Description
I use label object to refresh some datas in a task, because data’s length is flexible, so I use function lv_label_set_static_text , and I set the long mode LV_LABEL_LONG_SCROLL_CIRC , but it doesn’t work. But If I put the document’s example code it works well. It confused me.
What MCU/Processor/Board and compiler are you using?
What do you want to achieve?
What have you tried so far?
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:
/*\brief clear_all_table_cells
* 清除整个表格的所有单元格
*/
static void clear_all_table_cells(void)
{
/* 清空序号 */
for (int i = ALARMINFO_ROW1; i < ALARMINFO_ROWNUM; i++)
lv_table_set_cell_value(AlarmInfoObj.AlarmInfoTable, i, ALARMINFO_COL1, " ");
for (int i = ALARM_1; i < ALARM_NUM; i++)
{
memset(AlarmInfoRuntime.EventTimeStr[i], 0, sizeof(AlarmInfoRuntime.EventTimeStr[i]));
memset(AlarmInfoRuntime.EventPointStr[i], 0, sizeof(AlarmInfoRuntime.EventPointStr[i]));
memset(AlarmInfoRuntime.EventTypeStr[i], 0, sizeof(AlarmInfoRuntime.EventTypeStr[i]));
memset(AlarmInfoRuntime.EventDescStr[i], 0, sizeof(AlarmInfoRuntime.EventDescStr[i]));
strncpy(AlarmInfoRuntime.EventTimeStr[i], "", MAX_NAME_LEN);
strncpy(AlarmInfoRuntime.EventPointStr[i], "", MAX_NAME_LEN);
strncpy(AlarmInfoRuntime.EventTypeStr[i], "", MAX_NAME_LEN);
