My apologies for not speaking German. A note on the AVR_Transistortester
page suggests that members here are comfortable with English.
I hope to develop some additional features for the excellent
AVR_Transistortester but right now I am failing before I've started.
My tester is 328p-based with ST7735 display running software Version
1.12K (non-readable, as supplied), and I'd like to start as close to
that as I can.
I downloaded Karl-Heinz Kübbeler's "software-112k" branch and installed
the recommended WinAVR development system.
A test build using the ST7735 Makefile (no changes) exceeds available
memory by 11.7%:

I was surprised, but the "ST7735" options don't match my device
perfectly so I tried again using a slightly customised Makefile with a
similar result: 36506 bytes (111.4% Full).
I tried again using the supplied "mega328_st7565" Makefile (no changes).
This builds to 35458 bytes (108.2% Full).
So I'm a little stuck at this point. I get no error message but an
apparently successful build which is too large to fit in the target
memory. I notice the output "(.text + .data + .bootloader)" suggests a
bootloader is included. I don't need one but can't find it in the
Makefile so I guess it may simply be a misleading generic comment.
It has occured to me that incorrect optimisation options (or no
optimisation) might cause this but I'm expecting the Makefile to take
care of all that. If it's an incorrect build switch it could take me
days to find (I'm not familiar with any of this toolchain).
I expect this is actually trivial but I have searched all over and
probably missed it. Can anyone offer an explanation/help?
Many thanks.
