Emwin Touch Calibration

Am using iMXRT 1064 device with touch screen LCD and Emwin graphical library v5.50

Am using analog touch screen driver and using function GUI_TOUCH_Calibrate to calibrate the touch.

for compilation using MCUXPresso 11.1 but am getting a compiler error for the function call GUI_TOUCH_Calibrate

"undefined reference to `GUI_TOUCH_Calibrate"

pastedImage_1.png

my gui.h contains the prototype definition for GUI_TOUCH_Calibrate.

pastedImage_3.png

if any other touch function is used such as GUI_TOUCH_EnableCalibration it compiles successfully so emwin header includes for my project seems to be correct.

Are analog touch screen driver functions supported in the emwin version 5.50

is there any configuration macro which needs to be enabled please let me know.

I compiled the same on evkmimxrt1064_emwin_gui_demo sample project from SDK and observing the same error.

Please let me know as this is critical to our project.

Thanks

Regards,

Anuj
