ESL Tag User Defined Display Driver#

esl_user_display_init#

sl_status_t esl_user_display_init (int param_count,...)

ESL Tag user defined display driver init function. Function naming is for reference, only - any arbitrary function naming can be used, freely. For more - and especially, different type of displays - there might be a good approach to implement more init functions, also. Then, these functions has to be assigned to the corresponding display during the esl_core_boot_event as follows:

sl_status_t void esl_core_boot_event(void)
{
 sl_status_t sc;
 esl_display_info_p info;

 sc = esl_display_create(<user_display_witdth>,
                         <user_display_height>,
                         <user_display_type>,
                         &info);
 app_assert_status(sc);

 sc = esl_display_add(info,
                      <your_init_function>,      // can be NULL if not needed
                      <your_write_function>);    // mandatory!

 app_assert_status(sc);
}

Note: please do not forget to add #include "esl_display.h", previously.

esl_user_display_write#

sl_status_t esl_user_display_write (int param_count,...)

ESL Tag display user defined driver write function. See the comments at esl_user_display_init function on naming and usage.
