16F88 internal clock configuration

[mister_e]

Post your new code here to see wha can it should be.

[Tom Gonser]

Here it is..

It won't do much unless you have this particular type of GPS that outputs the wierd data.. I captured some as a text file(which it is not).

Attached is a zip file with

1. shorter program files (Less the LST - it was too big)
2. the 16F88 include file I use

probably i'm getting older and need to sleep after only 22 hours awake but, i can't see why it's not working. I really suspect an hardware problem now. 0.1 uF ceramic Capacitor close to the PIC.

i didn't get any compile error with the select case stuff.

did you install the PBP patch for the F88???

Here's the patch

about the calculation what about if you skip the hexa to decimal and do like Bruce propose few post ago!!!

[Tom Gonser]

Thanks.. I'll try the patch and see what happens. Is the CAP from Gnd - + close to the V+ pin? I have nothing there.

What post about skipping the Hex conv? I don't see that post in this thread.

Odd.. that patch does not work for me. It says the 16F88 file is an "unknown version"...

[mister_e]

hhhhhhhhhhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa So you don't have the PBP 2.45!!!! probably the main cause of all your problem. OR if you have V2.45, remove it, reboot your system in 'safe mode', reinstall everything, and after that install the patch. everything should be done in a shell environement.

start>> all programs>> accesories>> command prompt

AND yes the capacitor must be place between 5 volt and ground as close as you can to the PIC.

i thought it was on this post... sorry

there you go

Hmmm.. Reinstalling PBP is just copying files to a folder I thought. I think I need to do this, but am not sure exactly how to 'deinstall'. PBP does not show up in WinXP as a program that has a de-installer. I can move them out of a folder, restart, then put them back, but I don't see what that would do.

Also, I think the 16F88.bas file is corrupt because the installer tries to update it, but says it fails because of an unknown version of that 16f88.bas.... This is probably the reason for the odd behaviour.

I'll ping MELABS..

Thanks for all your help!

Thanks folks!! The pesky (and cool) 16F88 gave up the ghost, and is computing math right!! I re-installed PBP, updated the 16F88.INC files, and reduced program space to 3000 from 4200. I DID have to struggle with the _CONFIG settings a bit, finally dupmping the .INC files in favor of putting it in the code after the @...

[but] The ONLY thing that remains is an odd thing... My 'Onetime' routine does not appear to 'take'... I WANT it to go the the routine 'Onetime', and output data on the various serouts.. sort of a 'welcome' for 5 seconds.. What they DO is 'flash' super fast, and then disappear. Then the main program loop starts and things work fine..

This is the LAST issue with this port! Is the fact I was running at 4mhz on the other unit an issue? I have the following OSC flags:

DEFINE OSC 8
OSCCON=%01111000 '8 Mhz
CMCON = 7 'turn comparators off
ANSEL = 0 'All digital


A section of the program follows:

....

Init:

PORTA = %00000 'Initialize PortA to all zeros - all output
TRISA = %00000 'All port A output

PORTB = %00000010 'Initialize PortB
TRISB = %00000010 'Port 2 input
