//**********************Weighing related*************************
//Read the range information --- before accessing the weighing related interface function, the obtained range information truthfully displayed on the application interface.
int read_baseinfo(char *buf)
The length of buf should be greater than or equal to 65 bytes
Return value:
HS_OK
HS_ERROR
If you return to HS_OK, then the measurement range information is obtained successfully. The data structure is as follows
long max_range[3]; //maximum capacity 
long min_range; //minimum capacity 
long max_tare; //Maximum tare weight
long max_pre_tare; //Maximum preset tare weight
long resolution[3]; //Graduation
char Weight_unit[4];//weight
char money_unit[4]; //Monetary unit
char system_version[20];//Data transmission version
 
//Clearing
int send_zero(void)
Return value:
HS_OK, success
1    It is not allowed to clear when it is unstable and under load
2    Load out of peeling range
3    Overload beyond peeling range
-1   abnormal
-2   Abnormal data communication
-3   In data transmission: syntax, logic / unable to execute, internal function error
-8   And idnet_Service connection failed
-9   And idnet_Service data communication error
 
//Set tare to be compatible with old interfaces
int send_tare(char *buf)
Parameters:
The length of buf must be greater than or equal to 10 bytes.
The value in buf is an empty string or "0" or "0.000"
         1If there is tare weight, if gross weight = 0, clear tare weight; otherwise, if net weight is greater than 0, press key to remove tare weight
         2If there is no tare, press the key to remove the tare
If buf is tare string, it means preset tare. For example, if the tare value string needs to be set, such as 20g, the parameter is string "0.020".
Return value:
HS_OK, the current tare weight is stored in buf
1    Operation prohibited in case of non-compliance
2    Underload
3    Overload beyond peeling range
4    Parameter exception
5    Data processing exception
When returning to HS_When OK, it indicates that the current tare operation is successful, and the actual tare value after operation will be stored in buf. If the tare value after tare operation is 20g, the content in buf is "00.0200".
 
//Set the preset tare weight and remove the tare according to the tare weight parameters
//The parameter buf is used as both the incoming parameter and the return tare, and the length should be greater than or equal to 10 bytes
int send_pre_tare(char *buf)
Parameters:
If the tare value string needs to be set, such as 20g, the parameter is string "0.020".
If the parameter is an empty string or equal to "0.000", the function is equivalent to clearing tare.
Return value:
HS_OK, the current tare weight is stored in buf
1    Operation prohibited in case of non-compliance
2    Underload
3    Overload beyond peeling range
4    Parameter exception
5    Data processing exception
 
//Press the key to remove the skin, and automatically remove the skin according to the current weight on the scale
//The parameter buf is used to return tare weight, and the length should be greater than or equal to 10 bytes
int set_tare_bykey(char *buf)
Return value:
HS_OK, the current tare weight is stored in buf
1    Operation prohibited in case of non-compliance
2    Underload
3    Overload beyond peeling range
5    Data processing exception
 
//Remove tare
//The parameter buf is used to return tare weight, and the length should be greater than or equal to 10 bytes
int clear_tare(char *buf)
Return value:
HS_OK, the current tare weight is stored in buf
1    Operation prohibited in case of non-compliance
2    Underload
3    Overload beyond peeling range
5    Data processing exception
 
 
//Read the weight
int read_standard(char *buf)
The length of buf should be greater than or equal to 18 bytes
Return value:
HS_OK, success
-1       Underload
-2       overload
HS_Error exception
If you return to HS_OK, the weight information is obtained successfully, and the data structure is as follows
char status; 
//Bit0 (the first bit) of status indicates whether it is stable or not. If it is 1, it means stable
//Bit1 (the second bit) of status indicates whether it is in the zero position. If it is 1, it means the zero position
//Bit2 (the third digit) of status indicates whether there is tare weight. If it is 1, there is tare weight
char net_weight[7];
char FixSeparator;//Fixed as "P"
char tare_weight[7];
    
    When under load, net_The data in weight is "━", and the return value is - 1
    When in overload state, net_The data in weight is "━┓", and the return value is - 2
