lvgl配置时钟有两种方式：

  • lv_tick_inc(uint time);

    比较简单一般用在mcu

  • lv_conf.h文件中定义 LV_TICK_CUSTOM为1

    一般用在linux和RTOS。需要给LV_TICK_CUSTOM_SYS_TIME_EXPR提供一个函数

    #define LV_TICK_CUSTOM 1
#if LV_TICK_CUSTOM
    #define LV_TICK_CUSTOM_INCLUDE <stdint.h>
    extern uint32_t custom_tick_get(void);
    #define LV_TICK_CUSTOM_SYS_TIME_EXPR (custom_tick_get())
#endif

    linux

    uint32_t custom_tick_get(void)
{
    struct timeval tv;
    gettimeofday(&tv, NULL);
    static uint64_t start = 0;
    if (!start) start = tv.tv_sec*1000ULL + tv.tv_usec/1000;
    return (uint32_t)(tv.tv_sec*1000ULL + tv.tv_usec/1000 - start);
}
