According to RKit-STM8 release note scanf and sscanf are now available for the STM8. Is that true? We are going to update our software because of sscanf support.

Thaks for reply. We have updated our software to enterprise. Then I try to use sscanf but I got errors:

LINK/LOCATE RUN COMPLETE, 3 ERRORS FOUND.

This is code I have used:

char _time [] = "15:15:00";
int hour, minute, second;
sscanf(_time, "%02d:%02d:%02d", &hour, &minute, &second);

Can You give me some points how to use sscanf?

Hello,

sscanf is using the getchar protocol,

FULLB_SCI, USART_DR and USART_SR are objects which are managed by the SCI name (ride7-> local settings -> Advanced ST7/STm8 options -> Processor).
Could you provide us the name of the STM8 device you are using and the SCI name associated to this one?

You can also try, as workaround, to add to your project :

char getchar () {}

Best regards,
