Hi,

I was developing my first professional system, and it was compiling well, and I would use this hex file to simulate it on Proteus ISIS. This all happened until one time I could not compile the hex file. Could it be that the PIC I am using (as in 16F877A) cannot support the size of the program I am writing?

This is the log:

Thanks!

I have deleted a small chunk of the program, and I re-tried compiling...

There are some parts of the message which are now different to the one above it. What now?

Thanks

i found this thread:

http://matrixmultimedia.com/mmforums/vi ... piling+hex

which told me to follow up to:


http://www.matrixmultimedia.com/support ... .php?t=456

I will try it out and let you know.

Thanks

I tried inserting the register, and compiled the flkowcode for three times... I still can't compile.

This is the message (the part mentioning warnings etc only):

Too much code to fit in ROM, overfilled by:386 locations.

You are correct - the program is not compiling because the program is too big.

You are using the "student/home" version of Flowcode, which limits the amount of ROM (program memory) space to 4k - the device you are using actually has 8k available.

You have 2 solutions:

1) Cut down the program so that it fits into 4k
2) Upgrade your licence of Flowcode to the "professional" version, which will allow all 8k

The other post you mentioned does not apply to you because that user was already using the professional version.

Is there a way of finding out how big th eprogram is, so that I may calculate how much to cut down?
How much would an upgrade cost?

Thanks

The error message at the end of the compiler messages tells how much the program has exceeded the available space:

Too much code to fit in ROM, overfilled by:386 locations.

An upgrade is basically the cost between the two versions (student = Β£39 and pro = Β£99, so you would need to pay Β£60, plus VAT - which is Β£70.50).

I installed the registry patch from:

http://www.matrixmultimedia.com/support ... .php?t=456

Could this affect Flowcode bad? Maybe limiting anything else?

Thanks

No - that patch should not affect your version of Flowcode.

Ok thanks! Great software and great help!
