Re: Interrupts - ISRRX Glitches

I know it's not really offering anything new, but I must endorse what Jerry has said. I have many commercial programs running with interrupts without any problems - because I keep anything in an ISR to the bare minimum. When using an 8 bit PIC MCU you need to think about the problem differently from...

Re: compiler expectations for bank select register?

It needs to be the same - the compiler does not track ANY user changes

Re: compiler expectations for bank select register?

If some user code modifies BSR, the user code is responsible for restoring it.

Re: issue with comparing structures

I would say that the compiler should not really be allowing this comparison, as there is no internal mechanism for making the comparison (at least, not as far as a remember). There is a mechanism for strings, which are very similar in terms of comparing a block of data but not for structures. My onl...

Re: Swordfish Simulator?

I think Labcenter have gone down the route that everything should be centered around their IDE, which means they have pulled support for a standalone simulator (ISIS). I think the only viable future is source level debugging, as Jerry previously mentioned. This thread may also be of use: http://sfco...

$long-hex-filename$ => pass fully qualified hex filename to loader
-dPIC$target-device$ => PIC device
-iprogram => start programming, don't show loader interface
