PSOC 6 GraphicLCDIntf 1.80 conflict with GPIO API

[VlYe_281166]

When using GraphicLCDIntf  (e.g. in Ce222221_Voice_Recorder example) changing GraphicLCDIntf from v.1.0 to v.1.80 causes errors:

undefined reference to `Cy_GPIO_Clr',

undefined reference to `Cy_GPIO_Set'

so, using Pins became inavailable.

At the first glance I could not find what is the reason.

Generated API files are the same.

Yes, I was able to reproduce your issue. For some reason, the GPIO functions weren't getting referenced. Please do the following and then it will work.

The error shows in tft_display.c. Open the file and include the following header file:

#include "gpio/cy_gpio.h"

I have included the updated project and the tft_display.c file for reference which builds successfully.
