I just want to be a serial port to send and receive, add 1 to 100, then every accumulative results to a serial port, I will send and receive serial port on the other end two ports together spontaneously from closed, but the value is very large, sending and receiving in principle should be from 0 to 5050, debugging for a long time without a result, a great god, please help to look at, appreciate

CodePudding user response:

No debug, but I think it should be like this.

 
Void MainWindow: : on_sendMsgBtn_clicked () 
{
Int a, I; 
A=0; 
for(i=0; i<100; I++) 
{
A +=I; 
This - & gt; WriteMyCom (a); 
This - & gt; ReadMyCom (a); 
} 
}

{
Int a, I;
A=0;//initialize a
for(i=0; i<100; I++)
{
A +=I;
This - & gt; WriteMyCom (a);
//delay (10);//add a delay
This - & gt; ReadMyCom (a);
}
}

Thank you, I have solved, because I didn't give the inside of the initialization parameters,

Thank you, is that really because no for a given initial value, thank you,
