Thread: Waiting for a specific character through a port

Post your code.

So do you want something like

Code:

while(input != '#') ;

?

i have tried that but the thing just doesnt work.

the program starts up and closes itself after 3 or 4 seconds.

ok guys, the string starts with a # and finishes with a "newline character"

so i want to start reading when i encounter the # character and stop when i encounter the newline. So far, the program starts reading at the # and stops reading at the newline HOWEVER, for some reason it doesnt "wait" until the newline character is received before reading.

thus i have to introduce a "sleep". if i set the sleep to 1ms then it shouldnt affect the program as it should start reading from the #. however, the program reads a few lines and then stops....

this is my code so far

Code:

     

//     while(sio_getch(port) != '#'){}
//commented out because the program starts and stops immediately if this line is left in
			
Sleep(1250);

            memset(streaminput, 0, sizeof(streaminput));
            memset(aux, 0, sizeof(aux));

            while (sio_getch(port) != 35) { }

            while (aux[0] != 35)
                {
                aux[0] = sio_getch(port);

                strcat(streaminput, aux);

                if (aux[0] == 10 || aux[0] == 13)
                    break;
                }

Code:

            while (sio_getch(port) != 35) { }

            while (aux[0] != 35)
                {
                aux[0] = sio_getch(port);

                strcat(streaminput, aux);

                if (aux[0] == 10 || aux[0] == 13)
                    break;
                }

In order to end the first while loop, the char must be 35. And the next loop starts only if the char isn't 35. Therefore, your second while loop never executes. (Maybe change it to while(1)?)
