@XuNeo I think this is a limitation of Kconfig (or the way our build system works), it is not dynamic. If we modify some Kconfig and don't run "make menuconfig"...

@XuNeo another point: is it possible to integrate your lua+lvgl binding (https://github.com/XuNeo/luavgl) into nuttx-apps?

Nice idea @tobiasjaster !!! Also adding support to SX1509 chip is a good idea!
