Why does this code stop

[Ringo42]

Can someone please look at this and tell me why it stops after line 71.
On the output I get the initial stuff then I get to "RSSI 3" and then nothing.
If I comment out lines 75 to 85 then it runs. What is killing it there?

Thanks
Ringo

first.....

[Ringo42]

Thanks for the help,
I narrowed it down to the line
//output_high(MUX_Sel);//radio

with it commented out it runs.

The .lst file is below.

I'll disable watchdog for now

Compiler Version 4.007

I'll change the ADc to ADC_CLOCK_DIV_32. It is listed as have a max freq of 20mhz. In the pic datasheet there is a div/64 but I dont see that option in the CCS manual, should I use something else?

You are correct the radio is 3.3V and the pic is 5V, but the only problem I see with this is not getting full range correct? The Rssi is a PWM value that I filter into an analog signal.

I can send a schematic, but don't see how to attach it here. Am I missing an attachment button somewhere?

Your include file stddef.h is not needed. It's not used by your program.
But it fills up the .LST file and exceeds the amount of code that the forum
program can handle (it gets cut off). Delete #include stddef.h.

How to post an image on the CCS forum:
Use http://www.postimage.com or http://www.imageshack.com
or some other free image hosting service.
Upload your schematic to that website. Preferably a .JPG file or some
other commonly used image format.
Then post a link to your image here in the forum.

[Ringo42]

Here is the lst file without stdlib, hopefully that helps

Here is a PDF of the schematic
http://postimg.org/image/pwk8htn57/

I asked support about an upgrade, guess I'll see what they say.
Thanks

[PCM programmer]

[Ringo42]

I get nothing when I run that code. I added a couple lines and now I get the first print statement. The pin does go high though. I put an LED on it.
The jumper block just sends the signal to the mux.

[Ringo42]

Something is gotta be wrong here. I changed the pin to one that goes nowhere and it doesn't run. Then I did not use a pin at all.

[PCM programmer]

Here's an old post from 2008 where you say delay_ms() doesn't work
correctly with vs. 4.007.
http://www.ccsinfo.com/forum/viewtopic.php?t=36003

[temtronic]

couple of 'issues'..

The schematic show a PIC16F877 but code shows 18F452......

which is the real PIC ?


The RSSI PWM output will only ever get to about 3 volts,about 2/3 of the 877 ADC range....

Jay

[Ringo42]

Google found the old post. Damn my bad memory. I don't remember that issue at all, but it has been a long time since I worked on this.

Yes it really is a 452. I'm not concerned about the 2/3 range stuff.
I'll fix the delay_ms and see if that does it.
Thanks PCMP

well it is not the delay.
This does not run either

[Ringo42]

oops here is the lst

[PCM programmer]

I installed PCH vs. 4.007 and compiled your program above, and I ran it
on a PicDem2-Plus (old version) and it basically worked:

[Ringo42]

I'm using an ICD-U64. I just did a verify and it passed.
