Hi, I'm new in flowcode.
I am having a trouble with the ROM memory, it's 100% unused, why all the memory used is RAM??
All the code goes to the RAM in the free edition?

Code: Select all

RAM available:68 bytes, used:94 bytes (138.2%), free:-26 bytes (-38.2%), 
Heap size:0 bytes, Heap max single alloc:0 bytes
ROM available:1024 words, used:0 words (0.0%), free:1024 words (100.0%)

Thanks! and sorry for my english

I've noticed that when the ROM is full the ram is used

.
I'm using less instructions but it's not enough for my purpose

Hi lightbug,
If your using too many variables or using variable assigned to floats which takes up lots of RAM in calculations

Code: Select all

RAM available:68 bytes, used:94

Therefore there is not enough RAM (you're using 94 bytes when your target device has a total of 64 bytes available) then ROM will be reported as 100% not used since compiling was unsuccessful.
You will need to selected a target device with more RAM as possible and/or re-look at your variables and calculations you're using.
It maybe a good idea to post your flowchart so we can help you further.

Hi martin, thanks! I was hoping that change the target device was the last thing to do. I'm using 16f84a (yeah I know

) and trying to make a frequency meter, the problem comes with the mantissa of the frequency (comparison of float numbers), so the memory is not enough. Maybe the way i am doing this is wrong

I uploaded the fcf file
