环境是esp-idf v4.4.3,用的是官方的timer_group例程
修改如下
修改如下
Code: Untitled.c Select all
timer_config_t config = {
.divider = TIMER_DIVIDER,
.counter_dir = TIMER_COUNT_DOWN,
.counter_en = TIMER_PAUSE,
.alarm_en = TIMER_ALARM_EN,
.auto_reload = auto_reload,
}; // default clock source is APB
timer_init(group, timer, &config);
...
timer_set_counter_value(group, timer, timer_interval_sec * TIMER_SCALE);
