WebSep 27, 2024 · 3. It's a bad idea to define variables in an include-file. The reason is that you won't be able to include that include-file in more than one c-file. If you do, you'll get the errors that you have now. So the code you have posted shal be moved to a c-file and in the include-file you just put: extern volatile SYSCFG_t* mysyscfg; extern volatile ...
