Instant Interrupts - Revisited

[Homerclese]

Hello,

I tried a cut and paste of your code and got a whole new set of errors. The only code differences I could find were the ones at the top for outputting to a LCD display. The include files all exist in my usual PBP folder. I'm using Microcode Studio version 2.2.1.1 with Pic Basic Pro 2.40.


Thanks John

did you get...

If so, make sure you have selected MPASM in the View>> Compile And Program option >>> Assembler

EDIT

Pic Basic Pro 2.40.

I don't know if it could be the problem... The current version is now 2.47.

Gettin' better!

MPASM box was not checked. I didn't know it existed. No errors on compile now, however it can not find the .HEX file for programming. I did a system search and there is no .HEX file generated after compile. There are .HXH and .HXL files.

Is your result box a screen capture?

Thanks again

It happen because you probably have selected INH8XS file format under the MPASM check box. use INHX8M instead.

Is your result box a screen capture?

Yes indeed, CTRL + PrintScr, then you paste it in Paint or whatever else to edit it.

Good, That worked. However, when I add a line to the top of the program as simple as :
TRISA = %00000000
AlarmOUT VAR PORTA.0

I get

Error[113 cbp\pbpic14.lib 1588 : Symbol not previously defined (port A)
Error[113 cbp\pbpic14.lib 1612 : Symbol not previously defined (port A)
Error[113 cbp\pbpic14.lib 1619 : Symbol not previously defined (port A)

.........Etc.


Also, going back to the previously working "elapsed timer demo" and using the MPASM settings I get the same type of errors there if I try to add a port reference.

I can get the result box into Photoshop but can't get the edited image to paste into the forum.


Thanks

<table><td></td><td>It really drives me nuts when it work here but not elsewhere. Ok then just copy/paste your code here and place it between code bracket. you just need to type...

---paste your code here---
[/code]

to edit your screen capture, use Windows paint. If you don't find it, click on Start> run then type mspaint. then save it to a .jpg file</td></table>

You said you were using the 16F877. Are you sure it's not the 16F877A?
'cause if it is, you need to upgrade your PBP. You said you've got PBP 2.40. The 16F877A isn't supported until PBP 2.42

[Homerclese]

"Not previously defined" error was caused by having PortA instead of PORTA. It's 4AM and I think MPASM is the cause of some strange chip behavior. Only when I uncheck MPASM do I get back to a working 16F877 chip. I patched pic basic Pro to 2.40 but any attempts to go higher are met with "unknown version" errors. I'll hit it again tommorrooowww....
