Detailed Description

LittlevGL package for RIOT.

See also: https://github.com/littlevgl/lvgl

Configuration options

The package can be configured with using several variables. These variables can either be passed directly to build command line or set in the application Makefile.

Graphical settings

LVGL_COLOR_DEPTH: configure the color depth in bit of the screen (default: 16)
LVGL_COLOR_16_SWAP: enable byte swap when communicating with the screen driver (default: 1, enabled)

Memory settings

LVGL_MEM_SIZE: configure the maximum memory size used by lvgl. This depends on the number of lvgl widgets and objects used by the interface (default: 5U*1024U, 5KiB). Must be greater than 2KiB.

Engine settings

LVGL_INACTIVITY_PERIOD_MS: maximum inactivity period before going to sleep in ms. (default: 1s)
LVGL_TASK_HANDLER_DELAY_US: delay between lvgl task handle call in ms. (default: 5ms)
LVGL_TASK_THREAD_PRIO: lvgl task handler thread priority. (default: THREAD_PRIORITY_MAIN - 1)

Example of command line for changing the max activity period to 5s:

LVGL_ACTIVITY_PERIOD=5000 make -C tests/pkg_lvgl
