# 定时器设备
## 功能
* 时间测量
* 周期或单次执行回调函数
## 编译
1. 在rtconfig.h添加 `#define RT_USING_HWTIMER`
## 使用流程
1. 以读写方式打开设备
2. 设置超时回调函数（如果需要）
3. 根据需要设置定时模式（单次/周期）
4. 设置计数频率（可选）
5. 写入超时值，定时器随即启动
6. 停止定时器（可选）
7. 关闭设备（如果需要）
应用参考 [hwtimer_test] (/examples/test/hwtimer\_test.c)
## 驱动编写指南
### 操作接口
```
struct rt_hwtimer_ops
{
void (*init)(struct rt_hwtimer_device *timer, rt_uint32_t state);
rt_err_t (*start)(struct rt_hwtimer_device *timer, rt_uint32_t cnt, rt_hwtimer_mode_t mode);
void (*stop)(struct rt_hwtimer_device *timer);
rt_uint32_t (*count_get)(struct rt_hwtimer_device *timer);
rt_err_t (*control)(struct rt_hwtimer_device *timer, rt_uint32_t cmd, void *args);
};
```
* init - state <1 打开设备 0 关闭设备>
* start - cnt <超时值> - mode <单次/周期>
* stop - <停止计数>
* count_get - <读取计数器值>
* control - <设置计数频率 >
### 定时器特征信息
```
struct rt_hwtimer_info
{
rt_int32_t maxfreq;
rt_int32_t minfreq;
rt_uint32_t maxcnt;
rt_uint8_t cntmode;
};
```
* maxfreq <设备支持的最大计数频率>
* minfreq <设备支持的最小计数频率>
* maxcnt <计数器最大计数值>
* cntmode <递增计数/递减计数>
### 注册设备
```
static rt_hwtimer_t _timer0;
int stm32_hwtimer_init(void)
{
_timer0.info = &_info;
_timer0.ops = &_ops;
rt_device_hwtimer_register(&_timer0, "timer0", TIM2);
return 0;
}
```
### 定时器中断
```
void timer_irq_handler(void)
{
//其它操作
rt_device_hwtimer_isr(&_timer0);
}
```
## 注意事项
**可能出现定时误差**
误差原因：
假设计数器最大值0xFFFF，计数频率1Mhz，定时时间1秒又1微秒。
由于定时器一次最多只能计时到65535us，对于1000001us的定时要求。
可以50000us定时20次完成，此时将会出现计算误差1us。
