• Create an example project on GUI-Guider
• Copy the following directories to your project directory:
  • custom/
  • generated/
  • import/

If you want to add these directories in a GUI-Guider specific directory you need to change some makefiles.

Change from $(PRJ_DIR)/ to $(PRJ_DIR)/gui_guider/ in the following makefiles:

- generated.mk
- images.mk
- custom.mk
- guider_fonts.mk
- guider_customer_fonts.mk

• Declare a GUI-Guider struct on your code:

lv_ui guider_ui;

• Call the following functions on your startup code (after lv_init()):

setup_ui(&guider_ui);
events_init(&guider_ui);
custom_init(&guider_ui);
