Flowcode Support Board

Hello,

Can anyone here help me? I always get an error message when compiling, but I don't know exactly what this means and where the error lies...
Thank you very much

Chris

Looks like there is insufficient memory on the target device..


If you post your code someone will tell you what is too big... Region text overflowed by 176 bytes

Hi Martin, thank you. Here is the code

maybe the memory of the eprom is too small?

maybe the memory of the eprom is too small?

Yes...

Compiling for a different ATMega MCU - gives Text 8914...

The ATMega8 has just 8K

There are 2 options...

1) Use an MCU with more memory.
2) Refactor your code. The simplest thing to do is pull 'duplicate' code into a separate macro (there are quite a few places where you 'toggle a pin' until A=100 for example) - which would probably do the trick..

Martin

Great, thank you! Too bad the compiler doesn't just say: too little memory

It did....

Just an awful lot of cruft to wade through as well

Such is the nature of the beast.
