6 应用代码

为了方便更改看门狗计时器周期和复位脉冲长度，可修改 watchdog_hal.h 中的 #defines，如下代码块所示：

#ifndef WATCHDOG_FUNCTION_H_
#define WATCHDOG_FUNCTION_H_

#include"ti_msp_dl_config.h"

#define WATCHDOG_1s (32768)
#define WATCHDOG_500ms (WATCHDOG_1s/2)
#define WATCHDOG_250ms (WATCHDOG_1s/4)
#define WATCHDOG_125ms (WATCHDOG_1s/8)
#define WATCHDOG_100ms (WATCHDOG_1s/10)
#define WATCHDOG_50ms (WATCHDOG_1s/20)
#define WATCHDOG_25ms (WATCHDOG_1s/40)
#define WATCHDOG_12D5ms (WATCHDOG_1s/80)
#define WATCHDOG_10ms (WATCHDOG_1s/100)

#define delay_1s (24000000)
#define delay_20ms (delay_1s/50)
#define delay_10ms (delay_20ms/2)
#define delay_5ms (delay_20ms/4)
#define delay_2D5ms (delay_20ms/8)
#define delay_2ms (delay_20ms/10)


/* User defined */
#define WATCHDOG_PERIOD (WATCHDOG_1s)
#define WDO_RESET_TIME (delay_10ms)

void watchdog_start(void);
void watchdog_timeout(void);
void watchdog_reload(void);

#endif /* WATCHDOG_FUNCTION_H_ */
