CubeIDE, redefinition of _write is ncessary
int _write(int file, char *ptr, int len)
{
for(int i = 0; i < len; i++)
{
ITM_SendChar(*ptr++);
}
return len;
}
Using Serial Wire Trace with CubeIDE (aka a new level of debugging) – EmbedBlog
I’ve been developing for STM32’s for a couple of years now, and I did a lot of different projects – from large powersupplies to small headlamps – but on 95 % of them, I used two connectors: SWD (Serial Wire Debug), used to program and debug the chi

- Keil :
> fputc() redefinition is required
int fputc(int ch, FILE *f)
{
ITM_SendChar(ch);
return(ch);
