Difference between compilers in FC7 and FC8 ?

I’m trying to build a hex file from an earlier made .fcfx program. I have made a hex file from this program but in FC7. Now I have FC8 and I can’t get built a hex file from this .fcfx file. I have not changed anything in this file. It is still original.
I assume it has something to do with “space”.
Code: Select all
using updated 32-bit floating-point libraries; improved accuracy might increase code size
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\PIC\PIC_CAL_IO.c: 1189: (1358) no space for _main temps (3)
(908) exit status = 1
(908) exit status = 1
So, is there a different between the compiler used in FC7 and FC8 ?
Below is the full error log.

Hi.
There should be no difference between XC8 and XC8 in V7 and V8
My wild guess is you ran out of memory on the chip

Hi,
I’m sorry but this is the same chip. There is really no hardware change or program change. Just FC7 to FC8.
The program was made on Nov 15 2017 and successfully compiled with FC7.

Ok ,
not seeing the code we are only guessing

The compiler is the same for both version, however the components are not. FC8 components are slightly larger and as a result more memory is required.
Could could you look at the FC7 compiler output to check how much memory is being used and how much is available?

Hi,
Personally, If you want an 8 pin chip then go for something like 12F1840.
Much faster as 32MHz, much more memory and peripherals.
I agree with QMESAR in that its a memory space issue and run out because of what kersing has stated.

Thanks Kersing my feeling is still memory problem looking at the compiler message

I might be daft, but how does

suggest it is not a memory issue?

Thanks for the answers. I have time on Friday to check this is FC7 and see the memory details then. Chancing from chip is not a problem. ( I must make new PCB’s because the shape must be modified)
Can I run FC7 and FC8 together on one computer without conflicting each other ?

Running both FC7 and FC8 on the same PC should not be a problem.

Changing to PIC12F1840 (7KB) will not cause an issue as its pin for pin compatible with PIC12F675 (1.75KB).

Yes it can.
I have ran FC6, FC7, FC8 and FC9 on the same machine without any conflicts at all!

Thanks all for your help. I have decided to switch from PIC12F675 to a PIC12F1840 in this case for more memory.
If I compare the PIC12F1840 with the PIC16F18313 (Microchip recommends for the 12F675) Than the PIC12F1840 looks more better to use.
The PIC12F675 was running at 4MHz to safe battery power. I will do the same with the PIC12F1840.

I have replaced the 12F675 for the 12F1840. I was struggling with the speed of this chip. I have made the simply one second flash to test this. I change some settings and finally it works.
This chip will be used for a LED flashing program in the original chart.
I just wonder if these settings are correct. Attached is the one second chart.

Hi Frank,
Setting look correct to me.
The 12F1840 can go up to 32MHz.
To take the guess work out make it much easier for you, just search component s for
intosc
Then add the component to your dashboard.
Right click on the IntOsc component when on the dashboard and select properties.
Enter he required frequency and you will see the C code to copy and past.
In your case if enter 8MHz:
