DT Instant Interrupt counting

[jderson]

Thanks Joe. I commented out the offending line, and also the "T" line in the "Reenter" program. It now tries to assemble, but comes back saying "unknown processor 16f689". I removed the line at the top of my program about the WDT, but it still does the same thing. How does it know I'm using a 16f689?

Because you selected that processor in Microcode Studio, up at the top. When it compiles it includes the appropriate files for that processor. Oh and this too @ DEVICE pic16f689,wdt_off,
Note: you must use the MPASM assembler with Darrel's includes.

I removed the @DEVICE line, and I have MPASM enabled. It is MPASM that is generating the errors. I think the problem has to do with where all of the various components are located, relative to one another. (MPASM can't find the P16F689.INC file) I'm still reading.

Try this for your config statement:
@__CONFIG _HS_OSC & _WDT_OFF & _PWRTE_ON & _LVP_OFF & _BODEN_OFF

Thanks for trying Joe, but that didn't do it. I think there's something fundamentally wrong, as the compiler doesn't know about 16f689.

I don.t know what version you are using, look into your PBP directory and see if you have a file16F689.inc, also see if the code compiles with a similar chip. OK here is the data sheet:http://ww1.microchip.com/downloads/e...Doc/41262B.pdf

Yes, the file is there. And I already have 2 copies of the data sheet, thank you!
Here are the first three error messages:

Error [132]c:\pbp\16f689.inc 20: Unknown processor (16f689)
Message [301] c:\progra~1\mecani~\mcs\p16f689.inc 32: MESSAGE: (Processor header file mismatch. Verify selected processor.)
Error [131]c:\pbp\16f689.inc 22: Processor type is undefined.

Many more errors.
