selection guide for details on the different library variants. Update the linker options to
specify the library to be linked
4) Specify the tunable configuration parameters for the project as illustrated in 5.6.11.3.2
5) For QMatrix on XMEGA devices, please check if the pre-processor symbol _ATXMEGA_
is added in the project space or not.
5.6.11.4 Adjusting the Stack size when using IAR IDE
The example projects for IAR IDE, the CSTACK and RSTACK values are configured to account
for the requirements of the QTouch libraries and the included main.c file which illustrates the
usage of the touch API.
?
Adjust the CSTACK and RSTACK values appropriately based on additional software
integrated or added to the examples.

5.6.11.5 Optimization levels
The default configuration settings in sample projects which ship with the library are set to the
highest level of optimization for IAR and GCC variants of the libraries. The user might be required
to change this setting for debugging purposes

?
?
In case of IAR, The optimizations tab in project configuration options specifies High.
In case of GCC, the libraries are compiled with the –Os which signifies that the
Optimization for generating the library is maximum.
