reading csv file to form modbus request packet
-
hello all I'm reading a csv file which could contain numerous rows, then parsing it into my struct variables which make up my Modbus request packet. I have successfully parsed the csv file and assigned to appropriate struct variables. Now my question is how can I utilize the QT built in Modbus library to create my request packet to send to a port for my slave to receive????? here is my code from parsing the csv file
int main()
{struct mframe
{
unsigned short address;
unsigned short func_code;
unsigned short byte_count;
unsigned int startaddress;
unsigned short crc;};
string ConfigPath = "myname.csv";
//char getaddress(char addr);
//bool setaddress(char addr);mframe frame[1000];
int point_count = 0;
vector<vector<string> > matrix;
string line;
ifstream file(ConfigPath);
if (!file.is_open())
{
perror("error while opening file");
}getline(file, line, '\n'); //deletes first row of column headers
while (getline(file, line, '\n')) //find the endline charcater
{vector<string> vec; string linevec; istringstream ss(line);//allows for parsing each line while (getline(ss, linevec, ',')) { vec.push_back(linevec);//push the parsed data for that line into a vector } matrix.emplace_back(vec);//push each parsed line into another vector frame[point_count].address = stoi(vec[0]); frame[point_count].func_code = stoi(vec[1]); frame[point_count].byte_count = stoi(vec[2]); frame[point_count].startaddress = stoi(vec[3]); frame[point_count].crc = stoi(vec[4]); point_count++;}
cout << point_count << endl;
}```
//your code here
