| CCS compiler overwriting SFRs |
 Posted: Mon Jun 25, 2018 4:39 pm |

I'm pretty sure I saw something related to this on this forum and was just wondering if someone had an solution.
Right now I have a program that keeps assigning float variables to weird memory addresses. They are trying to store them in SFR locations 0xF81-0xF83.
Because of this the float values aren't being written to and always outputting 0.0000.
If I make a duplicate of the floating points giving me my problem, and just leave the original variables untouched. The duplicate floating points will get assigned a proper register value and everything will work fine.
I read somewhere on here that it might be my compiler version but I was seeing if there was another way to fix this problem.
compiler version 5.046

Your posted code doesn't compile because of various missing items.
How are we going to solve this if we don't have a compilable test program
to look at ? |

Along with what PCM P says...
just some observations...
1) why the cryptic 0x7A12 when a simple delay_us(31250); will work and show how long the delay is ?
2) enabling the WDT should only be done in the final version of code
3) since you have ICD=TRUE, that will alter the overall operation of the PIC and the code
4) running the PIC at 4 MHZ seems 'silly' to me, especially with the number of floating point calculations the program has.They along might actually trip the WDT
5) some lines are commented out,well a lot of them,along with a lot of 'includes'. ALL 'commented out' code should be deleted in a posted program. One of those 'less is better' ideas. It helps others concentrate on real code and not get distracted with stuff that isn't happening in the PIC.
6) anytime you have a #use RS232(...options..) you need to add 'ERRORs' to the option list when using the HW UARTs.
7) I don't see where any of the float variables are 'defined ' IE: you have int16 degrees_raw before main() but no float degrees3. I've seen it said here that the compiler requires variables defined( or whatever the term is, I'm NOT a student of C) before main().
8) I don't know(since I seldom use floating points) , but when you do a compare,say if(pump_voltage3 >14), is the '14' converted to the floating point 14.0000 ? To me 14 and 14.0000 can be 2 different numbers within the code and the PIC.
What I do know is that integers, even scaled integers are a LOT faster for the PIC to handle especially using a 'snail slow' 4MHz clock. |

One other comment. All of these:
| Code: |
//#include "Flow_Params.h"
//#include "f_proto.h"
#include "globals.h"
#include "defines.h"
#include "f26k22_regs.h"
#include "math.h"
#include "stdlib.h"
|
Should be _after_ you have setup the delays and RS232.
The standard layout for reliability, is:
Processor include
Fuses
Timing setup
any #pin_select if applicable
#use statements
_then_ the includes.
In this case WDT won't trigger, since with ICD selected this will be turned off. However if it was there could be a problem. The watchdog on this chip (worst case) triggers in just 3.5mSec. Your maths on the reading:
addition
division by 2
multiplication by 0.00488
subtraction
division by 100
at 4Mhz, takes 513uSec+1449uSec+358uSec+523uSec+1449uSec = 4292uSec. Not even allowing any time for actually reading and saving the variables. Result on a real chip the watchdog would trigger.....
Just work in integer. Use signed int16 values. Then:
| Code: |
adc_val=//However you read the adc. You don't actually show the code
adc_val*=49;
adc_val-=5000;
|
No averaging shown. Honestly better to do this by taking two readings rather than 'carrying forward' the last reading each time.
Now this gives 100 counts per degree. So 125 degrees is 12500 counts. If you think about it the sensor gives 1.75v at 125C. This is 358 counts on the ADC. 358*49 = 17542. Subtract 5000 gives 12542. Nominally 125.42C. One int16 multiplication and one subtraction. Takes 36uSec against the 4.3mSec!... 120* faster (and smaller code as well). Error in the maths only about 0.3%. Given the sensor itself only claims 3% accuracy, far better than is needed. |

| Thank Mr T for posting the 'how and why' reply ! Should be a sticky. Anyone wanting to do floating point should read your post !! I knew FP was slow ,but well over 100 TIMES slower !! It should be a real eye opener to every programmer !! |

Thanks for the awesome support guys!
To be honest this is my boss's code. He is a smart man but the way he writes code is very old school and can be a pain to follow.
I will talk to him today and make some changes to increase performance. I still don't understand why the compiler would give these floating points weird addresses that are already used by SFRs. I can switch to int16 instead of floats but I'm just curious how this happened?

Man I have a dream to one day be half as smart as some of you guys 
I didn't include all the files because they are quiet large. [/quote] |

We still don't have the code to compile it. There could easily be something in one of your unpublished files causing the problem. Any #locate statements?. Any #byte or #word statements?.
You need ideally to generate a smaller version of the code that you can distribute, which shows the problem, so we can test and see if the problem is the same on a different compiler.
Do a search yourself in the files. Any statement lines involving 'pump_voltage'?. |

Ok so there is a header file with #bit declarations that might be the problem:

Figured out the problem after posting the last reply.
Someone thought it was a good idea to use the same variable names
#bit Pump_Voltage = PORTA.1 //Pin 3 AN1
#bit _24VDC = PORTA.2 //Pin 4 AN2
#bit Pump_Current = PORTA.5 //Pin 7 AN4
float pump_voltage, _24VDC, pump_current;
Thanks for all your help!! I got educated on floating points that i will use for all future projects!! |

As I said:

Do a search yourself in the files. Any statement lines involving 'pump_voltage'?.
|
Hopefully that search was what led to finding it.... 
Aargh.
That is one reason why when working on reasonably serious code, I like to have the names 'self indicate'. So a 'bit' would normally always be xxx_b. A type would be xxx_t. etc.. It helps to avoid that sort of problem. |

Gee when I started this 'microcomputer' gig, variables were limited to TWO characters when using the 'high level' language of Microsoft BASIC ! When I used COBOL every variable was coded as xxx_yyy_zzz.
Nowadays you can probably use 254 characters to name a variable so it is sad (and frustrating) to see the 'fun' the OP has had with this code.

Also keep in mind there is a #case directive you can use to enforce casing. It would have saved you on 2 of those (they would have been separate variables), but the _24VDC would have still been a problem. |
