Functions

void lv_nuttx_dsc_init(lv_nuttx_dsc_t *dsc)

Initialize the lv_nuttx_dsc_t structure with default values for the NuttX port of LVGL.

Parameters:

dsc – Pointer to the lv_nuttx_dsc_t structure to be initialized.

void lv_nuttx_init(const lv_nuttx_dsc_t *dsc, lv_nuttx_result_t *result)

Initialize the LVGL display driver for NuttX using the provided configuration information.

Parameters:

  • dsc – Pointer to the lv_nuttx_dsc_t structure containing the configuration information for the display driver.

  • result – Pointer to the lv_nuttx_result_t structure containing display and input device handler.

void lv_nuttx_deinit(lv_nuttx_result_t *result)

Deinitialize the LVGL display driver for NuttX.

Parameters:

result – Pointer to the lv_nuttx_result_t structure containing display and input device handler.

void lv_nuttx_init_custom(const lv_nuttx_dsc_t *dsc, lv_nuttx_result_t *result)

Initialize the LVGL display driver for NuttX using the provided custom configuration information.

Parameters:

  • dsc – Pointer to the lv_nuttx_dsc_t structure containing the custom configuration for the display driver.

  • result – Pointer to the lv_nuttx_result_t structure containing display and input device handler.

void lv_nuttx_deinit_custom(lv_nuttx_result_t *result)

Deinitialize the LVGL display driver for NuttX using the provided custom configuration information.

Parameters:

result – Pointer to the lv_nuttx_result_t structure containing display and input device handler.

void lv_nuttx_run(lv_nuttx_result_t *result)

Call lv_timer_handler() (LVGL's super loop) in an endless loop. If LV_USE_NUTTX_LIBUV is enabled an UV timer will be created, else lv_timer_handler() will be called in a loop with some sleep.

Parameters:

result – pointer to a variable initialized by lv_nuttx_init() or lv_nuttx_init_custom()

uint32_t lv_nuttx_get_idle(void)

Get the idle percentage of the system.

Returns:

The idle percentage of the system.
