Description
What MCU/Processor/Board and compiler are you using?
I am using esp32UE
What do you want to achieve?
Solve the screen freeze issue.
What have you tried so far?
I tryed changing tasks as lv_task_t, esp_timer_handle_t and finally I am using freertos task
Code to reproduce
Add the relevant code snippets here.
#define lv_task_handler_time 5000
#define lv_tick_task_time 1000
#define lv_task_create_time 1000
void task_update(lv_task_t task)
{
// Updated valueswhich will be shown on the screen
}
static void lv_task_handler_task(void){
while (1)
{
printf("esp_get_free_internal_heap_size() - %ld\n",esp_get_free_internal_heap_size());
printf("esp_get_free_heap_size() - %ld\n",esp_get_free_heap_size());
lv_task_handler();
vTaskDelay(pdMS_TO_TICKS(lv_task_handler_time));
}
}
static void init_disp(void){
tft_interface_displaySetup();
tft_interface_displayBackgroundColor(LV_COLOR_BLACK);
aqi_display_aqi_tftApplication();
vTaskDelay(pdMS_TO_TICKS(100));
/* Create and start a periodic timer interrupt to call lv_tick_inc */
const esp_timer_create_args_t periodic_timer_args = {
.callback = &lv_tick_task,
.name = "periodic_gui"};
esp_timer_handle_t periodic_timer;
ESP_ERROR_CHECK(esp_timer_create(&periodic_timer_args, &periodic_timer));
ESP_ERROR_CHECK(esp_timer_start_periodic(periodic_timer, LV_TICK_PERIOD_MS * lv_tick_task_time));
lv_task_t *task = lv_task_create(task_update, lv_task_create_time, LV_TASK_PRIO_MID, NULL);
aqi_display_tft_interface_displayturnON(true);
xTaskCreate(&lv_task_handler_task, "lv_task_handler_task", 2048, NULL, tskIDLE_PRIORITY, NULL);
}
