uint8_t EMS_EngineCoolantTemperature; // 发动机冷却液温度 uint8_t EMS_EngineCoolantTemperaturelnvalid; // 发动机冷却液温度无效 uint8_t EMS_EnginePatsBatteryStat_AliveCounter; // 发动机防盗电池状态存活计数器 uint8_t EMS_EnginePatsBatteryStat_Checksum; // 发动机防盗电池状态校验和 uint8_t EMS_EngineReleaseSig; // 发动机释放信号 uint8_t EMS_EngineRPM_AliveCounter; // 发动机转速存活计数器 uint8_t EMS_EngineRPM_Checksum; // 发动机转速校验和 uint16_t EMS_EngineSpeedrPM; // 发动机转速 uint8_t EMS_EngineTorqueStatus_AliveCounter; // 发动机扭矩状态存活计数器 uint8_t EMS_EngineTorqueStatus_Checksum; // 发动机扭矩状态校验和 uint8_t EMS_EngStatus; // 发动机状态 uint8_t EMS_OilPressureWarning; // 机油压力警告 uint8_t EMS_PEPSAuth[8]; // PEPS身份验证 帮我写以上信号的return函数

好的，以下是以上信号的返回函数的示例代码：

uint8_t get_EMS_EngineCoolantTemperature() {
  return EMS_EngineCoolantTemperature;
}

uint8_t get_EMS_EngineCoolantTemperaturelnvalid() {
  return EMS_EngineCoolantTemperaturelnvalid;
}

uint8_t get_EMS_EnginePatsBatteryStat_AliveCounter() {
  return EMS_EnginePatsBatteryStat_AliveCounter;
}

uint8_t get_EMS_EnginePatsBatteryStat_Checksum() {
  return EMS_EnginePatsBatteryStat_Checksum;
}

uint8_t get_EMS_EngineReleaseSig() {
  return EMS_EngineReleaseSig;
}

uint8_t get_EMS_EngineRPM_AliveCounter() {
  return EMS_EngineRPM_AliveCounter;
}

uint8_t get_EMS_EngineRPM_Checksum() {
  return EMS_EngineRPM_Checksum;
}

uint16_t get_EMS_EngineSpeedrPM() {
  return EMS_EngineSpeedrPM;
}

uint8_t get_EMS_EngineTorqueStatus_AliveCounter() {
  return EMS_EngineTorqueStatus_AliveCounter;
}

uint8_t get_EMS_EngineTorqueStatus_Checksum() {
  return EMS_EngineTorqueStatus_Checksum;
}

uint8_t get_EMS_EngStatus() {
  return EMS_EngStatus;
}

uint8_t get_EMS_OilPressureWarning() {
  return EMS_OilPressureWarning;
}

// 返回一个指向PEPS身份验证数组的指针
uint8_t* get_EMS_PEPSAuth() {
  return EMS_PEPSAuth;
}

请注意，这只是示例代码，假设你已经在其他地方定义了以上变量。你可以根据你的实际需求进行修改和适应。
