START
Launch IDEA click Project, Right click path working directory workspace window, select Update select your path Click Tools menu configure them:
Compiler: memory model, debug information, listing file. Linker: ouput file (.st7), command file (.lkf) Builder: user utility (cvdwarf appli.st7 appli.elf)
edit file: right click file select edit (double click soon available)
START
Click Build command build application there some errors, dedicated window will appear (double click errors correct them) Otherwise errors message will appear below source window debugging, click debug icon launch configured debugger (ZAP STVD7)
