Tutorial 6

Postby helge » Wed Nov 12, 2003 6:31 am

I am using the tutorial 6 (salvo pro) and I have tried to extend it with a few more tasks. However it doesn't seem to work with more tasks than 3 for some reason. I have updated the salvocfg file so that OSTASKS is at the right amount. I am using salvo with MPLAB ICD v6.3. If I run it I get a stack overflow message. Why?

Did you change the library from sfpxx.lib to slpxx.lib, and set OSLIBRARY_TYPE accordingly (to OSL) in salvocfg.h?

The freeware libraries will reject attempts to create and run more than 3 tasks, etc. If you check the return codes for OSCreateTask() you'll see that it is returning a non-zero code (OSERR).

As for the stack overflow, that's likely to be an improperly configured MPLAB project (e.g. are the compiler and linker aware that you're compiling for MPLAB-ICD).
