3. 请问一下FR8016H硬件定时器该怎么调呢？

    我照抄SDK里提供的example，好像不管用

    	#include "driver_timer.h"
	static uint32_t tick0 = 0;
	static uint32_t tick1 = 0;
	static uint8_t tim0_run_num = 0;
	__attribute__((section("ram_code"))) void timer0_isr_ram(void)
	{
		timer_clear_interrupt(TIMER0);
		co_delay_10us(1);
		//timer_reload(TIMER0);
		if(tick0>10000) //1s
		{
			tick0 = 0;
			tim0_run_num++;
			if(tim0_run_num >= 4)
				timer_stop(TIMER0);
			co_printf("hwt0_us:%d,%d\r\n",timer_get_current_value(TIMER0),timer_get_load_value(TIMER0));
		}
		else
			tick0++;
	}
	__attribute__((section("ram_code"))) void timer1_isr_ram(void)
	{
		timer_clear_interrupt(TIMER1);
		co_delay_10us(1);
		//timer_reload(TIMER1);
		if(tick1>20000) //4s
		{
			timer_stop(TIMER1);
			co_printf("hwt1_us:%d,%d\r\n",timer_get_current_value(TIMER1),timer_get_load_value(TIMER1));
		}
		else
			tick1++;
	}

	void demo_timer(void)
	{
		co_printf("hardware timer demo\r\n");

		tick1 = 0;
		tick0 = 0;
		tim0_run_num = 0;
		timer_init(TIMER0,100,TIMER_PERIODIC);
		timer_run(TIMER0);

		timer_init(TIMER1,200,TIMER_PERIODIC);
		timer_run(TIMER1);

		NVIC_SetPriority(TIMER0_IRQn, 2);
		NVIC_EnableIRQ(TIMER0_IRQn);

		NVIC_SetPriority(TIMER1_IRQn, 2);
		NVIC_EnableIRQ(TIMER1_IRQn);
	}

    请问各位大佬，定时器是这么用的吗？
