Complete rework of LVGL's draw engine to use "masks" for more advanced and higher quality graphical effects. What is Micropython M5STACK LVGL is a set of UI component library developed based on LVGL.

h with USE_EQ3_ESP32 is 1310k Does this mean it adds 9K to the code size? It would be possible to add some 'enable' variable to ensure it is not active unless turned on in autoexec. It was built using the NXP SDK v2.6.1.Lvgl font size Depending on the other parts of the UI you can make test2 1-1 px greater in every direction: lv_obj_set_size (test2, 202, 202) Answered Aug 24 '21 at 12:34. The project containing all described steps can be downloaded ad imported directly to the MCUXpresso: FreeRTOS_HMI_demo.zip.

The SCL and SDA pins and the I2C controller are already configured in the imported MEX file, so we only need to add the code responsible for reading the touchscreen state and pass the results to the emWin library for further processing. The touch screen in the display module contains the FT5426 controller that is accessible using the I2C interface.

The full source code of both files is listed below. There is also a set of functions that provides the interface to the operating system, like delay and locking the resource. The source file defines the library buffer, functions responsible for LCD controller interrupts handling and image frames management. The header file contains the definitions related to the image orientation and the library buffers configuration. The emWin library is configured in two files: emwin/emwin_support.h and emwin/emwin_support.c.
