TSS 3.1 C++ wrapper question :)

kazola — Wed, 17 Dec 2014 14:50:05 GMT

Hi,

I just built the FRDMKL05Z_DEMO_CPP example :smileyhappy:

However, size is soooo big, close to maximum 32K.

text	data	bss	dec	hex filename
26860	48	3644 30552	7758 FRDMKL05Z_DEMO_CPP.elf
26860	48	3644 30552	7758 (TOTALS)

Code optimization is maximum (-Os). Is there a way to shrink the size of this library down? For example, I'm just using ASlider, I do not need Rotary functions, perhaps I can omit them? :smileyhappy:
Also, does this library contains any code for proximity functions? I think not! Let me know again :smileyhappy:
Finally, which is the smallest code needed for proximity + touch functions? With Processor Expert and no C++ wrapper I have been able to achieve, around 20 K, as far as I remember.

Please let me know your thoughts about the 3 questions! Have a nice day.

Hi Kazola

unfortunately the Simple Low Level function is not available for the kinetis family, this only works for the S08 and the coldfire V1,

but I create a simple code with PE that set the Aslider with only one control and I get

text	data	bss	dec	hex filename
23460	36	820 24316	5efc FRDMKL05Z_TSS_PE.elf

this is not 20K but is less than 30K

Have a great day,
Vicente

Hi,

you should definitely look at your makefile / project settings. Probably using CW, so there is still space for improvement. When I build this demo in IAR, this are sizes reported in the map file

19 892 bytes of readonly code memory

1 446 bytes of readonly data memory

1 649 bytes of readwrite data memory

You can always squeeze some bytes also checking the TSS config and turn off funtionality which you dont need.
