Creating New Fonts

[flano]

Andy,

Is there any doco on creating new fonts with the fontconv.exe and adding them to the library?

I have managed to create the .h, .cpp and .xml files and have added them into the directories as per the existing fonts. I have also added them to tft.h.

When I try to use the font I get the following compile error.

Code Select Expand


'Building target: PowerSupply.elf'
'Invoking: Cross ARM C++ Linker'
arm-none-eabi-g++ -mcpu=cortex-m3 -mthumb -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections  -g3 -T "C:\Users\mlanagan\Documents\Electronics\PowerSupply\Code\PowerSupply\system\f1hd\Linker.ld" -Xlinker --gc-sections -LC:\Cygwin\home\mlanagan\stm32plus\lib\build\debug-f1hd-8000000 -Wl,-Map,"PowerSupply.map" --specs=nosys.specs -o "PowerSupply.elf"  ./system/f1hd/Startup.o ./system/f1hd/System.o  ./system/LibraryHacks.o  ./PowerSupply.o   -lstm32plus-debug-f1hd-8000000

collect2.exe: error: ld returned 1 exit status

If I change the code back to one of the included fonts it works fine?

Any pointers would be appreciated.

Thanks Mike

Hi Mike,

You've done everything correctly as far as generating the source and header files go. It looks like the .cpp file is either not being compiled or it's not being linked. I don't see it in your linker command line which implies that you've compiled it into the library. Is that the case and can you check that?

Andy,

Thanks for your reply. My code was linking in an old version of the library, as I updated to 4.0.0 over the weekend.

Working fine now.

Thanks Mike
