unable to compile

[siliconchip]

hi all,
im a flowcode 7 user am i right that when you press build in the toolbar then compiler options then the linker/assembler tab there should be something in my parameters box this is empty and im having trouble compiling known good programs

Hi Bob,
Have you checked on Wiki page?
The images look wrong, but main writing looks correct.
Make sure you have the Default for PIC selected.

hi martin
in the supplementary code box im using #include <rand.h> i seem to recal ages ago i had to put something like srand in the linker/assembler as well ??

[siliconchip]

also the default is empty for the linker/assembler parameter on the wiki, when checking my flowcode 6 the linker/assembler has writing in it and seems to work fine

Hi Bob,

That correct.
Linker has got parameters for v6 and earlier, because the compiler was BoostC.
In v7 and later the compiler was changed to XC8, which does not use any linker parameters.
Try stating a new project with v7 , and compiling to hex without any code in supplementary code window.
Can you post uisng the forum Code icon compiler message of V7 flowchart that failed.
For example I have just done that:

If that works, retry the flowchart causing issues, without #include <rand.h> etc.

as for the supplementary code i was told to add this way back when i did this project as its a random number picker it worked fine a couple of years back now ive revisited i get the above message,if i remove the supplementary code will this stop the random element

Hi Bob,
Reason for error is because rand.h is required for boostC (Flowcode V6 and below).
Should not be required for Flowcode V7 and above.
Remove from supplementary code then Should compile OK, assuming no more BoostC only coding?

[siliconchip]

hi martin
i guess i will need to do as you say and remove the supplementary code but im sure ive compiled on flowcode 7 in the past and it worked and for some reason doesnt now when i get 5 mins i will check in hardware and let you know

cheers bob

[medelec35]

Hi Bob,
I have V6 and V7.
It won't compile to either because the Ccode

Code: Select all

srand(tmr01);

is wrong.
For V6 it should be

Code: Select all

srand(tmr0);

For V7 it should be

Code: Select all

srand(TMR0);

For future reverence.
To enable to work with V7 you need to use Ctrl + F (or Edit, Find/Replace)
In the Find enter tmr01, in the Replace with: enter TMR0
Then select replace all.
I will sort your flowchart out, and PM it back to you.

Hi Bob, I have sorted all the Ccode errors out.
You now have one serious issue.
There are several recursive function calls which are definitely not allowed by several compilers, one of which is XC8.
I would strongly recommend a state machine type flowchart.
The state will change for each required function call.
You can then use the Switch component (Icon just below decision branch) to call each function call depending on the state value.
I did that with a very complex touch screen heating controller with great success.
I will pm your flowchart back for you to look into state machine programming.

Hi Martin,
Thanks I messed with the tmr0 changing to tmr01 that was my fault originally it did work in flowcode 6 but I couldn't get it to work in 7 so started fiddling and forgot to revert back
