`uint8_t`和`uint32_t`是C/C++语言中的数据类型,它们分别代表8位和32位无符号整数。其中,`uint8_t`是一个无符号整数类型,它的取值范围是0到255,占用1个字节的内存空间;而`uint32_t`也是一个无符号整数类型,它的取值范围是0到4294967295,占用4个字节的内存空间。这两种数据类型通常用于需要精确控制数据大小和位数的场合,比如嵌入式系统、网络协议等。

uint8_t mHighestLevel; uint32_t mUniversalAlarmMark; uint8_t mChargeStorageFaultNum; uint32_t *mChargeStorageFaultCodeList; uint8_t mDrivMotoFaultNum; uint32_t *mDrivMotoFaultCodeList; uint8_t mEngineFaultNum; uint32_t *mEngineFaultCodeList; uint8_t mSelfDefFaultNum; uint32_t *mSelfDefFaultCodeList;写一下上面所有变量的set、get函数
以下是上述所有变量的set和get函数的示例代码:
```cpp
// Set and Get functions for mHighestLevel
void setHighestLevel(uint8_t value) {
mHighestLevel = value;
}
uint8_t getHighestLevel() {
return mHighestLevel;
}
// Set and Get functions for mUniversalAlarmMark
void setUniversalAlarmMark(uint32_t value) {
mUniversalAlarmMark = value;
}
uint32_t getUniversalAlarmMark() {
return mUniversalAlarmMark;
}
// Set and Get functions for mChargeStorageFaultNum
void setChargeStorageFaultNum(uint8_t value) {
mChargeStorageFaultNum = value;
}
uint8_t getChargeStorageFaultNum() {
return mChargeStorageFaultNum;
}
// Set and Get functions for mChargeStorageFaultCodeList
void setChargeStorageFaultCodeList(uint32_t* list) {
mChargeStorageFaultCodeList = list;
}
uint32_t* getChargeStorageFaultCodeList() {
return mChargeStorageFaultCodeList;
}
// Set and Get functions for mDrivMotoFaultNum
void setDrivMotoFaultNum(uint8_t value) {
mDrivMotoFaultNum = value;
}
uint8_t getDrivMotoFaultNum() {
return mDrivMotoFaultNum;
}
// Set and Get functions for mDrivMotoFaultCodeList
void setDrivMotoFaultCodeList(uint32_t* list) {
mDrivMotoFaultCodeList = list;
}
uint32_t* getDrivMotoFaultCodeList() {
return mDrivMotoFaultCodeList;
}
// Set and Get functions for mEngineFaultNum
void setEngineFaultNum(uint8_t value) {
mEngineFaultNum = value;
}
uint8_t getEngineFaultNum() {
return mEngineFaultNum;
}
// Set and Get functions for mEngineFaultCodeList
void setEngineFaultCodeList(uint32_t* list) {
mEngineFaultCodeList = list;
}
uint32_t* getEngineFaultCodeList() {
return mEngineFaultCodeList;
}
// Set and Get functions for mSelfDefFaultNum
void setSelfDefFaultNum(uint8_t value) {
mSelfDefFaultNum = value;
}
uint8_t getSelfDefFaultNum() {
return mSelfDefFaultNum;
}
// Set and Get functions for mSelfDefFaultCodeList
void setSelfDefFaultCodeList(uint32_t* list) {
mSelfDefFaultCodeList = list;
}
uint32_t* getSelfDefFaultCodeList() {
return mSelfDefFaultCodeList;
}
```
这些函数可根据需要在您的代码中使用,用于设置和获取相应的变量值。请注意,对于指针类型的变量,需要使用适当的内存管理方法来分配和释放内存。这些示例代码仅提供了函数的框架,您需要根据您的具体需求进行适当的实现。
struct CAN_Brake_Report{ uint32_t ID : 8; uint32_t PI : 16; uint32_t Timeout : 1; uint32_t Fault : 1; uint32_t Veh_block : 1; uint32_t NONE1 : 13; uint32_t PO : 16; uint32_t WorkMode : 3; uint32_t TYPEFB : 3; uint32_t OVERRIDE : 1; uint32_t Available : 1; uint32_t BrkRptChkSm : 8; };打印上面的结构体
这个结构体定义了一个表示刹车报告的数据类型,它包含了ID,PI,Timeout,Fault,Veh_block,PO,WorkMode,TYPEFB,OVERRIDE,Available以及BrkRptChkSm等字段。
