Target not created
Unfortunately i didn’t get much help in any forums and after two long days. It took me two days to figure it out. I had a working Keil v4 STM32 project and decided to cross reference it. I did verify all the details and everything was same except i found a define in the C/C++ compiler tab which said USE_STDPERIPH_DRIVER , When i included this define in my project, Voila! everything was right, 0 errors, 0 warnings.
Solution to assert_param declared implicitly error in Keil :
1) Go to the menu and click on the tab Flash->Configure Flash Tools
2) Click on the C/C++ tab
3) Find the Define field under Preprocessor Symbols and enter USE_STDPERIPH_DRIVER
4) Click OK and recompile your project, your problem should be fixed now.
Alternatively you can also fix the problem and define USE_STDPERIPH_DRIVER by removing the comment on line no 125 of stm32f0xx.h file.
Hope it helps someone 🙂
