Weird issue with Lab X1

[Demon]

The ICS502 LOCO™ is the most cost effective
way to generate a high quality, high frequency
clock output and a reference from a low frequency
crystal or clock input. The name LOCO stands for
LOw Cost Oscillator, as it is designed to replace
crystal oscillators in most electronic systems. Using
Phase-Locked-Loop (PLL) techniques, the device
uses a standard fundamental mode, inexpensive
crystal to produce output clocks up to 160 MHz.
Stored in the chip’s ROM is the ability to generate
6 different multiplication factors, allowing one
chip to output many common frequencies...


It's used to generate the clock, the jumpers are set to 4, and it works fine, until I replug.

I would say it works fine, or else it wouldn't work at all when I program.

I found these:

E:\Mecanique\MCSP\MPASM\P16f877.inc

E:\Pic BASIC Pro 2.46\16F877.INC

E:\Pic BASIC Pro 2.46\M16F87X.INC <---- I would think I want to include this one.


So I tried this:


ASM
LIST
include 'M16F87x.INC' ; PM header
device pic16F877, xt_osc, wdt_on, pwrt_on, lvp_off, protect_off
XALL
NOLIST
ENDASM


And I get an error it cannot open file, include 'M16F87x.INC' not found.

In MicroCode Studio Plus, under tabs VIEW, EDITOR OPTIONS, the Default Source Folder points here:
E:\Pic BASIC Pro 2.46

I would have thought it would pick up the file that way.


EDIT: So I copied M16F87X.INC where I have my PIC program source, usually compilers look in their source folder first, but it can't find it anyways. It looks like it wants to find INCLUDE files somewhere specific, I just don't see any way to tell MCSP.

Look in you PBP directory for 16F877.inc. That file is already included there, you do not need to worry about it.

In my opinion if you are getting back into this for the long term give up on PM and use MPASM. You will have to at some point, might as well be now.

Yeah, I looked at the generated files and opened up LST, very interesting.

I noticed it was already picking up P16F877.INC.

Then it picked up PBPPIC14.LIB.

And then further down it tried to open the include I provided. So it seems as if everything is in there now. Except it uses this for the switches:

__config _XT_OSC & _WDT_ON & _PWRTE_ON & _LVP_OFF & _CP_OFF

And I'm wondering if this is what I have to set properly, and how.


EDIT: And yes, I am pointing to MPASM in MicroCode Studio Plus.

[mackrackit]

Yup, fuse are very important

You can modify the *.inc file or set them in code.

That's what I'm trying to do, thanks.

I don't like changing the include, in case I have different needs in another program.

So I tried this:

@ __config _CP_OFF & _DEBUG_OFF & _WRT_ENABLE_ON & _CPD_ON & _LVP_ON & _BODEN_ON & _PWRTE_ON & _WDT_ON & _XT_OSC


But it's doing the same thing, the speed goes crazy when I reconnect.

Not sure if I set the switches properly though.

EDIT: I list all switches, that way I can easily see what is available without going back to datasheet, even if I use default values.

[mackrackit]

Might want to turn LVP off, I do not think you are using it.

I keep going back to hat fancy OSC thing. The 877 is pretty straight forward. Has to be the OSC acting up to cause a change in speed. Power cycling causing a clitch? And somehow the programmer is resetting it?
