$ cmake ..
then, you will get the serial port's project files. And also, you could use the following cmd to compile your program:
cmake --build .. --config Release
If you wanna receive data, you should definite anther class to inherit irecv_data class and implement the on_recv_data function. Thus, you could get the data from serial port in the on_recv_data function.
4,1 include file:
#include "serial_port/serial_port_interface.h"
4.2 use namespace lib_sp:
using namespace lib_sp;
4.2 initialize
serial_port_prop spp;
spp._name = std::string("COM" + to_string(sp_id));
int ret_val = sp->init(spp);
4.3 open
int ret_val = sp->open();
4.4 send data
const char arr_send[] = {"123ABC-=+"};
int ret_val = sp->send(arr_send, sizof(arr_send));
4.5 to check if opened
bool is_open = sp->is_opened();
4.6 close serial port
int ret_val = sp->close();
4.7 to get information of library
std::string str_ver = sp->get_version();
cout << "version = " << str_ver.c_str() << "\n\n"; // 1.0.0.18-09-2020
4.8 to receive data
Definite another class inherited irecv_data class to receive data, Like this:
class serial_port : public irecv_data
{
// ...
}
then ,set the second parameter of init to this :
// if you wanna recv data, set the second param this, otherwise, set it nullptr
_psp->init(spp, this);
4.9 to create an library object
You could call sp_create_win(in the serial_port_interface.h) function to create an object
iserial_port *_psp = sp_create_win();
4.10 to release an object
You must call sp_release to release the object created by sp_create_win function.
sp_release(_psp);
You could get further information to use it from xx/serial_port/example/shared/main.cc
Note These tools only works on Windows If you dont have any physical serial port, Configure Virtual Serial Port Driver could create more available virtual serial port pairs. Note, virtual serial port must be used in pairs. Like 10 and 20, 11 and 21
6.1 configure serial port
use Configure Virtual Serial Port Driver to add and delete serial port pairs
6.2 Access port
This tool could monitor and communicate with serial port.
