problem with hmi example

[zhuanghalin]

Hi ALL:
I had try two example in example/hmi,With the default configuration,compiling is OK,but while I change the lcd driver to SSD1306,compile faile,

This is the compile result of example/hmi//lvgl_example:

Code: Select all

# make
LD build/lvgl_example.elf
D:/esp/esp-iot-solution/examples/hmi/lvgl_example/build/main\libmain.a(app_main.o):(.literal.app_main+0x18): undefined reference to `lvgl_indev_init'

this is the compile result of example/hmi/ugfx_example:

Hi, if you want change screen ,please :

- Run make menuconfig and in "LVGL Settings" turn "LittlevGL Touch Screen Enable" on as the program uses a touch screen.
- Run make menuconfig and in "LVGL Settings >> Config Driver" set the screen driver to "Choose Screen Driver (ILI9341)"
- Run make menuconfig and in "LVGL Settings >> Config Driver >> ILI9341 Screen Pin Configuration" set all the GPIO numbers to the correct values.

if you don't have touch screen , you should comment `lvgl_indev_init` as it's used as initialize touch screen.

I'm encountering similar issues, namely:

Code: Select all

error: implicit declaration of function board_lcd_set_orientation

When trying to boilerplate out a uGFX + SSD1306 example
