Hi
I have done a custom message for a type uint64_t but how I do this for type double?
Here my code:
class EkfParameters : public ros::Msg
{
public:
typedef uint64_t _residual_type;
_residual_type residual;
EkfParameters():
residual(0)
{
}
virtual int serialize(unsigned char *outbuffer) const
{
int offset = 0;
*(outbuffer + offset + 0) = (this->residual >> (8 * 0)) & 0xFF;
*(outbuffer + offset + 1) = (this->residual >> (8 * 1)) & 0xFF;
*(outbuffer + offset + 2) = (this->residual >> (8 * 2)) & 0xFF;
*(outbuffer + offset + 3) = (this->residual >> (8 * 3)) & 0xFF;
*(outbuffer + offset + 4) = (this->residual >> (8 * 4)) & 0xFF;
*(outbuffer + offset + 5) = (this->residual >> (8 * 5)) & 0xFF;
*(outbuffer + offset + 6) = (this->residual >> (8 * 6)) & 0xFF;
*(outbuffer + offset + 7) = (this->residual >> (8 * 7)) & 0xFF;
offset += sizeof(this->residual);
return offset;
}
virtual int deserialize(unsigned char *inbuffer)
{
int offset = 0;
this->residual = ((uint64_t) (*(inbuffer + offset)));
this->residual |= ((uint64_t) (*(inbuffer + offset + 1))) << (8 * 1);
this->residual |= ((uint64_t) (*(inbuffer + offset + 2))) << (8 * 2);
this->residual |= ((uint64_t) (*(inbuffer + offset + 3))) << (8 * 3);
this->residual |= ((uint64_t) (*(inbuffer + offset + 4))) << (8 * 4);
this->residual |= ((uint64_t) (*(inbuffer + offset + 5))) << (8 * 5);
this->residual |= ((uint64_t) (*(inbuffer + offset + 6))) << (8 * 6);
this->residual |= ((uint64_t) (*(inbuffer + offset + 7))) << (8 * 7);
offset += sizeof(this->residual);
return offset;
}
const char * getType(){ return "arduino_vi_sync/EkfParameters"; };
const char * getMD5(){ return "429a0337b7125479e9bf5f4056e69192"; };
};
But how I do this for a type double. If I just change the type then I get a error message because << is not for type double. What can I do?
Thanks
