error: 'BCKL' undeclared (first use in this function)

[ChrisVonFrosta]

i started with a new project. copied the lv_config.h (to /.pio/libdeps/) and main.cpp from the example and the folder boards to / (root folder where scr, lib, include,... are)
building end with errors:

.pio/libdeps/sunton-s3/esp32_smartdisplay/src/esp32_smartdisplay.c: In function 'smartdisplay_init':

what did i forgot?

btw way: greate idea for the clean libary and sharing it. Thank you!

i tried it quick and dirty with including those in esp32_smartdisplay.h

#define BCKL 42
#define LCD_WIDTH 800
#define LCD_HEIGHT 480

but ends in next errors:

You also need to update the submodule boards!

[ChrisVonFrosta]

i have not git for this project.
but i get it with the env var board

(i customized one for my non yellow display board)

[platformio]
;  default_envs = esp32-8048S070C
default_envs = esp32-ZX7D000CE1S

[env]
platform = espressif32
; board = esp32-ZX7D000CE1S
;board = esp32-8048S070C
;board = sunton-s3
framework = arduino
lib_deps = rzeldent/esp32_smartdisplay@^2.0.3

;  [env:esp32-8048S070C]

Hi Chris,

Just adding a board will not work. I defined all the boards and harware settings etc...
Normally the boards directory is included using a submodule.
Take a look in the boards directory. Maybe you can adapt a definition for your board....

You also need to update the submodule boards!

I had the same issue but for a supported "esp32-2432S032" and I solved it with

git submodule update --remote boards/

which now includes this change from just yesterday:

So now I can start with the actual development

Thanks for providing this library
