返回值:

Pointer -- Thread pointer.

void lvgl_host_thread_check(const char *file, const char *func)

Check if current thread is lvgl host thread (gui_thread). Make sure API be invoked in host thread only.

参数:

  • file -- The file name that calls this function. which used to log out

  • func -- The function name that calls this function. which used to log out

rt_err_t send_msg_to_gui_thread(void *data, uint32_t len, void *cb, uint32_t user_data, wakeup_ui_t wakeup)

Generate a message, Send it to gui thread. This function will apply a memory block(message) to copy the content of data using service_msg_fill. Therefor, after processing data, it is necessary to release this message using service_msg_rel.

参数:

  • data -- The Pointer of data content

  • len -- The length of data content

  • cb -- After gui_thread_queue received, it will call this cb to process this message.

  • uerdata -- User data.

  • wakeup_ui_t -- Indicated if need to wake up the UI when sending messages to UI.

返回值:

rt_err_t -- RT_EOK or RT_ERROR.

rt_err_t send_msg_to_bg_thread(void *data, uint32_t len, void *cb, uint32_t user_data)

Generate a message, Send it to background(bg) thread. This function will apply a memory block(message) to copy the content of data using service_msg_fill. Therefor, after processing data, it is necessary to release this message using service_msg_rel.

参数:

  • data -- The Pointer of data content

  • len -- The length of data content

  • cb -- After bg_thread_queue received, it will call this cb to process this message.

  • uerdata -- User data.

返回值:

rt_err_t -- RT_EOK or RT_ERROR.

rt_err_t send_msg_to_gui_thread_e(comm_msg_t *msg, wakeup_ui_t wakeup)
