Thanks for your reply.

I just put a "#define TMR0 TMR0L" below the "#if defined(USE_INTERRUPTS)" to fix the problem.

Although I suppose it should be in an #if defined(SYSE)....

Compiles fine now.

Yes.

Tu5 (and tu6) use interrupts and isr.c in order to implement delays via Salvo' timer services.

TMR0 is referenced in the ISR (in isr.c) and in Init() (to initialize the timer).

IIRC, thre is an issue surround the use of the term "TMR0" (as opposed to TMR0L and TMR0H) with the MPLAB-C18 compiler.

The best way to solve this in your case is to modify the Init() macro and the ISR so that you end up with an ISR that calls OSTimer() at a 10Hz rate.

The problem in your Build Results is simply that MPLAB-C18 doesn't know what TMR0 is -- it only knows about TMR0L and TMR0H.

Below is how tutorial 5 fails to compile for me. I have done the '$BINDIR-browse...' to get TU1-4 built, but when I use \salvo\tut\tu5\syse\tu5lite.mcp, tu5 will not build.

Any idea on why this won't build?
