在设计嵌入式系统重新时

需要考虑软复位的情况,

软复位时 很多变量都需要重置为初始值,

如果一个个去赋值 很麻烦,

下面是一个简单的办法

主要是对结构体 复位的方法:

#include <stdint.h>typedef struct {uint8_t reg1;uint8_t reg2;uint8_t reg3;
} StruSimuStat1;typedef struct {uint8_t state1;uint8_t state2;uint8_t state3;
} StruSimuStat2;typedef struct {uint16_t wqt1;uint16_t wqt2;
} StruSimuWQT;// 默认值
StruSimuStat1 zonereg = {0xEF, 0x30, 0};
StruSimuStat2 powertstate = {0, 0, 0};
StruSimuWQT WQTReg = {0, 0};
uint16_t uTxFrame[14] = {0x01, 0x02, 0x03, 0x04, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF};// 复位函数
void resetDefaults() {zonereg = (StruSimuStat1){0xEF, 0x30, 0};powertstate = (StruSimuStat2){0, 0, 0};WQTReg = (StruSimuWQT){0, 0};uint16_t defaultTxFrame[14] = {0x01, 0x02, 0x03, 0x04, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF};for (int i = 0; i < 14; i++) {uTxFrame[i] = defaultTxFrame[i];}
}
